Earl, the only negative about using a digital one, is the parasitic drain you are creating, they add up after one here one there.

I have solar so my batteries are always getting a trinkle charge. I'm guess the light on the digital thermostat may go out after a few seconds or not. I think when I turn the batteries off the thermostat is off too.

I thought you meant the thermostat would drain my trailer batteries. I believe the thermostat are 12v?

When there is a call for heat, the switch closes which connects the two wires from the furnace to the thermostat together. The mechanical type uses a mercury switch and no power at all. The digital type uses two AA batteries to drive the display and control board. |

I've been watching this post with interest...
I'd like to have a heat/cool thermostat in my 231VRL that will replace the existing analog heating TStat like Earle but I also want to control my Coleman-Mack dial-controlled air conditioner in the roof.

I actually would not know about that, if yours uses batteries, then of course there is no drain, but mine has two wires feed to it and no batteries, so I speak of only those that have no batteries. I bought mine at Loews and perhaps if I knew one ran on batteries, I might have gone that route, but how is the signal sent to the heater? |

There are two wires coming from the heater. To call for heat, the thermostat connects those two wires together. When the temperature is above the setpoint of the thermostat, the thermostat breaks the connection between those two wires to turn the heat of. |

To replace a HEAT ONLY thermostat consider Honeywell TH1100DV1000/U Pro 1000 Vertical Non-Programmable Thermostat or Honeywell TH1110D2009 Non-programmable heat only.

Iy would be nice to have a programmable thermostat for the A/C, but all I have is the manual controls on the ceiling on the unit itself. Every time we leave for several hours I always turn the A/C off and when we come back it's 95 degrees in the trailer and takes an hour or so to cool down. Someone on this site said they replaced their A/C with a better unit that came with a remote control which would be nice to have. They said they bought the new A/C for like $1100 and sold the old one for $700 or something close to those numbers. I would love to have a A/C with a programmable thermostat so I can set it at a higher temp so when I come back it's not so hot.
