1.2 Wired Wall Thermostat Connection Kit

The PTAC Wire Harness kit provides connection from termi-
nal strip on the PTAC control board to the following board
features:
• Front Desk Control
• Remote Fan (relay must be manufacturer-approved and
have a AC low voltage coil)
• Remote Thermostat (confirm with manufacturer approved).
* If other than a "dry switch" is used in connecting these fea-
tures, consult manufacturer before proceeding.
The PTAC Wire Harness kit contains the following:
1. 7-pin connector for a thermostat connection
• C - Cormmon
• R - 24VAC
• Y - Compressor
• W - E/Heater
• O - Reversing Valve (only on PTHP)
• GH - High Speed Fan
• GL - Low Speed Fan
Note: If there is only one Fan connection(G), connect to
either GH or GL depending on desired fan speed.
Do not wire the thermostat to energize heat pump
and heat strips simultaneously as this will result in
a wiring error.
