FIRST START-UP
In order for the EU-293v3 controller 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 front cover (battery-powered version).
2.
If the room regulator is to control the floor heating system, connect an additional sensor to the floor sensor
connector.
3.
Connect the regulator with the heating device using a two-core cable.
NOTE
Only one room regulator may be assigned to each zone. Assigning more than one room regulator will
make it impossible for the external controller to work properly.

HOW TO USE THE CONTROLLER
1.
PRINCIPLE OF OPERATION
The EU-293v3 room regulator is designed to maintain the pre-set room temperature by sending a signal to the
heating/cooling device (contact opening) when the pre- set room temperature has been reached. After receiving such a
signal, the heating/cooling device is disabled (if it is connected to a CH boiler controller, the CH boiler switches to sustain
mode after receiving the signal).
If the regulator is used in heating mode, it may also cooperate with a floor sensor. In such a situation, the contact remains
closed when the floor temperature is below the minimum threshold. After the threshold temperature has been exceeded,
the contact remains closed until the pre-set room temperature is reached. If the floor sensor temperature exceeds the
maximum value, the controller will open the contact regardless of the current room temperature.
