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.
OpenTherm – Hot Water
Standard Power Up and Configuration
(1) Please follow steps 1 to 17 from section OpenTherm Power Up and Configuration.
NOTE: Using UP or DOWN, you can choose either TPI (step 2) or SPAN (step 6). Choosing one option excludes the other.
Programming – Automatic Mode
In this mode, user can set the schedules for thermostat (temperature setpoints for specific periods of time). Programmed schedules should use all time periods.
Repeat the process for all time periods.
Landlord Settings
Landlord settings is a pin code protected feature that allows the landlord to set a service reminder on the thermostat that will warn the tenant when the boiler is due its annual service.
Once service mode has become active, the device will lock the set point temperature as set by the installer/landlord. To unlock this device, the landlord needs to be contacted and the boiler serviced.
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.
