Control Wiring

The control circuit is 24 volts AC (minimum 40VA) supplied from

the indoor unit.

tance between the indoor and outdoor unit.

2. Route one end of the control wiring through the opening

provided in the unit side panel and connect to the control

terminal strip using either Fig. 19 for 38HDF units and Fig.

20 for 38QRF units.
