Remote Thermostat Control
Heat Pump Models
The Zoneline 900 and 5800 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 2 thermostats compatible with the 900 and 5800
series units:
RAK148D1 — RAK148P1 —

connection wires. connection wires.
Please see page 57 for installation recommendations for the
remote thermostat wiring. Compatibility of other thermostats
considered for use with the GE Zoneline
of the customer.
The control voltage on the remote control conductors is 24 VAC.
The Class 2 Mode Switch, dip switch #4 on the auxiliary control
board on both the 900 series and the 5800 series, must be set
to the ON/UP mode to enable remote thermostat control. Refer
to installation instructions packaged with the chassis.
The fan speed for the 900 and 5800 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
following chart shows the unit operation when connected
to a remote thermostat.
Temperature Boost 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.
