Receiver Wiring
Step 1. Identify cables
If you are installing your first thermostat, please open the boiler door and
refer to your boiler manual to identify wiring terminals.
If you have existing thermostat or receiver wiring from your boiler directly,
removing the cover of them and taking a picture of cable connections. The
same terminal name may represent different functions in different brands,
please refer to their manual to identify the cables of the corresponding
terminals. After that, disconnect the wiring and remove your old
thermostat/receiver.
