Technical Data

Mounting Advise Room Sensors

The Accuracy of the room sensors are influenced by the technical specifications as well as the positioning and the installation type.

During Assembly:

• Seal mounting box (if present).
• Installation type, air draught, heat source, radiation heat or direct sunlight can affect the measurement.
• Building material specific properties of the installation place (brick-, concrete-, partition wall, cavity wall, ...) can affect the measurement. (e.g.: Concrete accepts room temperature variation slower than cavity walls)

Assembly not recommended in...

• Air draught (e.g.: close to windows / doors / fans ...)
• Near heating sources,
• Direct sunlight
• Niches / between furniture / ...

Mounting Advices JOY

Plasterboard boxes shall be covered by wall paper or paint to avoid that the plasterboard box's front rim will be partially visible underneath JOY. Maybe consider using white plasterboard boxes (i.e. Kaiser 9063-77)

If the operating mode (change-over DI) of several devices is to be switched together by one contact, the potential-free 230V input must be used (DI2, only possible with the 230V version). It must be ensured that the same phase is used for jointly switched devices.

Function Description – Controller/Fan Stages

JOY Fancoil 5DO (85..260 V ~)

Controller: PI controller (PWM) & 2-point/3-point controller (configurable)

JOY Fancoil EC AO2DO (85..260 V ~)

Controller: PI controller (PWM) & 2-point/3-point controller (configurable)

JOY Fancoil EC 3AO (24 V ~/=)

Controller: PI controller (0..10 V)

Fan stages (all types)

In automatic mode the fan speed is linked to the controller. The assignment of the fan stage to the control (heating / cooling, only heating, only cooling) is freely selectable. To ensure that the fan motor starts reliably, a period of time can be configured in which the fan starts with maximal value. Using one or more time channels, the fan control have to be set per timechannel and per period. Via the touch surface the user has the option to override the settings of the device every time. When the next time channel starts, the fan speed is set to the configured value. The fan is set to automatic mode when the user changes the occupancy state (occupied/unoccupied).

Heating/ cooling with PI-controller (PWM) (only 5DO and EC AO2DO)

The time response of the PI control loop depends on the control parameters xp for the proportional area and tn for the reset time of the integral range. In case of an error, the P portion immediately changes the position value proportionally to the error variable, while the integral portion takes effect after a certain time. The resulting actuating variable is output as a pulse-width-modulated signal directly to the outputs.

Heating/ cooling with 2-point-/ 3-point-controller (only 5DO and EC AO2DO)

In the case of temperature control, the 2-point controller only knows the switching states heating ON and heating OFF. The 3-point controller also knows the switching state of cooling. Two - and three-point controller work with a hysteresis.

Heating/ cooling with PI-controller (0..10 V) (only EC 3AO)

The time response of the PI control loop depends on the control parameters xp for the proportional area and tn for the reset time of the integral range. In case of an error variable, the P portion immediately changes the position value proportionally to the error variable, while the integral portion takes effect after a certain time. The resulting manipulated variable is output as an analogue 0..10 V signal directly to the outputs.

EC Fan automatic mode with PI-controller (only EC 3AO and EC AO2DO)

(for EC AO2DO with two-point/three-point controller, the temperature range for controlling the 0..10 V EC fan is parameterised separately)

The 0..10 V (0..100%) control of the fan is proportional to the calculated manipulated variable of the PI controller.

i.E.: Calculated actuating variable 65% → Fan control with 6.5 V | Calculated actuating variable 22% → Fan control with 2.2 V

EC Fan manual with PI-controller (only EC 3AO and EC AO2DO)

Up to 5 steps (steps) can be set using the configuration software. The set number of steps is divided linearly to the manipulated variable of 0..100%.

i.E.: Max. steps (stages) = 5 | Stage 1 = 20% | Stage 2 = 40% | Stage 3 = 60% | Stage 4 = 80% | Stage 5 = 100%

Max. steps (stages) = 3 | Stage 1 = 33% | Stage 2 = 66% | Stage 3 = 100%

More detailed information for the configuration of the EnOcean channels can be found in the specification.

There are 20 channels available that can be assigned different functions. A channel can be configured as a receive channel, as a send channel or as a message server (SAB communication). 6 channels can be configured with SAB valve actuator, one of these can be set with the bath function. For the SAB with the bath function, an additional setpoint offset can be set. If SAB valve actuators are learned in, the analogue outputs to the internal controller remain active and can also be used.

Functional Overview SAB

The profiles used are divided into functional groups:

• SRW/SRG: Window contact and window handle. Both have an influence on the window contact function and are linked to the digital inputs or the Modbus default. Up to five sensors can be learned-in.
• VFG: Sensor for changeover control. Only one changeover sensor can be learned in.
• EXT/WRF: Receiving channel: Temperature preset by an external room temperature sensor. Overrides the internal temperature sensor. Max. one sensor can be learned in. An EnOcean room operating unit is displayed on the send channel.
• OCC: Up to 3 motion sensors can be learned in and affect the occupancy function. The last changed value (Modbus, EnOcean, Button) will be accepted. If several EnOcean motion sensors have been learned-in, the "ROOM UNOCCUPIED" value will only be accepted once all sensors have signaled "ROOM UNOCCUPIED".
• KEY: Controls the internal keycard function. When learning a key card switch, the card must not be plugged in AND pulled immediately during the learn-in process. It is necessary to wait at least 5 seconds until the second action is performed with the card. Only then will the switch be assigned as key card switch, otherwise it will be learned in as a radio rocker switch (function group RPS).
• SUP: A superior control unit to override the internal functions.
• SAB (5+1 Bath): Up to 6 SAB's can be learned in. One pcs. can be assigned with the "Bath" function. The other channels can be used optionally for heating or cooling. For each SAB channel, an offset for the setpoint can be configured via Modbus.
• OUT: Only in direction of transmission. A controller status (A5-11-02) every 15 minutes (configurable) and with every change of any value.

Inputs

Up to 2 inputs are configurable for functions such as windows contact, dew point, occupancy, change-over or external sensor option. The overview of possible combinations can be found in the software specification of the JOY.

• Sensor (NTC10K): The value of an external sensor will be shown if connected and configured accordingly. In this case, the room thermostat controls according to the external sensor. Alternatively, an external temperature sensor can be used at the universal input to protect floor heating. If a configured temperature is exceeded, the heating sequence is suspended.
• Change-Over DI: Which controller is active depends on the state of the Change-Over contact. (Factory default: contact open heating controller active, contact closed cooling controller active). The terminals 4 and 5 are used as outputs for heating rsp. cooling.
• Change-Over Sensor: The Change-Over Sensor is used for switching between heating and cooling mode automatically. If the temperature is below 22 ° C, the controller is in cooling mode. If it is above 25 ° C, it is a heating mode. If an input is configured as a change-over, the room thermostat is automatically in 2-pipe operating mode and both outputs (terminals 4 and 5) are used as outputs for heating rsp. cooling.
• Window contact/Energy hold off: If a window contact is enabled via the digital input, the reference will switch to a setback set point (Heat SP/Cool SP).
• Dewpoint: An active dewpoint contact locks the cooling controller.
• Occupancy: If occupancy-function is active, the symbol will be displayed automatically. In state of "unoccupied" the heating set point is reduced by 2K (default setting) rsp. the cooling set point raised by 2K.
• Keycard-Switch: When the card is not inserted, the device is switched in sleep mode. Operation of the keys is locked, the display is switched off and the controller adjusts to the nominal values of the "unoccupied"-State.
• Alarm contact: An alarm symbol can be shown in the header of the display. The backlight flashes when the alarm is active. This symbol is in the same position as the ECO symbol. The alarm symbol has a higher priority and overwrites the ECO symbol!
