Goodman PACKAGE TERMINAL AIR CONDITIONER/HEAT PUMP Installation Instructions & Owner's Manual page 13

Do not install the thermostat where it may be affected by the
following:
• Dead spots behind doors, in corners or under cabinets
• Hot or cold drafts from air ducts
• Radiant heat from the sun, appliances, or fireplaces
• Concealed pipes and chimneys
• Unheated (uncooled) areas behind the thermostat, such
as an outside walls
Consult the instruction sheet packaged with the thermostat for
further details on mounting and operation.
REMOTE THERMOSTAT OPERATlON
Approved thermostats vary slightly in construction and, with few
exceptions, are operated similarly. The following operational
description pertains to approved nonprogrammable thermostats
that energize G in Heat and Cool mode.
HEAT/OFF/COOL Switch
• OFF - cooling and heating functions are defeated.
• HEAT - the selected room temperature is maintained by
cycling either in the heat pump mode or electric strip
heat. A PTH unit is switched from the heat pump mode to
electric strip heat when the coil temperature is 20·F or
when the heat pump cannot keep up with the heating load
and a two stage thermostat is used.
• COOL - the selected room temperature is maintained by
cycling the air conditioner.
Table 4 summarizes the thermostat input combinations and the
respective unit functions. The following wiring schematic illus ­
trations show wiring schematics for heat pump and straight cool
units with electric resistance heat, respectively.

Table 4 - Remote Control Inputs
NOTE: The PTAC Wire Harness Kit (PWHK01 C) is required for
remote thermostat options.
ADDITIONAL NOTES:
1. For heat pump operation, a room thermostat with a B (heat­
ing change over) terminal or an 0 terminal (cooling change
over) is required. This wiLL mean that some "auto changeover"
thermostats cannot be used, as many of them either do not
have a B terminal, or else energize the B terminal continu ­
ously when in the "auto" position.
2. Additional wiring should be run for future changeover to Heat
Pump or thermostat options.
3. Run 6 to 8 wires during initial installation. Tape or cap off
any unused wires.
NOTE: Using a thermostat with an
0
terminal will require that
the 7 button with display control be configured (see Configura ­
tion Settings).
