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: 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 2800 and 3800 series units are
adaptable to class 2 remote low-voltage
thermostats. The only additional fi eld-supplied
components are the remote thermostat and wiring
necessary to connect it.
The controls on the unit are not operational when
the remote control function is used.
Resistance Heat Models
The Zoneline 2800 resistance heat units may be
connected to a single-stage thermostat designed
for use with cooling and electric heat systems. GE
offers three thermostats compatible with the 2800
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.
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 2800 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.
Freeze Sentinel™ 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 operation.
RAK806 Universal Control Cover Label
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
directing the user to
the wall thermostat
for operation of the
Zoneline unit.
