modulate to maintain the suction pressure
setpoint. If the space temperature deviates
below the space cooling setpoint minus ½ of
the space temperature deadband the reheat
relay is activated.
The dehumidification priority determines
whether or not Dehumidification Mode
takes priority over Heating and Cooling
Modes. Default is False. If set to True,
Dehumidification Mode will enable any
time the space humidity rises above the
dehumidification setpoints, regardless of the
current mode at that time. If set to False,
Dehumidification Mode will enable only
when the space heating and cooling
setpoints are satisfied (i.e. vent mode if FAN
OCC = ON) and the space humidity has
risen above the dehumidification setpoints.
See WattMaster MHGRV Controller manual
for modulating hot gas reheat operation.
Equipment with Modulating Hot Gas Reheat
will require an additional supply air
temperature sensor be field installed for the
modulating reheat controls.
CO
2
Economizer Override
As the CO
2
ppm increases above the CO
2
setpoint the economizer outside air damper
position increases proportionally to increase
ventilation to the space. As the CO
2
ppm
decreases toward the CO
2
setpoint the
economizer outside air damper decreases
proportionally toward the minimum outside
air damper position. Compressor lockout
and economizer supply air low limit have
priority over CO
2
override and CO
2
override
has priority over the economizer control.
Note:
CO
2
Override requires a field installed
CO
2
sensor.
Remote Averaging Space Temperature
Option is used to average the space
temperature with the controller’s internal
space temperature sensor and a remote space
temperature sensor for space temperature
control.
Remote Space Temperature
Option is used to disable the controller’s
space temperature sensor and only use a
remote space temperature sensor for space
temperature control.
Fan Status
Option is used to confirm the operation of
the supply fans. An alarm will be activated
if fan operation cannot be confirmed
Note: Because of the AAON Mini
Controller’s limited number of inputs,
only one of the following options is
available
with
a
single
controller:
Dehumidification,
Enthalpy Controlled
Economizer,
CO

Override,
Remote
Averaging Space Temperature, Remote
