II. DEVICE DESCRIPTION

The EU-T-4.1N/EU-T-4.2N room regulator is intended for controlling the heating device (e.g. gas, oil or electric boiler or the boiler controller). Its main task is to maintain the pre-set temperature in the flat by sending a signal to the heating/cooling device (contact opening) when the desired temperature is reached.

Advanced software enables the regulator to fulfil a wide range of functions:

• Maintaining the pre-set room temperature
• Manual mode
• Day/night program
• Weekly control
• Optimum Start
• Heating/cooling
• Button lock
• Automatic manual mode

Controller equipment:

• Front panel made of glass
• Built-in temperature sensor
• Batteries

Regulator versions:

• EU-T-4.1N - wired version
• EU-T-4.2N – wireless version (regulator + receiver EU-MW-3)

III. HOW TO INSTALL THE CONTROLLER

The controller should be installed by a qualified electrician.

The EU-T-4.1N/EU-T-4.2N regulator may be put in any place (1) or used as a wall-mountable panel (2).

1) The regulator may be supported with a stand which should be attached to the back cover.

2) In order to hang the regulator on the wall, remove the stand carefully.

To insert batteries, remove the back cover.

1. EU-T-4.1N CONNECTION DIAGRAM

The room regulator should be connected to the heating device or the CH boiler controller with the use of a two-core cable. The diagram below illustrates how to connect the devices.

WARNING: If pump manufacturer requires an external main switch, power supply fuse or additional residual current device selective for distorted currents, it is recommended not to connect pumps directly to pump control outputs. To avoid damaging the device, an additional safety circuit must be used between the regulator and the pump. The manufacturer recommends the ZP-01 pump adapter, which must be purchased separately.

2. EU-T-4.2N CONNECTION DIAGRAM

In the case of wireless connection, use the above diagrams - a two-core communication cable should be connected to appropriate ports in the receiver.

IV. EU-MW-3 RECEIVER

The EU-T-4.2N regulator communicates with the heating device (or the CH boiler controller) by means of a radio signal sent to the EU-MW-3 receiver. Such a receiver is connected to the heating device (or the CH boiler controller) by means of a two-core cable, and communicates with the room regulator using a radio signal.

The receiver has three control lights:

• Red control light 1 – it signals data reception;
• Red control light 2 – indicates receiver operation;
• Red control light 3 – goes on when the room temperature fails to reach the pre-set value – the heating device is switched on.

NOTE: In case of no communication (e.g. due to discharged battery), the receiver automatically disables the heating device after 15 minutes.

Registration of the EU-MW-3 receiver:

1. Press the registration button on the EU-MW-3 receiver.
2. In order to register the relays, select the "Reg" function in the Menu of the regulator and hold the [Menu Button] or press one of the [Up/Down Buttons]. The message "Scs" means that the registration was successful, while a registration error is signalled with the message "Err". In both cases, the registration can be continued by pressing any button (except [Exit Button]).

The number of registered relays is displayed on the screen. If the regulator has 6 registered relays (maximum number), it is possible to unregister them and the "Del" message is displayed. Using one of the [Up/Down Buttons], select the appropriate option "yes" or "no" depending on whether you want to unregister the relay or not.

V. FIRST START-UP

In order for the regulator to operate correctly, follow these steps when starting the device for the first time:

1. Insert the batteries - to do this, remove the back cover.
2. Connect the two-core cable to appropriate sockets in the regulator or the receiver.

VI. HOW TO USE THE REGULATOR

1. PRINCIPLE OF OPERATION

The EU-T-4.1N/EU-T-4.2N room regulator is designed to maintain the pre-set room temperature by sending a signal to the heating device (contact opening) when the pre-set room temperature has been reached. After receiving such a signal, the heating device is disabled (if it is connected to a CH boiler controller, the CH boiler switches to sustain mode after receiving the signal).

2. OPERATION MODES

The room regulator may operate in one of the following operation modes:

• Day/night mode

  In this mode, the pre-set temperature value depends on the current time of the day. The user may set different temperature values for the daytime and nighttime (comfort temperature and economical temperature) as well as define the exact time of entering day mode and night mode.

  In order to activate this mode, press one of the [Up/Down Buttons] until the [Day/Night Mode Icon] appears on the main screen.

• Weekly control

  This mode enables the user to define the time when the pre-set comfort temperature and the pre-set economical temperature will apply. The user may set 9 different programs divided into three groups:

  • PROGRAMS 1-3: daily temperature values are set for all days of the week;
  • PROGRAMS 4-6: daily temperature values are set separately for the weekdays (Monday-Friday) and for the weekend (Saturday-Sunday);
  • PROGRAMS 7-9: daily temperature values are set for each day of the week separately.

  In order to activate this mode, press one of the [Up/Down Buttons] until a [Weekly Control Icon] appears on the main screen.

• Manual mode

  In this mode, the pre-set temperature is adjusted manually from the main screen view with the use of plus/minus buttons ([Plus Button]/[Minus Button]). Manual mode is activated automatically when one of these buttons is pressed. Once the manual mode is activated, the previous operation mode enters sleep mode until the next pre-programmed temperature change. Manual mode may be deactivated by pressing one of these buttons: [Up Button] or [Down Button].

  When Day/night mode is active, the user changes the pre-set temperature by pressing [Plus Button]/[Minus Button], which automatically activates manual mode. The controller returns to Day/night mode when daytime changes into nighttime (or the other way round) or when the user presses one of the [Up/Down Buttons].

  When Weekly control mode is active, the user changes the pre-set temperature by pressing [Plus Button]/[Minus Button], which automatically activates manual mode. The controller returns to Weekly control mode when, according to the weekly schedule, daytime changes into nighttime (or the other way round) or when the user presses one of the [Up/Down Buttons].
