M. HUMIDITY CONTROL
M.3 Humidity Control Settings
and Configuration
T
he Clear Control is designed to operate in
conjunction with the zone sensor discussed
earlier in the guide. These are the steps to verify
the zone sensor and adjust the humidity set-
point and operating modes. The system can be
programmed to a humidity level as low as 35%,
and can be set to run dehumidification as part
of the cooling cycle or as a stand alone system
regardless of the cooling or fan call status from
the thermostat, recommended.
NOTICE: The system will not operate the
humidity control when the outdoor ambient
temperature is below 60°F, this is because the
humidity control uses hot refrigerant bypassed
from the outdoor coil,. When the ambient
temperature is too low, insufficient heat will be
retained in the refrigerant to properly operate
the Reheat system for proper dehumidification.
The Reheat system in this packaged unit is not
designed for industrial or process applications,
it is intended for human comfort zones.
Navigate through the Clear Control menu to
“Humidity Control” it should say Enabled. If it
says “Disabled” press the Enter button twice to
Enable rh Control.
Next set the desired Relative Humidity Set-
point. This set-point will be where the control
will run the associated dehumidification cycles
to bring the humidity in the zone down to this
percentage.
Now set the Reheat Mode, there are three
functions to choose from, Reheat in Occupied,
will only run dehumidification when there is a
Fan or Cooling Call. Reheat in Unoccupied, will
on run dehumidification when there is no fan
or cooling call; Reheat ALL, (recommended)
will run reheat based on the humidity reading
regardless of the thermostat operation.
Checking the Humidity Sensor reading, Navigate
to Humidity Control then down to Indoor rh, this
will display the reading from the humidity zone
sensor. If this shows “4%” then it means that
the zone sensor is not connected properly or
malfunctioning.
Verify a 0-10VDC signal across the Field Cnfg 2
terminals on the control board. 10VDC = 100%,
5VDC - 50%.
The humidity control system is also equipped
with an Outdoor Fan Motor Controller, OFMC,
this controller changes the speed of the outdoor
fans to allow for more or less heat in the
bypassed refrigerant used to operate the reheat
system. Adjustments to the OFMC are not
needed unless undesirable operation occurs.
Consult the Installation instructions provided
with the system for details on the OFMC
operation and adjustments.
