The 3M-10 can be used with most 24 volt gas, oil or electric heating and air
conditioning systems, heat pump systems with or without auxiliary heat, Normal 2
Stage systems, Zoned Hot-Water, Zoned Forced air systems, or gas millivolt
heating systems. It cannot be used with 120 volt heating systems or. Ask The
Home Depot for other thermostats to control those systems.
The 3M-10 is digital. You can program your desired Heat
and cool temperature by setting the dial. The unit uses
no harmful mercury.
A 5-minute minimum off time in COOL protects your air
conditioning system from being damaged.
Two "AA" batteries (not included) are used to run the
thermostat in some installation. "C" wire installations can
make batteries last many times longer.
