DEVICE DESCRIPTION

The EU-T-4.1/EU-T-4.2 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

Controller equipment:

• front panel made of glass
• built-in temperature sensor
• batteries

HOW TO INSTALL THE CONTROLLER

The controller should be installed by a qualified electrician.

The EU-T-4.1/EU-T-4.2 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.

In order to insert batteries, remove the back cover.

EU-T-4.1 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.

EU-T-4.2 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.

EU-MW-2 RECEIVER
The EU-T-4.2 regulator communicates with the heating device (or the CH boiler controller) by means of a radio signal sent to the EU-MW-2 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 signalises data reception and goes on during channel change;
• 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.
How to change the communication channel:**
Channel 35 is the default communication channel in the room regulator. The channel may be easily changed (if the current channel is used by other devices). To change the channel, press and hold the channel change button on the receiver for about 10 seconds until the red control light 1 goes on. Next, change the communication channel in the room regulator following the procedure described in the section: Controller functions. The red control light 1 on the receiver should go off.

EXTERNAL TEMPERATURE SENSOR

The EU-T-4.2 room regulator may optionally be equipped with an external temperature sensor. The sensor should be mounted in a shaded place so that it is not affected by the weather conditions. The current temperature reading will be sent to the room regulator every few minutes and it will be displayed on the main screen.
The external sensor communicates with the room regulator via radio signal. Both the room regulator and the external sensor are pre-configured to operate on channel 35, but the user may easily change the channel (if the current channel is used by other devices).

How to change the communication channel:
In order to change the channel, press and hold the channel change button. When the control light on the sensor flashes, the process of channel change has been initiated. Keep holding the button and wait until the light starts flashing again. The number of flashes corresponds to the first digit of the desired channel number. Release the button after the desired number of flashes and press it again to set the second digit of the channel number – the control light flashes quickly twice. Hold the button and wait until the light flashes the desired number of times. When the button is released, the control light flashes twice – the new communication channel has been set.
NOTE: In case of a one-digit channel number (channels 0÷9) set 0 as the first digit.
Example 1:
28 is the desired communication channel. In order to select this channel, set the first digit – 2, and the second digit – 8. Press and hold the channel change button – the control light flashes quickly once – the process of channel change has been initiated. Keep holding the button and wait until the light flashes two more times (the first digit of the channel number – 28).
Release the button and press it again – the control light flashes quickly twice – the process of setting the second digit has been initiated. Keep holding the button and wait until the light flashes 8 times. When the button is released, the control light flashes quickly twice – the new communication channel has been successfully set
Example 2:
7 is the desired communication channel. In order to select this channel, set the first digit – 0, and the second digit – 7. Press and hold the channel change button – the control light flashes quickly once – the process of channel change has been initiated. As the first digit is 0, release the button before the control light flashes again.
Press the button again – the control light flashes quickly twice – the process of setting the second digit has been initiated.
Keep holding the button and wait until the light flashes 7 times (the second digit of the desired number).
When the button is released, the control light flashes quickly twice – the new communication channel has been successfully set.
In case of errors in the channel change process, the control light goes on for about 2 seconds. In such a case the channel will not be changed.
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 – in order to do it, remove the back cover.
2. Connect the two-core cable to appropriate sockets in the regulator or the receiver.
3. In the case of EU-T-4.2. check if the current communication channel selected in the regulator is the same as in the receiver. 35 is the default communication channel in all devices.
   If there is a conflict with other devices using radio communication, it is necessary to select a different channel.

HOW TO USE THE REGULATOR

1. PRINCIPLE OF OPERATION
   The EU-T-4.1/EU-T-4.2 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 buttons until 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.

• The display shows the hours when the comfort temperature applies. In the remaining time period economical temperature applies.
  In order to activate this mode, press one of the 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 (+ – ). 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:
  Example 1 – manual mode activation in Day/night mode

When Weekly control mode is active, the user changes the pre-set temperature by pressing plus/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 button
