HoneywellTH1100DV1000/U Pro 1000 Vertical Non-Programmable Thermostat

Q: Can this be used on a 12v system?

Yes. I am using one on a 12 volt system and 5 on 500 milivolt systems. It should also work on a 24 volt system. It should be noted that this thermostat receives power to run the display and electronics from 2 AAA batteries that last a long time. These are required on a 500 milivolt system. The batteries can be omitted on a 12 or 24 volt system if (and only if) you have a 3 wire connection to the thermostat. The 3rd wire is the common terminal (which is not required for a mechanical thermostat with no clock, light, or electronics). You may use the batteries with a 3 wire system that doesn't need them. I believe this will cause it to hold its setting if the power goes out and comes back on. I believe (but am not sure) that the setting will be lost on a 3 wire system without batteries if the power goes out. On a 500 milivolt system the batteries are required.

Q: Does this work on a gas fireplace with a 2 wire setup?

I am using this thermostat on a 2 wire setup. It works fine. Boba

Q: How do you program this thermostat? (honeywell pro 1000)

There is no programming of this thermostat. It is for heat only.

Q: Does this work for 12v DC furnace for camper/travel trailers?

Yes. I replaced the OEM thermostat that failed the first night in my 2017 Airstream with this exact model TH11000-1000 three years ago and it's worked great ever since. And I had the same model in my little camping trailer as well. Both were 12v propane fired forced air, although that makes no difference since the electronics in this thermostat are separately powered by two AAA batteries and all it has to do is make and break the two-wire heater connection.
