 Humiditrol: Runs based on humidity reading
from thermostat's internal humidity sensor,
heating set point and outside temperature.
Will over cool space based on settings of min
NOTE - The D terminal is ALWAYS activated
(24VAC) when the thermostat is in HEAT or OFF
mode; it is only inactive (0VAC - reverse logic)
during dehumidification.
Dehumidification adjustment will change the
relative humidity (RH) setting between 45 to 60%
RH (default setting is 50% RH). The lower the
number, the more humidity will be removed from
the air.
A selection option under Installer settings >
Humidity settings > Dehumidify > Dehumidify
mode must be enabled before the user will have
control over the humidity. The mode selected
determines how the user can adjust the relative
humidity (RH). The installer settings include:
1. NORMAL
2. MAX
3. AUXILIARY DEHUMIDIFIER
4. HUMIDITROL
5. OFF
NORMAL
In this mode, dehumidification occurs if these
conditions are met and signals are present at
specific terminals:
1. Dehumidification has been enabled on
installer settings.
2. Unit is in COOL mode.
3. Dehumidification demand exists (RH above
set point).
4. Cooling demand exists (Y1 energized).
MAX
In this mode, dehumidification occurs if all MAX
conditions are true, except cooling demand may
or may not be present. Maximum over cool from
cooling set point is 2ºF.
