Vegas Coleman-Mach Thermostat

[RichRob]

It’s not often that I RV in cold weather that requires I use the RV’s heating system, just several days a year. Most often I use an electric spaced heater to get the chill out, and not on while sleeping. But when I do use the system, I find the thermostat not controlling the heat as set. For example, last night I set the thermostat a little below the 70 mark, approximately at 68, but the temperature in bedroom area was anywhere between 58 and 62. The heat came on, brought the temp up a few degrees, then went off for awhile before coming back on an hour or so later, when room temp was back down to 58-62. Is anyone else having this problem? Has anyone switched out the thermostat?

This is the common digital replacement for Thor RVs with Coleman
It’s dual purpose and controls your furnace as well
The thermostat will function much more accurately

I paid less, so shop around.
Also comes in Black

Thank you for the information. When installing this thermostat, will it match-up to the spot the present thermostat occupies? The walls are so thin, I hate to turn them into a pin cushion with new holes. Also is it difficult to install? I am far from being called a handy person.

thermo uses the same holes if I recall
instructions will match-up the wires for you
very ez, plug and play.

Same mounting holes and (almost certainly) identical wiring - color matched. Very easy upgrade I’ve done several now. Maybe the current environment has resulted in higher prices but it seems to me the last one I bought was under $50! Comes in black too.

One of the first things I changed!! You won’t be sorry. As said earlier color match to the old. Snap a pic of the old wire connections and just match them up.

This is getting crazy. I bought one a year ago for under $50!

I got one last week for $77. Installed it this morning. Took about fifteen minutes. Two suggestions:

1. Take a few pictures of all the wiring connections of the OLD thermostat before starting
2. Disconnect old 'stat ONE WIRE AT A TIME and connect the new 'stat using the same wire color as the old one

You can do the same with a $24.00 Honeywell from HD. Just did mine this summer. Youtube is your friend. I used the programmable to get the backlight. This is the second one I have done.

Finally getting around to installing this thermostat. Found a grey wire that does not match-up. Called Honeywell support, and was told that the grey was for low fan speed and the green is for high fan speed, and I could only use one. What did you do? Is there a big difference?

Use high fan speed unless you want to install a separate speed selector switch with a SPDT switch.
