On the front of the receiver’s housing there
is an ON/OFF switch and two indication
diodes.
Green diode lights up, when the receiver
receives a signal from a transmitter with
a heat demand.
Red diode lights up, when receiver is
connected to the 230V AC power supply
and the switch is in ON position.

NOTE: Always isolate the AC Mains supply before installing
or working on any components that require 230 V AC 50Hz supply.
The assembly should be carried out by a person having appropriate
electric permissions. Incorrect wires connection can damage
the device.
Communication code change is done by DIP switches (numbered 1-5).
Set the DIP switches on the receiver in random positions.
To check if the devices have been paired correctly, set the
thermostat knob to the maximum. Red led diode will light up
on the thermostat and heating signal will be sent. If the green
LED lights up on the receiver it means that the devices are paired
correctly.
Set the receiver’s switch to the ON position - red LED diode on the
receiver will start to ash.
Press and hold for 3 seconds SYNC button located on the back of the
thermostat.Thermostat’s red LED diode will start ashing.
If the LED diode on the receiver stops ashing, it means that the
pairing process was successful.
To nish the pairing process, press and hold SYNC button again.
LED diode on the thermostat will stop ashing.
The ERT20RF thermostat is factory-adjusted to work with a heating device
(heating mode), however, there is a possibility to switch it to cooling mode,
so it can work also with a cooling device.
To change heating/cooling mode, change the position of the jumper on the
back of the thermostat, as shown in the gure below:

COMMUNICATION CODE CHANGE
NOTE: To avoid interference caused by other wireless devices, it is
strongly recommended to change the communication code for other
than factory.
