Thermostat issues

[Mace Canute]

Funny thing, I just had a new Modine unit heater installed. When connected to the electronic thermostat I used for years on my old GE furnace, it would keep the temperature at 20 degrees instead of the 10 degrees that it was set for. I switched to an old mechanical mercury switch T87 Honeywell and all is good. The electronic thermostat only had two terminal points so I definitely didn't connect it wrong the the unit heater only shows two terminals to connect the thermostat to. Weird, eh?

Don't forget, in most cases you can use a 110, 220, or 347v thermostat on 24 volts. It only has to break the circuit.
If your heater has a mechanical t'stat with a 24v circuit in it, you may have to break into that circuit and add another t'stat in series.

Never even thought of that... I am also thinking that for $25 I can get that nice digital one posted above and even be able to have it programed! Seems like the way to go maybe.
I appreciate all the help
