Yes, in most case it can. The 3M Filtrete programmable thermostats are compatible with low voltage (mili-volt to 24 volt) whole house residential systems. The current wiring on your existing thermostat will be used with the new thermostat. Some models are made to be compatible with line voltage heating systems like wall or baseboard heaters. See compatibility chart for details.
