Hi,
We recently bought a new house which has a Vaillant boiler which uses a HCW80 thermostat and a HC60NG relay module.
However after we took the batteries out of the HCW80 and replaced them we have been unable to get thermostat to communicate with the HC60NG.
I have followed the instruction as follows:
1. Press the teach button on the HC60NG for 15sec until the red light flashes.
2. Press the teach button on the HCW80
As soon as I do this the light stops flashing on the HC60NG but when I move the dial on the HCW80 nothing happens?
Should the red light be on, on the HCW80? The light only comes on when I press the send button?
Can someone please help?
Thanks
