Dometic mechanical thermostat

[steilkurve]

Hey all. Would like to upgrade my 2020 Bambi 22FB mechanical furnace thermostat from Dometic by a digital one. Can I do that? If so, any model folks would recommend?

Yes, many people have done that. I went to a big box store and purchase the cheapest digital thermostat I could find. Most are heating/cooling thermostats. Heating only thermostats are not so common, but can be found. You will only use two wires from the furnace that go to the existing thermostat and connect them to the two contacts for heating (follow instructions). Since there is no power provided through these two blue wires you will need to get a digital thermostat that uses AAA batteries for its power source. Or get a non-battery thermostat and tap into the 12v system for power.

ps:
pay attention to the dimension of the new and existing T-stat. You want to make sure to cover the screw holes for the existing.
ps2: make sure the t-stat is rated for at least 14 volts. (most are higher and that is ok)

any home thermostat will work $20-$500
BUT only for the heater. it will not control the roof AC as it has its own proprietary control

Thanks. And would there be any way to control the roof AC through a thermostat as well?

Just to close the loop. I’ve installed a Honeywell battery-powered thermostat. See photo. Works great. Thanks all for the advice.
