Table 7 — 50PC Electrical Data with Constant Torque ECM Blower Motor
LEGEND
LOW VOLTAGE — For heat pumps with PSC (Permanent
Split Capacitor) or constant torque ECM (electronically com-
mutated motor) fan motors, all thermostat wiring is connected
to a terminal block located in the unit electrical box. Refer to
the unit wiring diagram for connection details.
Unless provided with WSHP Open, the WSHP can be con-
trolled using the included thermostat inputs (R, O, Y1, C, G)
for single stage heat pump thermostat or field-installed DDC
(Direct Digital Controls) controls. Note that the reversing valve
on the unit is energized when the unit is in the cooling mode.
See Fig. 19 for typical thermostat connections.
Fig. 19 — Typical Thermostat Connections
Thermostats should be located on an interior wall away
from supply ducts. Avoid locations subject to direct sunlight or
drafts, or external walls. Thermostat wiring should be 18 AWG
(American Wire Gage). Refer to the installation instructions for
the thermostat for further details.
