This thermostat can be used with all millivolt and 24VAC heating and cooling
systems. It cannot be used with line voltage systems. This thermostat is digital
and your desired heat or cool temperatures can easily be set on the large
screen with the +/- buttons on the front. A minimum 4 minute off time protects
heating and cooling systems from damage.
This thermostat uses a new technique
called sequential staging for more
comfort with faster reaction to requested
temperature changes when controlling 2
stage systems.
3M-22 Features
If you have a heat pump with auxiliary heat, and the heat pump is not
working properly, your thermostat will still keep your room temperature
within about 2F of the target temperature.
•To select Auxiliary ONLY heat by temporally moving the HEAT PUMP
[Jumper 8] jumper to the HP-AUX ONLY position [Jumper 6]. This will keep
your room temperature within the swing setting of the target temperature.
•Be sure to restore it to PUMP when the pump is again operational as aux
heat is more expensive than pump heat.
