TT Thermostat

[imscott]

Hello everyone, I am new to the forum and sorry if this has been covered already. I have a Rockwood Mini-Lite 1905 with a Suburban heating/cooling thermostat and want to change it out with a digital one. Any suggestions?

Any battery type will work , such as Honeywell, or even hunter. You should be able to get it at Lowe's for about 21 bucks.

Easy to do. These links might help:

I'm not sure you can just replace it with any ole digital thermostat.
Tell us the model of your existing thermostat and/or post a picture of it.

X2. I replaced the analog Suburban in my Roo 19 with a Honeywell RTH111B. It only controlled the furnace. I also replaced the Coleman-Mach in my Mini Lite with a Honeywell RTH111B; it controlled both furnace and ducted AC. They also make a programmable version, Model #RTH221.

If your AC is controlled by the T-stat (as opposed to ceiling controls) your AC probably has 2 fans speeds, but the Honeywell only handles one speed, so you have to either add a switch to chose fan speed or just pick one speed.

Note they DO make a plug and play digital version of the Coleman-Mach for about $50-60, Comes in black and white:

The Honeywell is about $25.

Coleman Mach to Honeywell wiring diagram attached. For Suburban furnace only, you'd only have two wires, red and white.

See post #11 here for more info (Note the PDF here is a newer version of the one in the link - new one sort of shows you what the T-stat is actually doing):
