Remote Thermostat Control; Resistance Heat Models - GE 2900 Series Product Manual

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 2900, 900 and 5800 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 2900 resistance heat units may be connected to
a single-stage thermostat designed for use with cooling with
electric heat systems. GE offers three thermostats
compatible with the 2900 Series unit.

The Class 2 Mode Switch (dip switch #4 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 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 2900 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.

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.
