which requires the system’s blower fan to run during a call for
dehumidification.
• Cooling: this uses the air conditioning components in a flexible
manner to try and achieve the target RH% set point without separate
dehumidification equipment. This option provides a setting on the
next screen which permits intentional “over-cooling” beyond the cool
mode set temperature, if the dehumidification RH% setpoint has not
been reached. This setting allows up to 15F degrees of over-cooling.
Dehumidification RH% setpoint range is from 40% to 80%
HUMID:
This is for controlling an in-duct humidifier, either powered with its own
separate power source or the existing system’s 24 VAC transformer (see
wiring options below).
Humidification RH% setpoint range is from 10% to 60%.
AUTO-HUMID:
This is for controlling the same equipment as HUMID (above), however
the RH% setpoint is not directly adjustable by the user. The RH%
setpoint is automatically adjusted and controlled with a sliding scale
based upon present outdoor temperature.
