But, for the furnaces itís another story. I canít start one of them and the one I can start itís kind of hard to have an accurate control of the unit. The receiver on the furnace doesnít seem to receive the signal every time from the remote control. Sometimes you have to give it quite a few tries before itís start or stop. Also, if youíre to close to the air conditioning unit while trying to start the furnace it may interfere with it. Very confusing. Finally, there seems to be no adjustments possible for the force of the fan. On the remote it says high, medium or low but itís on high all the time, canít be change.
Iím thinking about having a wall thermostat installed. Anyone has another solution?
I only have one furnace and it's controlled by a wall mounted t-stat. Propane gas furnaces have limits and safety devices that keep it from an immediate response.
When you turn it on the Inducer Motor runs first to bring in combustion air as well as exhaust air. If the pressures are fine from no obstructions then the ignitor will click to ignite and open the gas valve.
When you manually shut down the unit or it reaches the temperature set, the gas valve will close but the fan will continue to run until the exhaust temperature is down to a safe temperature at which time the exhaust fan will shut off.
As for remote controls on the AC and Furnace the function of the equipment should be the same.
