Why not go with a digital mode vs those analog manual slider control types?
Digital heat only roughly $27 at that Canadian Tire website.
And more accurate temp control
Shouldn't need to add an ON/OFF switch. T-stat can be turned OFF
IS old t-stat not working.....or is issue with furnace?
Connecting the two wires together will make furnace run IF t-stat is bad.
If furnace does NOT run when the two wires are connected then Furnace has problem
The furnace runs properly but the thermostat does not control the heat properly, so it is the thermostat that needs replacing for sure.
Don't mind digital, don't need programmable, but mainly trying to get a simple manual thermostat that does not have the bubble level and that works with the two 12v wires.
Some do not have an on-off switch apparently. The old one there now has a switch, but if you leave it "on" and turn the temp right down, and it is colder out than that, the furnace will stay on trying to get the temp up to that lowest number. So I can see from that why you should have an on-off switch.
