* HEAT PUMP WIRING DIAGRAM NOTES:
• Note 1: For Heat Pump applications the jumper wire
must be connected between W1 and Y.
• Note 2: The “W2” terminal is used to call for Electric/
Auxiliary heat. If your Heat Pump PTAC does not have
Electric heat, then the “W2” terminal should not
be used and Installer Settings menu 10 (Aux. Stage
Oset) should be set to “OFF”.
• Note 3: For PTAC units with only one fan speed
(single “G” fan wire), add a jumper wire (installer
provided) to bridge together “GH” and “GL”. Connect
your fan wire to either terminal aer jumper wire has
been added.
** CONVENTIONAL WIRING DIAGRAM NOTES:
• Note 1: For Conventional (cooling) PTAC units, the
jumper wire between Y & W1 should be removed and
Installer Settings menu 06 (System Type) must be set
to “Con”.
• Note 2: If connecting to a Conventional PTAC unit
without electric heat, the W1 and W2 wire terminals
will not be used and Installer Settings menu 03
(Available Modes) should be set to “04: Cool Only”
• Note 3: For PTAC units with only one fan speed
(single “G” fan wire), add a jumper wire (installer
provided) to bridge together “GH” and “GL”. Connect
your fan wire to either terminal aer jumper wire has
been added.
