Question about Hunter Fan Company 5/1/1 Programmable Thermostat
I set the thermostat to 74 and the furnance will not ignite.
Run a couple of easy checks:
There are generally two wires on a thermostat for heat these days if you use hot water or steam. If so, touch them together. Does the heat come on? If yes, the thermostat is the problem. If not, you've got a problem with the furnace. If more than two wires, for hot air, you can connect them all together for this test. NOTE where wires came from! R is the common heat wire. G is for the fan and W is for the furnace heat call.
Many thermostats today use a battery to close the relay. You should change it at least once yearly. You may still get a display but no relay action when the battery is weak.
If you do not get a response from your heat source, there are other tests...please repost and state what kind of heat you have...oil or gas, hot air, hot water or steam.
