If you're a HVAC tech please chime in. I have a central air with heat and ac that is on a wi-fi thermostat. I like the convenience that can adjust the setting if needed from my phone or pc. I have a 25 PDVC that I've just installed a programmable thermostat. I used this stove a lot to supplement my central heat. I would like to intall a wi-fi thermostat on it as well but I don't have a common wire from the stove. Can I tap the common wire from my central air?
