Remote Thermostat Control

In some installations, control of the operation of the unit at a location remote to the unit itself may be desired. Unit mounting locations (high in the wall or over a transom) resulting in inaccessible unit mounted controls can be connected to a remote thermostat. Other installations may use remote thermostat control for design or performance enhancement. The unit is

connected to the thermostat by low voltage wiring, which permits the operation of the unit to be selected and the temperature to be sensed at the thermostat.

All Zoneline 2500, 3500 and 5500 Series units are adaptable to Class 2 remote low voltage thermostat. The only additional field supplied components are the remote thermostat and wiring necessary to connect it.

The controls on the unit are not functional when the remote control function is used.

Resistance Heat Models

The Zoneline 2500 resistance heat units may be connected to a single-stage thermostat designed for use with cooling with electric heat systems. GE offers 3 thermostats compatible with the 2500 series unit.

The Class 2 Mode Switch (dip switch 12 on the auxiliary control board) must be set to the ON/UP mode to enable remote thermostat control. Refer to installation instructions packaged with the chassis.

Please see page 57 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 units may not be compatible with some solid state thermostats.

The fan speed for the 2500 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 in low fan speed reduces the operating sound level of the unit.

Freeze SentinelTM remains operational if the unit is connected to a remote thermostat. The unit may be connected to a Central Desk Control (CDC) system and controlled with a remote thermostat when the CDC system has the unit in an operational status. See page 14 for additional information on the CDC system.
