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
20 gage solid thermostat wire.
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.
