Hi Rjmmoon: I took a look and the thermostat does not have wires to it for a 24v connection. This heat source (propane with pilot light) was designed to still work in the event of a power failure. So it operates soley on batteries. But I believe the new comcast digital thermostat can be hard wired with a 24v system? If so, please let me know what I need to buy and where I can find instructions. You mentioned a 24v plug-in transformer?
Thanks!!!
