need to replace thermostat help Discussion Threadneed to replace thermostat help Electrical Advice
Hi, cm921 honeywell thermostat is old and need a new one so i ordered a new replacement (picture below). This new one i bought which is coming tomorrow has a receiver not sure if I have to wire it up but I assume i have to, its hannicks brand but ill see if it can pair with honeywell maybe it does idk, so I was thinking if I won't be needing the wired honeywell receiver at the boiler I can just make sure theres no voltage running through it by turning off cb and testing with my fluke pen (i know I will be buying a 2 pole voltage and cont' tester soon) and replace it with the new one?
also if I had to isolate the honeywell receiver, Do i need to trail the wires back into the boiler and disconnect them? or just tape off the ends
I will drop some pictures below
