COMPONENTS & INSTALLATION
REMOTE THERMOSTAT
Z
oneline® Vertical units
 are 
controlled by a wall-mounted 
thermostat. GE Appliances offers 
a complete line of thermostats to 
interface with the units, or most 
24-VAC thermostats may be used. 
Low-voltage wiring connections are made to the 8-pin 
harness included with each unit. This harness allows 
for a single-point thermostat connection to simplify 
chassis removal and reinstallation. See diagram below 
for terminal designations.
If a non–GE Appliances thermostat is used, the 
compatibility of the thermostat with the unit is the 
responsibility of the installer. The unit has an integral 
transformer, and no external voltage or transformer 
may be used.
Maximum wiring length and wire size: AWG 18 up to 
66 feet; AWG 20 up to 66 feet; AWG 24 up to 40 feet.
 ENERGY MANAGEMENT
GE Appliances also offers the
 RAK180W1 universal thermostat 
 that provides occupancy-sensing
 energy management. 
The thermostat works on single-stage or two-stage 
heating systems and operates on a DC or AC signal.
The energy management setup can work on a room-by-
room basis or it can be upgraded with a network controller 
for full site management.
Power to the thermostat can be via batteries or a 
two-wire connection from the Zoneline Vertical 
chassis. Command control signals are all conducted 
via wireless communication.
For proper wireless communication, the transmitter 
control card must be located on top of the Zoneline 
Vertical chassis and NOT inside the metal cover.
DUCTWORK & SUPPLY REGISTERS— 
FIELD SUPPLIED
Ductwork and supply registers are mentioned here as 
System Essential Components, because they are necessary 
to complete the installation. These components are field 
supplied per the HVAC engineer’s design.
ELECTRICAL INFORMATION—GENERAL
Zoneline Single Packaged Vertical air conditioners are to be 
connected to a single-phase 60 hertz power source. Units 
with the voltage designator “D" in the 8th character of the 
model number may be operated on either nominal 230-
volt or 208-volt power. Units with the voltage designator 
“E" in the 8th character of the model number are to be 
operated on nominal 265-volt power (A.K.A. 277-volt 
power). For all installations, feeder, sub-feeder, branch 
circuit and electrical protective devices must conform to 
all local codes. In the absence of a local code, the National 
Electrical Code should be followed.
Each unit should be installed on a single branch circuit. 
More than one unit per branch circuit is not recommended. 
All wiring must conform to local electrical regulations and 
codes. When in doubt, consult the National Electrical Code.
