humidification signal (H terminal) to the humidifier
(off when the thermostat is in the COOL mode)
controls humidification. When the thermostat is
powered, the H terminal is normally inactive (open
circuit) in any mode (HEAT/COOL, HEAT, COOL,
OFF). When a humidification demand is present,
H terminal and G terminal are energized (24V).
The system must be in heat mode and had at least
one heating call before humidification feature is
active. Once humidification is active the
humidification modes are as follows:
Normal
: Runs humidification with a call for
heat and humidification.
Max
: Runs humidification with a
humidification call but without a call for
heating.
Dew Point Normal
: Runs humidification with
call for heat and humidification based on
outdoor temperature.
Dew Point Max
: Runs humidification with a
humidification call but without a call for
heating based on outdoor temperature.
A selection option under
Installer settings >
Humidity settings > Humidify
> Humidify mode
must be enabled before the user will have control
over the humidity. The humidity mode selected
determines how the user can adjust the relative
humidity (RH). The installer settings include
NORMAL
,
MAX
,
DEW POINT NORMAL
,
DEW
POINT MAX
, and
OFF
.
NORMAL & MAX
These thermostat modes allow the user to control
the relative humidity (RH) between 15 and 45%.
The following conditions must be met for either
mode to operate:
humidification mode has been enabled, and
the unit is in HEAT mode, and
humidification demand exists (24V present at
H)
Additionally, the
NORMAL
mode requires heat
demand exists (Y energized for heat pump
heating, or W energized for gas heat [W may be
energized with G de-energized]).
