Remote Thermostat Control

In some installations, control of the operation of the unit at a location remote from the unit itself may be desired. A unit mounted high in the wall or over a door, for instance, where the unit-mounted controls are inaccessible, can be connected to a wall-mounted 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 sensed at the thermostat.

Important Notes: Remote thermostat wiring should not be run through wall case. Thermostat wiring should exit the wall below the unit and enter the unit between room cabinet and chassis. Wire molding may be used to hide thermostat wiring. If a sub-base is used, the thermostat wiring may be concealed by the sub-base. Thermostat wiring should not be run parallel to line voltage wires since induced current may cause erratic operation.

All Zoneline 4100 and 6100 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 4100 resistance heat units may be connected to a single-stage thermostat designed for use with cooling with electric heat systems. GE offers two thermostats compatible with the 4100 Series unit.

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.

Please see page 55 for installation recommendations for the remote thermostat wiring.

Compatibility of other thermostats considered for use with GE Zoneline units is the responsibility of the customer. The control voltage on the remote control conductors is 24 volts AC. The AC voltage may not be compatible with some solid-state thermostats.

The fan speed for the 4100 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 below 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.

Freeze Sentinel™ and Heat Sentinal remain 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 operation. See page 14 for additional information on the CDC system.

Unit temperature limiting settings are not functional when unit is connected to a remote thermostat.

When a Zoneline unit is using a remote thermostat control, the RAK806 Universal

Control Cover Label is recommended. The

RAK806 is only available in a package of 10 labels.

The label is placed over the control panel to direct the user to

the wall thermostat for operation of the Zoneline unit.
