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.

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 pre-
set 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.
