Honeywell zw thermostat

[afmiller]

For some Odd reason the thermostat resets it self and screws the date up I think it's causing the furnace to kick on needlessly as well

[Rotech]

Is it battery operated or it has the C wire?

[afmiller]

I'm on c wire

[Rupp]

Sounds to me like the stat could be bad. It shouldn't simply reset itself.

[afmiller]

I've got a suspicion that when it reaches it target temp, it's resetting the screen. It doesn't wipe the info that has been saved but it does boot up again

[afmiller]

That theory was wrong, but it did save the set to temp

[afmiller]

Went to confirm the wiring down at the furnace. Want to mention I don't have ac, only gas


I have Y,C.W,R and an unlabeled screw that connects to the shut off it looks like

The y isn't being used
The w goes to w on the thermostat
The r goes to the rh and rc
I have a green wire in the bundle which isn't being used and connected that to the c on both the block and terminal.

Solved,

Even though it says C, it's not pulling 24v
