Typical Wiring for Multiple PTAC Units Connected to a Single Wall Thermostat

NOTES:

1. Do not daisy chain R (24 VAC).

2. Maximum of 4 PTAC units can be connected to one single wall

thermostat.

3. Wall thermostat wire is field-supplied and should be 18 to

All units must be connected to same ground source.

To accomplish this, be sure to connect all units to

the same breaker box. Failure to do so may cause

damage to the unit.
