Where does the wire go on a Honeywell thermostat?

Is there a manual thermostat for an RV?
If you’re looking for a simple, manual thermostat to replace an old broken one, Coleman’s Mach Manual option is simple and affordable. However, you won’t be able to pre-program temperatures ahead of time, and since it’s analog rather than digital, it may not work on the newest RV HVAC models.

What can I do with my Honeywell RV thermostat?
I set the AC compressor protection off time down from 5 minutes to 2, adjusted the unit for auto changeover (manual it the default) and set temperature range stops for heating and cooling.

What kind of batteries do you need for an RV thermostat?
For a thermostat to work properly in an RV, it has to be either specially designed to be powered off 12 VDC (most home units use 24 VAC) or by onboard batteries. In the case of the Honeywell FocusPRO 5000, it uses a pair of AAA alkaline. The Hunter we had used AA, and they lasted about a year.
