I connected the old roomstat back up to the boiler, the old roomstat is still located in the same place, I tried installing a salus st620wbc the receiver was picking up the wireless programmer but in was not firing the boiler up.
My grandad as purchased a Salus st620wbc for is Worcester Bosch 30 cdi boiler has he want to move the thermostat to a different room so he's decided to go wireless.
Today I tried installing the thermostat on the boiler everything was going fine until I tested it and the receiver was lighting...
