In order to properly connect two heat pump condensing units to a single 524A-H packaged air handler, it is necessary to add field-supplied Fan Coil Relay Board(s), P/N 33ZCRLYBRD. Relay board(s) no. 1 and no. 2 should be installed in the control box of condensing unit.

IMPORTANT: The common (COM) terminals from the fan coil relay board(s) must be connected to the ‘C’ terminal in condensing unit ‘A’.

Route thermostat cable or equivalent single leads of no. 18 AWG (American Wire Gage) colored wire from sub- base terminals through conduit in unit to low-voltage con- nections as shown on unit wiring diagram and Fig. 12 and 13.

NOTE: For wire runs up to 50 ft, use no. 18 AWG insulated wire (35 C minimum). For 51 to 75 ft, use no. 16 AWG insulated wire (35 C minimum). For over 75 ft, use no. 14 AWG insulated wire (35 C minimum). All wire larger than no. 18 AWG cannot be directly connected to the thermostat and will require a junc- tion box and a splice at the thermostat.
