7.4 Programming the Control
I
If your AC has a Shaded-Pole (SP) fan motor
instead of a Split-Capacitor (SC) High-Velocity
(HV) fan motor, you must change the parameter
P-14 setting to shaded-pole (SP) before operating
the equipment. SP units are recognizable by an
overhanging blower motor. Only reprogram the
fan motor type parameter if you do not have an HV
blower.
I
For CW Only: Standard air handlers come
equipped with chilled-water bypass valves.
However, for no-valve air handlers, the fan must be
set to cycle on demand (CYC).
I
For DX Only: If your air conditioning unit is cool-
only (if it does not have a reversing valve), you
must change the parameter P-33 setting from heat
pump (HP) to cool only (CL). Refer to “Selecting a
Parameter” on page 16.
– You must change the parameter before setting the
Automatic mode for a cool-only unit.
