3M-22 Features

PG 23

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 using a heat pump with Aux heat, if

 

the heat pump cannot keep up and/or is

 

defective, remove jumper from position 8 and put

 

jumper on position 6 and the Aux heat will then

 

be your only source of heat. Be sure to restore it

 

to PUMP when the pump is again operational as

 

aux heat is more expensive than pump heat.
