Remote Thermostat Control

Heat Pump Models

The Zoneline® 6100 Series heat pump units may be connected to a single-stage cooling/two-stage heating thermostat designed for use with heat pump systems. GE offers two thermostats compatible with the

6100 series units:

	connection wires.

Please see page 55 for installation recommendations for the remote thermostat wiring. Compatibility of other thermostats considered for use with the GE Zoneline unit is the responsibility of the customer.

The control voltage on the remote control conductors is 24 VAC.

The remote thermostat-Class 2 option (Mode 6 in the auxiliary control setting) must be turned ON to enable remote thermostat control. Refer to installation instructions packaged with the chassis.

The fan speed for the 6100 Series in remote thermostat operation is selected by the connection of the fan wire from the thermostat to either the HIGH or LOW terminal on the unit. See the sketch of the unit terminals for the location of the HIGH and LOW fan speed terminals. Operating the unit in low fan speed reduces the operating sound level of the unit.

When connected to a remote thermostat, the indoor-air- temperature sensing is shifted from the unit to the remote thermostat. For this reason, the units will operate slightly differently when connected to a remote thermostat. The above chart shows the unit operation when connected to a remote thermostat.

Boost heat option should not be used with remote thermostat operation since this will cause the unit to switch to resistance heat when outdoor temperatures are below 46ºF.
