[GORDON HUMMEL]

I actually have 3 different thermostats, 2 have different setting for the week & weekend. The last one I installed a Honeywell, RTH111 just has 4 different time setting. This works fine as now that I'm retired everyday is saturday & it's easier to program.
All 3 work the heat & air.
As far as wiring goes, it used the same 5 wire's that the Dometic thermostat used. I do see I made a note that the blue wire goes to the post labeled yellow. the other 4 are the same colors.
Last & most importantly, these new thermostats come with an AC compressor delay circuit. The dometic delays the compressor activation for 3-5 minutes after cooling is called for. This is to prevent short cycling damage to the compressor. I have bypassed the timer in the Dometic control box & now it comes on immediately.
NOTE: This last change will not protect the compressor is case of power failures/change over which is more common in coaches than houses!
