1. GENERAL DESCRIPTION OF THE THERMOSTAT
COMPUTHERM E800RF Wi-Fi thermostat is a switching device that can be operated by a smartphone or tablet via Internet, and we especially recommend it for controlling heating or cooling systems. It can be easily connected to any gas boiler having a two-wire thermostat connection point and to any air conditioning apparatus or electrical apparatus, regardless of whether they have a 24 V or 230 V control circuit.
The basic package of the device includes two wireless programmable Wi-Fi thermostats and a receiver. If required, it can be expanded with 6 more COMPUTHERM E800RF (TX) Wi-Fi thermostats. The receiver receives the switching signals of the thermostats, controls the boiler or cooling device (load capacity: max. 30 V DC / 250 V AC, 3 A [1 A inductive load]) and gives commands to open/close the heating zone valves (max. 8 zones, load capacity per zone 230 V AC, max: 3 A /1 A inductive/) belonging to the thermostats, as well as to start the pump connected to the common pump output.(load capacity per zone 230 V AC, max: 3 A /3 A inductive/). The zone outputs and the maximum load capacity of the combined pump output is 15 A (4 A inductive load).

An example of dividing the heating system into zones is shown in the figure below:
By dividing a heating / cooling system into zones, the various zones can operate either simultaneously or independently of each other. This way only those rooms are heated at a given time, whose heating is required. (e.g. the living room and bathroom during the day and the bedroom at night). More than 8 zones can be controlled by using additional COMPUTHERM E800RF (TX) thermostats (1 receiver per 8 zones is required). In this case, the potential-free boiler output (NO-COM) must be connected in parallel to the boiler and the zone outputs work independently. There is a wireless (radio frequency) connection between the thermostats and the receiver units, so there is
– 6 –

no need to build a wire between them. The thermostat and their receiver have their own security code, which guarantees the safe operation of the device. See Chapter 7 for installation, connection and synchronization of the receiver with the thermostats. The thermostat does not transmit continuously, but repeats its current switching command every 6 minutes, and heating/cooling control is provided even after a power failure, if this option is selected in the settings (see Chapter 11). The range of the transmitter installed in the thermostats in open field is approx. 250 m. This distance may be significantly reduced inside a building, especially if a metal structure, reinforced concrete, or adobe wall gets in the way of radio waves. The portability of the thermostat offers the following advantages:
· no need to lay a cable, which is especially advantageous when old buildings are being modernized,
· the optimal location of the device can be selected during operation, · it is also advantageous when you intend to locate the thermostat in different rooms in the
course of the day (e.g. in the living room during the day but in the bedroom at night). All thermostats connected to the multi-zone receiver can be easily controlled via both Internet and touch button interface, and its operating conditions can be checked continuously. The device also offers the option of automatic control based on temperature and time. Several thermostats, even installed in different locations, can be registered and controlled in the same user account
A COMPUTHERM E800RF thermostats can be used to control: · gas boilers · an existing heating/cooling system remotely · electric water heaters · solar systems · certain groups of other electric devices
– 7 –

With the help of the product the heating/cooling system of your flat, house or holiday home can be made controllable from any place and at any time. This product is especially useful when you do not use your flat or house according to a predefined schedule, you leave your home for an uncertain period of time during the heating season or you intend to use your holiday home during the heating season as well.
2. IMPORTANT WARNINGS AND SAFET Y RECOMMENDATIONS

6. LOCATION OF THE THERMOSTAT AND THE RECEIVER UNIT
It is expedient to install the thermostat in a room used regularly or for a prolonged stay, so that it is located in the direction of natural air movement in the room, but do not expose it to draughts of air or extreme heat effects (e.g. solar radiation, refrigerator or chimney). Its optimal position is at a height of 0.75-1.5 m from the floor level. The receiver of the COMPUTHERM E800RF thermostat should be installed near the boiler, in a place protected from moisture, dust, chemicals and heat. When selecting the location of the receiver, also take it into account that the propagation of radio waves is caused by large metal objects (eg boilers, buffer tanks, etc.) or metal building structures may be adversely affected. If possible, we recommend to install the receiver at a distance of at least 1-2 m from the boiler and other large metal structures, at a height of 1.5-2 m, to ensure interference-free radio frequency communication. We recommend to check the reliability of the radio frequency connection at the selected location before installing the receiver.
ATTENTION! Do not install the receiver under the boiler cover or in the immediate vicinity of hot pipes, as this may damage the components of the appliance and endanger the wireless (radio frequency) connection. To prevent electric shock, entrust a professional to connect the receiver unit to the boiler.
IMPORTANT WARNING! If the radiator valves in your flat are equipped with thermostat head then set the thermostat head to maximum level in the room where you intend to locate the room thermostat or replace the thermostat head of the radiator valve with manual regulating knob, otherwise the thermostat head may disturb the temperature control in the flat.

7. CONNECTION AND INSTALLATION OF THE THERMOSTATS AND THE RECEIVER UNIT
ATTENTION! Make sure that the COMPUTHERM E800RF thermostat and the apparatus to be controlled are de-energized while putting them into operation. The device should be installed and put into operation by a competent person! If you do not possess the necessary skills and qualifications, please get in touch with an authorized service! CAUTION! The modification of the device poses a risk of electric shock or breakdown! ATTENTION! We recommend that you install the heating system that you want to control with the COMPUTHERM E800RF multi-zone thermostat in such a way that the heating liquid can circulate in the closed position of all zone valves in case that one of the circulation pump is switched on. This can be achieved with a permanently open heating circuit or by installing a by-pass valve. 7.1. Putting the thermostat into operation Connect the front of the thermostat to its holder, then connect the USB-C power cable to the back of the holder. Then connect the other end of the USB cable to the adapter included in the package and connect it to the 230 V mains. (Figure 3)
Figure 3.
– 13 –

7.2. Putting the receiver unit into operation
To put the receiver into operation, loosen the screws on the bottom of the product without removing them completely, then separate the front panel of the receiver from the back panel. After that, fasten the back plate with the supplied screws to the wall near the boiler. Under the connectors, printed on the electrical panel, there are inscriptions marking the connection points, which are as follows: L N 1 2 3 4 5 6 7 8
NO COM NC
7.2.1. Connecting the controlled device(es) to the receiver unit
The receiver with changeover output controls the boiler (or air conditioner) via a potential-free relay with connection points: NO, COM and NC. The connection points for the room thermostat of the heating or cooling device to be controlled should be connect the terminal block in the rest open state to the NO and COM terminals. (figure 4).
In case the device to be controlled does not have a thermostat connection point, the power supply wire of the device to be controlled must be disconnected and connected to the NO and COM connection points of the thermostat (Figure 5).
ATTENTION! When designing the connections, always take care the load capacity of the receiver and follow the instructions of the manufacturer of the device to be controlled! Leave the wiring to a professional!
The NO and COM connection points close in response to a heating/cooling command from any thermostat. The voltage appearing at these points depends only on the controlled system, therefore the size of the wire used is determined by the type of controlled device. The length of the cable is irrelevant, you can install the receiver next to the boiler or away from it, but do not install it under the boiler cover.
In addition to controlling (switching on/off) the boiler/air conditioner, the receiver is also suitable for opening/ closing the valve(s) of 8 different heating/cooling zones, as well as for controlling a pump. At the connection points of the zone valves, 230 V AC voltage appears on the heating/cooling command of the thermostat belonging to the zone. The zone valves must be connected to points 1, 2, 3, 4, 5, 6, 7 and 8 of the terminal block. A voltage of 230 V AC appears at the connection points of the pump at the heating/cooling command of any thermostat. The pump must be connected to the terminal point.

A COMPUTHERM E800RF vevegység csatlakozóinak méretei max. 2-3 párhuzamosan kapcsolt készülék (zónaszelep, szivattyú, stb.) vezetékeinek fogadására alkalmasak. Ha egy zónakimenethez ennél több készüléket (pl. 4 db zónaszelepet) kíván párhuzamosan csatlakoztatni, akkor azok vezetékeit még a bekötés eltt közösítse és csak a közös vezetéket csatlakoztassa a zónavezérlhöz.
When using slow-acting electrothermal zone valves, if all zone valves are closed in the default position without heating, it is recommended to delay the start of the boiler in order to protect the boiler pump. You can find more information about the delay of the outputs in Chapter 11.7. 7.2.2. Connecting the receiver unit to the mains
The 230 V power supply should be connected to the terminals marked N-L inside the receiver unit with a two-wire cable. This provides power to the receiver, but this voltage does not appear on the output connection points (NO, COM and NC) of the boiler control relay. The neutral wire of the network must be connected to the ,,N” point, while the phase wire must be connected to the ,,L” point. It is not necessary
– 15 –

to pay attention to the phase correctness when connecting the power supply and it is not necessary to connect a ground because the product is double insulated. The grounding point on the electrical panel is not used for grounding the entire receiver, it is only an option for the grounding of the product connected to the receiver to be solved inside the receiver.
7.3. Synchronization of the thermostat and the receiver unit
The two units are syncronized in the factory. The thermostat and its receiver have their own security code, which guarantees the safe operation of the device. If for some reason the thermostat and its receiver unit do not communicate with each other, or if you do not want to use the factory-paired thermostat and receiver together, make the following steps to syncronized the thermostat and the receiver unit:

9. OPERATION OF THE THERMOSTAT
The thermostat controls the device(s) connected to it (e.g. gas boiler, zone valve, pump) on the basis of the temperature measured by itself and currently set, considering the switch sensitivity of the thermostat (±0.2 °C by factory default). This means that if the thermostat is in heating mode, the temperature is set to 22 °C on the thermostat and then at a switching sensitivity of ± 0.2 °C, then at a temperature below 21.8 °C at the output of the receiver for the given zone or the shared the 230 V AC voltage appears on the pump output. At a temperature above 22.2 °C, the 230 V AC voltage is cut off at the output of the receiver unit belonging to the given zone and at the output of the pump. In cooling mode, the receiver switches exactly the opposite way.
The switched-on status of an output of a given zone is indicated by the lighting of the red LED belonging to the given zone on the receiver, as well as the or icon on the device display and in the telephone application according to the selected operating mode.
The boiler and pump control outputs of the device are switched off in the default state (when all thermostats connected to the receiver give the switch-off command). These outputs are turned on when at least one thermostat gives an on command, thereby starting the devices connected to them, and they only turn off when all thermostats send an off signal to the receiver. The switched-on state of these outputs is indicated on the receiver by the lighting of the orange (PUMP) and blue (BOILER) LEDs belonging to these outputs.

Chapter 11.6. Chapter 11.7.

11.1. Selecting the switching sensitivity (DIF) It is possible to set the switching sensitivity. By setting this value, you can specify how much the appliance switches the connected device on/off below/above the set temperature. The lower this value, the more uniform the internal temperature of the room, the greater the comfort will be. The switching sensitivity does not affect the heat loss of the room (building).
– 25 –

In case of higher comfort requirements, the switching sensitivity should be chosen so as to ensure the most constant internal temperature. However, also make sure that the boiler is switched on several times hourly only at low outdoor temperatures (eg -10 °C), as frequent switching off and on will impair the efficiency of the boiler’s operation and increase gas consumption. The switching sensitivity can be set between ±0.1 °C and ±1.0 °C (in 0.1 °C increments). Except some special cases, we recommend setting ±0.1 °C or ± 0.2 °C (factory default setting). See Chapter 9 for more information on switching sensitivity.
11.2. Calibration of the temperature sensor (ADJ) The measuring accuracy of the thermometer of the thermostat is ± 0.5 °C. The temperature displayed by the thermostat can be modified in 0.1 °C increments in comparison to the temperature measured by the temperature sensor, but the modification can not exceed ± 3 °C. 11.3. Antifreezing (FRE) When the antifreezing function of the thermostat is activated, the thermostat will switch on its output, regardless of any other setting, when the temperature measured by the thermostat goes below 5 °C. When the temperature reaches 7 °C, normal operation of the output is restored (according to the set temperature).
11.4. Memorizing ON/OFF status in case of a power failture (PON) By means of the Memorizing Settings function of the thermostat you can select the mode in which the thermostat continues to operate: · 00/OFF: the thermostat turns off and remains turned off until this mode is altered, regardless whether
the thermostat was on or off before the power failure. · 01/ON: the thermostat returns to the same state in which it was before the power failure (default setting)
– 26 –

11.5. Changing between heating or cooling mode (FUN)
You can easily switch between heating (00; factory default) and cooling (01) modes. The connection points NO and COM of the thermostat’s output relay close at a temperatures below the set temperature in heating mode and at temperatures above the set temperature in cooling mode (taking the set switching sensitivity into account).
11.6. Restoring default setting (FAC)
All settings of the thermostat, except for date and time, will be restored to factory setting. To restore factory setting, after selecting FAC setting option and tapping the button several times, switch over the appearing 08 setting to 00. Then tap the button once to restore factory setting.
If you move on by tapping the button and leaving the FAC value at its default value (08) then the device will not return to default setting but save the settings and exits the operation-related settings menu.
11.7. Delay of receiver unit outputs
When designing the heating zones – in order to protect the boiler pump – it is advisable to try to leave at least one heating circuit that is not closed off with an isolation valve (e.g. bathroom circuit). If this is not implemented, it is recommended to delay the boiler and pump control output of the receiver in order to prevent a situation in the heating system where the valves of all heating circuits are closed but a pump is switched on.
In the activated state, if none of the zones are switched on, in order to open the valves belonging to the given zone before starting the pump(s) and the boiler, the output of the boiler control NO-COM and the common pump output of the receiver unit are switched with a 4-minute delay after the activation signal of the first thermostat switch, while the 230 V AC voltage immediately appears on the output belonging to the given zone (e.g.: Z2).
The delay is mainly recommended if the zone valves are opened/closed with slow-acting, electro-thermal actuators, because their opening/closing time is approx. 4 minutes. If at least 1 zone is switched on, the

output delay function does not work for the switch-on signal of additional thermostats. To activate/deactivate the output delay function, press the DELAY BUTTON inside the receiver for approx. 3 seconds. For safety reasons, use a non-conductive device to press the button. The activated status of the output delay function is indicated by the continuously lit purple LED labeled DELAY inside the receiver. If the function is not activated (factory default), the LED labeled DELAY does not light up.
12. SWITCHING BETWEEN ON AND OFF POSITIONS AND MODES OF THE DEVICE
The thermostat has the following 2 positions: · OFF position · ON position
You can switch between off and on positions in the following way: · Using phone application: by tapping the icon. · On the thermostat: tapping the button.
When the thermostat is off, the screen of the devices turns off and in the application POWER-OFF lettering replaces measured and set temperatures, and the relay outputs of the device go into off (open) position. When the thermostat is on, the display of the device illuminates continuously. If you touch the touch buttons or modify the settings of the thermostat with the phone application, the light intensity on the thermostat gets higher for approx. 10 seconds then falls back to basic level. When the thermostat is on, it possesses the following 2 modes of operation:
· Manual mode. · Programmed auto mode.
– 28 –

You can switch between the modes in the following way:

· Using phone application: by touching or icons.

· On the thermostat: touching the button.

The currently selected mode is indicated as follows:

· In the phone application: manual mode by the icon and programmed auto mode by the icon.

· On the thermostat: manual mode by the icon programmed auto mode by one of the following

icons

(according to the current switching scheme) and by the icon.

The two modes are described in detail in the following sub-chapters.

12.1. Manual mode

In manual mode the thermostat maintains a preset temperature until the next intervention. If the room tempe-
rature is lower than that set on the thermostat, the output of the thermostat will switch on. If the room tempe-
rature is higher than that set on the thermostat, the output of the thermostat will switch off. The temperature to be maintained by the thermostat can be specified in 0.5 °C steps (the minimum and maximum values of the adjustable range are 5 °C and 99 °C, respectively).

The currently set temperature can be modified in the following way:

· Using phone application:

with the

icons

moving the slide (groove) on the circular scale,

· On the thermostat: with the buttons.

12.2. Programmed auto mode 12.2.1. Description of the programmed mode Programming means setting of switching times and selection of corresponding temperature values. Any temperature set for a switch will remain in effect until the time of the next switch. Switching times can be specified with an accuracy of 1 minute. Within the temperature range (the minimum and maximum values of the adjus-
– 29 –

table range are 5 °C and 99 °C, respectively) specified in the settings a different temperature can be chosen for each switching time, in 0.5 °C increments. The device can be programmed for a period of one week. In the programmed auto mode the thermostat operates automatically, and cyclically repeats the entered switches every 7 days. The following 3 options are available to program ram the thermostat:
· 5+2 mode: setting 6 switches per day for 5 working days and 2 switches per day for 2 days of the weekend
· 6+1 mode: setting 6 switches per day from Monday till Saturday and 2 switches on Sunday · 7+0 mode: setting 6 switches per day for every day of the week If you do not need all adjustable switches on certain days (e.g. only 4 switches is required on working days), you can eliminate unnecessary switches by setting their time and temperature to the time and temperature of the last switch you want to use.
12.2.2. Description of the steps of programming
· Using phone application: a) To enter programming mode touch the iicon. Then the screen for programming appears on the display. b) The indication of the currently selected programming mode is located at the top of the screen for programming, beside the legend Programing mode. Touching this, you can switch between programming modes as follows:
– 12345,67: 5+2 mode – 123456,7: 6+1 mode – 1234567: 7+0 mode c) Switches belonging to a given programming mode are below the indication of the programming mode. You can modify data (time, temperature) of switches by tapping the value concerned.

d) To complete programming and return to the screen belonging to the thermostat touch the < icon in the upper left corner. Programs that were set earlier can be checked at any time by entering the programming mode again.
· On the thermostat: a) To enter programming mode touch the button for approximately 5 seconds. Then on the display the legend LOOP appears in place of the hour, and the indication belonging to the currently selected programming mode replaces the current day. b) With the buttons choose the preferred programming mode as follows: – for 5+2 mode: 12345 – for 6+1 mode: 123456 – for 7+0 mode: 1234567 Now touch the button again. c) Following this, you can specify or modify various switch times and temperatures as follows: – You can switch between switch times with the button. – With the help of you can switch between data belonging to switch times (temperature, hour value of the time, minute value of the time). – Values are always set by buttons. After the program of weekdays has been set, you can set the program of the days of the weekend. The day and switch being set are shown by the icon flashing on the display. d) Programs that were set earlier can be checked at any time by repeating the steps of programming mode.
Attention! In the interest of logical programming ensure that in programming the times of successive switches succeed each other during the course of the day, i.e. you should specify switches in chronological order.
