Depending on the thermostat re- quired or selected, air handlers may utilize four to six low volt intercon- necting wires between the indoor unit, thermostat and outdoor unit.

Some thermostats do not require the use of the “C” (brown) connec- tion. In this case, ensure that any unused wires are insulated with a wire nut to prevent them from mak- ing contact with the junction box or other metal surfaces.

If the indoor unit has electric heat then a “W” connection is required be-

tween the thermostat and indoor unit.

Note: If the control is con- figured for unit mount con- trol do NOT connect a wall thermostat to the unit.

•Some thermostats do not require the use of the “C” (brown) con- nection.

•Heat pump operation requires the connection of the “O” (or- ange) terminal from the outdoor unit to the thermostat.

The reversing valve is energized in the cooling mode for EMI models S1H heat pump condensers.

Ensure that any unused wires are insulated with a wire nut to prevent contact with the junction box or other metal surfaces.

Once certain all electrical connetions are made replace control box cover.

Single-Zone Heat pumps Only Two- stage heating requires the combination of a heat pump condenser and an indoor unit that is equipped with an electric strip heater. The indoor electric heater will energize as the second stage heat source (the tem- perature is dependent on the thermostat selected) and also during the defrost mode for models S1HA.
