yes it is
Expert:  BillyHvac replied 1 year ago.
what is the model number of the thermostat? It will have to be "told" what it is controlling.
It could be gas furnace, heat pump, electric furnace, boiler etc....we have to tell the thermostat what it is controlling

Expert:  BillyHvac replied 1 year ago.
thank yu...in the install manual there will be set up instructions...whether it is a switch on back that needs flipped or a menu to program.
There will be some way to tell it what to do. There are many BesTechs...or I would look it up and see how to program
