  • green 1 (1)– indicates data reception, goes on during channel change;
  • red (2)– indicates receiver operation;
  • green 2 (3) – goes on when the room temperature fails to reach the pre-set value – the heating device is switched on.

NOTE
In case of communication failure (e.g. when the battery is flat), the receiver automatically disconnects the heating device after 15 minutes.

NOTE
In case of communication failure (e.g. when the battery is flat), the receiver automatically disconnects 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 (4) for about 10 seconds until the  green control light (1) goes on. Next, change the communication channel in the room regulator following the procedure described in part VII.c.7. Confirm with the channel change button. The green light on the receiver should go off.

External temperature sensor

EU-292v2 room regulator may optionally be equipped with an external temperature sensor. The ensor should be mounted in a shaded place so that it is not affected by the weather conditions.
The current temperature value 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).

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. Hold 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. Hold 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. Hold 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 ca. 2 seconds. In such a case the channel will not be changed.

First start-up

EU-292 v2:
In order for the controller to operate correctly, the user must follow these steps when starting the device for the first time:

  1. Remove the front cover of the controller and insert the batteries.
  2. If the room regulator is to control the underfloor heating system, connect the additional sensor to the floor sensor contact.
  3. In the case of EU-292v2 connect the two-core cable to appropriate sockets in the receiver.
  4. 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, the user needs to select a  different channel.

EU-292 v3:
In order for the controller to operate correctly, the user must follow these steps when starting the device for the first time:

  1. Remove the front cover of the controller and insert the batteries.
  2. If the room regulator is to control the underfloor heating system, connect the additional sensor to the floor sensor contact.
  3. Connect the controller to the heating device using a two-core cable.

NOTE
One zone may only have one room regulator assigned to it. If more room regulators are assigned to one zone, the external controller will not work properly.

VII. How to use the controller

VII.a) Principle of operation
The main task of EU-292 room regulator is to maintain the pre-set temperature of the room by sending a signal to the heating/cooling device (contact opening) when the desired temperature is reached. In such a situation, the heating/cooling device is switched  off (if the regulator is connected to the CH boiler controller, the CH boiler enters sustain mode).
If the regulator is used in heating mode, it may cooperate with the underfloor heating sensor.
In such a case, the contact remains closed when the floor temperature is below the minimum threshold. After the threshold value has been reached, the contact remains closed until the preset room temperature is reached. If the floor sensor temperature exceeds the maximum value, the regulator opens the contact regardless of the current room temperature.

NOTE
In order for the underfloor heating functions to be available in the controller menu, it is necessary to connect an additional sensor to the floor sensor contact.

VII.b) Operation modes
The user has three operation modes to choose from:

  • 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 EXIT button until day/night mode icon appears on the main screen.

VII.c.6) Optimum start
Optimum start is an intelligent system controlling the heating/cooling process. It involves constant monitoring of the heating/cooling system efficiency and using the information to activate the heating/cooling process in advance in order to reach the pre-set  temperatures.
The system requires no user intervention. It precisely reacts to any changes that affect the efficiency of the heating system. If, for example, some changes have been introduced to the heating system and the house heats up faster than before, the Optimum start  system will recognize the changes at the next pre-programmed temperature change (from comfort to economical) and in the next cycle the heating system activation will be adequately delayed,reducing the time needed to reach the desired temperature.

VII.c.11) Floor temperature hysteresis
Floor temperature hysteresis defines the floor temperature tolerance in order to prevent undesired oscillation in case of small temperature fluctuation within the range of 0,4 ÷ 5°C. This parameter concerns both the maximum and the minimum floor  temperature.

Example:
Maximum floor temperature = 45°C
Hysteresis = 2°C
Minimum floor temperature = 30⁰C

The room regulator disables the contact when the temperature of 45⁰C on the floor sensor is exceeded. When the temperature starts falling, the contact is activated again at the temperature of 43⁰C on the floor sensor (unless the pre-set room temperature has  been reached).
With the minimum floor temperature the hysteresis function works the other way round. After the value of 30⁰C has been reached on the floor sensor, contact opening/closing depends only on the current room temperature (reaching this value opens the  contact). When the floor sensor temperature drops to 28⁰C the contact closes regardless of the current room temperature.
