Will the boiler fire if you press the button on the receiver?
Customer: replied 1 month ago.
Sorry what receiver . Managed to get a display on the remote thermostat . The salus controll box by the boiler doesn't flash green to say it's receiving a signal .

Can we arrange a phone call for tomo evening . I'm out early in the morning . But could ring in the evening
Expert:  Andrew Smith replied 1 month ago.
That is the receiver - is there an override button on it to enable the heating to be turned on?
Customer: replied 1 month ago.
No override button . Manual control on boiler but won't fire up off that either
Expert:  Andrew Smith replied 1 month ago.
I can tell you how to wire around it to give you heat until you get it swapped out?

Sounds good to me
Expert:  Andrew Smith replied 1 month ago.
If you take the cover off the receiver and tell me what colour wires go to which connections?
Customer: replied 1 month ago.
Hi .
We have
Black to No
Brown to COM
Brown to L
Blue to N
Expert:  Andrew Smith replied 30 days ago.
L and N provide power to the stat. If you link Com and No under the same connection it will link out the stat
Customer: replied 30 days ago.
Com and normally open bridged . Boiler fires up . Heating on . Put another set of new batteries in the remote stat , and the bastard has lit up . I'll let the house warm up and put ihe wires back and see what happens . Re .getting a signal .
Expert:  Andrew Smith replied 30 days ago.
Ok.
At least you have control back until you decide what you are going to do

Put wires back to original and tried using thermostat . Green light on receiver not lighting up , indicating not receiving a signal . In my mind it's either not transmitting or not receiving . Is it a case of replace both ?
Expert:  Andrew Smith replied 29 days ago.
they come as a pair.
Usually cheaper to buy a pack that's on offer.
