Smart and wi-fi enabled thermostats can be used with most heat pump systems. In order to verify that your heating system will function with a new smart or wi-fi enabled thermostat, please view the compatibility checker listed in the “specifications” section of each smart thermostat, or visit the manufacturer website for more information 

Currently, thermostat inventory is limited and available on a first come, first serve basis. Please allow 1-3 weeks for shipping.
