Selector Switches

In order for this Climate Technology thermostat to control your system, the system type must be specified by selector switch on the rear inside if the thermostat. There are also other selector switches that allow you to customize the features to suit your needs. Refer to Figure 2 for removal of wallplate.

NOTE: When changing these features after installation, move the power switch to OFF before removing the thermostat from the wall.

System Selector Switches:

■Heat Pump or Multi-Stage selector (HP-MS switch)

The factory position for this switch is in the “HP” position. Leave it in this position if you have a heat pump system or need emergency heat control.

If you have a conventional multi-stage system (more than 1 stage of heat or cool), then slide the switch to the “MS” position.

NOTE: The Emergency Heat Function operates both stages of heat at the same time when in multi-stage mode.

Selector Switches (continued)

■Heating system selector (HG - HE switch)

The factory position for this switch is in the “HG” position. Leave it in this position if you have a gas furnace or an oil burner.

If you have an electric furnace, test to see whether the Heat and Fan come on as expected.

If Fan operation is normal, leave the switch in the “HG” position.

If the Fan does not come on within a minute of the thermo- stat calling for Heat, change the switch position to “HE.”

This selector has no effect in the cooling mode.

NOTE: “HG” position is for gas and most other systems. “HE” position is for certain electric systems having a fan relay.

NOTE: This option is ignored when heat pump (HP) sys- tem is selected.

■Low Battery Warning Selector

This Climate Technology thermostat operates on your system’s 24V AC supply. Two AAA batteries may be installed to provide clock operation and program retention during power outages.

The factory position for this switch has the Low Battery Warn- ing Enabled. If the thermostat is to be used without batteries,

the switch can be moved to Disable. In this position, the Low Battery Warning will not be displayed.
