Like the other poster stated, you will have to use a thermostat with an equipment interface module like some of the honeywell thermostats if you only have 2 wires. That will require running new wires from the equipment to the module and the knowledge to wire them properly. That is your only option without running new a thermostat wire bundle. If you get 24 volts ac between any two wires then one of the wires is common.
If there is not a common wire running up to the thermostat then you can join any two of the wires together and see what happens when you join the two wires together. Unscrew the two wires from the terminals. Remove the motherboard of the old 2 wire thermostat and put the new 2 wire thermostat in its place. Reconnect the red and white wire, tighten down the set screw, and put the control panel back on. If the unit requires only two wires, the system is only able to heat the space. If any cooling, like an air conditioner or fan control, is required, more wires are needed. 4. 7 out of 5 stars 2,409. $37. 00 $ 37. Get it as soon as tue, jul 12.
