You should be able to pull the bottom away from the wall then lift up to disengage the top. Underneath there are screws to take the base off the wall. You will obviously need to remove the wires also, before removing the base. Make sure the label the wires or take a picture so you know how to install the new thermostat.

Manual foe a RCH9300WF


It's pretty basic actually. I've done this with Nest and Honeywell Lyric. The only thing you need to do is removing the current thermostat from the wall and connect the new one.

Set it up using your mobile application and you're good to go.

Remove the batteries and remove the R or RED wire from the thermostat's sub base R/ RED terminal for 1 hour, if this does not work, replace it.

Honeywell thermostat keeps going to "leave" status and increasing the temperature in our house and we can't figure out how to reprogram it to stop

Is the honeywell wv8840B1109 like a smart meter. I was concerned after they installed this on my new water heater. It's basically an alarm for if the pilot shuts off. Seems awfully big to just be for that....


Thanks for photo link. Not a smart meter.
Just ordinary water heater gas control valve, with small circuit board to support error codes:
Copy following link for handy resources:

http://www.thetankatwaterheaterrescue.com/forums/forum3/
http://waterheatertimer.org/How-to-replace-Honeywell-gas-control-valve.html
How the newer gas control valves are different: Old water heater had thermocouple which supplies very tiny current to gas control valve. When pilot light blows out, the thermocouple no longer sends tiny current and gas control valve shuts off gas to heater.
New gas water heaters have thermopile (just like modern furnaces and stoves), which is basically several thermocouples bunched together. So thermopile sends more current to gas control valve, and supplies enough current to power small circuit board. The circuit board records error events and issues simple error codes. If pilot blows out, then thermopile no longer sends current and gas control valve shuts off gas to heater.
Moreover, the new gas control valve can be repaired and replaced without removing from tank. So tank does not have to be drained... saving time and repair cost.

Honeywell WV8840B1109 temp control valve on water heater. Status light @ 4 blinks between 3 seconds indicating "high temperature shutdown" even though lighting pilot with water cold. .


II have exactly the same problem: Honeywell WV8840B1109 temp
control valve on water heater. Pilot is on, but the burner won't
no matter how high I turn the temperature knob. Status light blink
4, which by the controller is "high temperature shutdown" and has
nothing to do with the problem. The real problem is that the
computer chip in the controller has gone bad. Problem is solved by
changing a new gas control valve/thermostat. The old Honeywell
control valve uses pure mechanical stuff and was very reliable,
almost never has a problem. I don't understand why they switch to
this new electrical one which use the tiny voltage generated by
the thermopile to run, easy to break, because of the electric
chips, and is more expensive. The only reason I can think of is
that they want to get more money from our pocket.
