13. Economizer controls are set to a standard factory setting.
Nevertheless, you can adjust these settings through the filter
access door. Review the settings in the Operation section:
(1.) The standard economizer controller has a factory
setting of “C” for the outdoor air temperature
changeover and 63_F (17_C) for the supply air
(mixed air) temperature sensor. The outdoor air
temperature changeover setting is adjusted on the
sensor by setting the dip switches on the sensor.
The ABCD potentiometer on the economizer
control should be set to the “D” position.
(2.) The low ambient compressor lockout switch setting
is fixed at 42_F (5.6_C).
(3.) The minimum position for the outdoor air damper
can be configured at the controller. When not using
a CO
2 sensor, the DCV Max potentiometer must be
completely closed (CCS) for the Minimum Posi-
tion potentiometer to function correctly.
(4.) Settings for the optional outdoor enthalpy sensor,
indoor enthalpy sensor, and CO
2
sensor can also be
configured at the controller.
14. Replace the filter access panel. Screw in place ensuring all
seams are air and watertight.
15. Install all economizer accessories then power HVAC unit
and test cycle economizer.
