S The main power is supplied to both the indoor and outdoor

units.

S Consult local building codes, NEC (National Electric Code) or

CEC (Canadian Electric Code) for any special requirements.

S Use Table 7 for the electrical requirements for the outdoor units

and Table 8 for the indoor units to correctly size the cables and disconnect switches.

Control Wiring

Thermostat wires should be used for control wiring between the indoor and outdoor units. A two conductor cable is required for the cooling only units and a seven conductor cable is required on heat pumps. 18 AWG is recommended for any length up to 200 ft (61.0 m).

User Interface -- Finished Goods Accessory

Any of the following three thermostats can be used depending on the type of system on hand and the desired features. Refer to Table 9 to select the proper thermostat.
