OpenTherm Power Up and Configuration

OpenTherm Modulating Control is a method of control used by modern heating systems. Instead of switching a boiler on and off at intervals, modulating control allows the amount of heat provided by the boiler to be controlled to match the varying demand from the thermostat. This means the customer has greater system efficiency, energy saving and room comfort from our heating controls.

Please make the receiver connections and power the receiver before inserting the batteries into the thermostat.

RT520TX Thermostat Pairing with the Receiver

If you are using the RT520RF pack, the pairing between the thermostat and the receiver is already done

During the pairing process, please make sure the thermostat and the receiver are at least 1 meter from each other.

If you bought the RT520TX and RXRT520 separately or if you want to re-pair thermostat with the receiver, make sure that the device is disconnected from the power supply and the switches on the receiver have been set to AUTO and ON. Then connect the receiver to the power supply and wait for the red LED to light steadily. Then switch to the OFF position and again to ON position quickly. The red flashing LED will confirm entering the pairing mode.
