Low Voltage Wiring
■
Heat pumps—Connect 24V wires from the thermostat to the
corresponding wires in the control box using 18 AWG as
follows:
*Optional field installed heat connections
NOTES:
■
Thermostats must be set to energize “G” during cooling. This
is default on most all thermostats.
■
WGPH4549 and WGPH4560 have 2-stage cooling and
require 2-stage heat/cool with optional 3
rd
-stage electric heat
thermostat.
Internal Wiring
A diagram detailing the internal wiring of this unit is located on
the electrical box cover. If any of the original wire supplied with
the appliance must be replaced, the wire gauge and insulation
must be the same as the original wiring.
Transformer is wired for 230 volts on the 208/230 models. See
the wiring diagram for 208-volt wiring.
1.
Disconnect power.
2.
Remove the control access panel.
3.
Route the field supply wires through the line voltage conduit
opening to the electrical connection area, providing sufficient
length to connect to the pigtail leads.
Single Phase Units
■
Connect the field supply wires (L1, L2) to the 2 black pigtail
leads using UL-Listed wire connectors.
