All HVAC components can be tested to confirm the
signals between thermostat and unit are being
sent and were received.
NOTES: After 5 minutes without a test being
initiated, the test modes is disabled and system
goes back to the normal mode (i.e. HOME
screen).
When in SYSTEM TEST MODE, the compressor
minimum off timer is bypassed.
Humidify
OB
o
Humidification (adding moisture to air) is provided
only when the thermostat is in heat mode. The
37
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]).

DEW POINT NORMAL & MAX
Dew point adjustment mode will change the
humidification set point based on the outdoor
temperature and a user-defined dew point
adjustment setting.
NOTE - In dew point adjustment mode, the
humidification set point has no effect whatsoever
on unit operation. Only the user-defined dew point
adjustment setting affects operation per the
following the above formula.
Dehumidify
Dehumidification(removing moisture from air) can
occur only when the thermostat is in cool mode.
When a dehumidification demand is present, a
dehumidification signal (0VAC - open circuit) is
present at the D terminal. This is used to reduce
the speed of the indoor blower during
dehumidification. At the same time, the Y1 and Y2
(if available) terminals become activated with
24VAC. The H terminal is inactive (0VAC - open
circuit) during dehumidification.
System must be in cool mode and had one call for
AC before feature is active. Once dehumidification
is active the dehumidification modes are as
follows:
Normal: Runs dehumidification with a call for
cooling and dehumidification.
Max: Runs dehumidification with a
dehumidification call but without a call for
cooling.
Auxiliary Dehumidifier: Runs based on
humidity reading from thermostat's internal
humidity sensor and will call for
dehumidification using the auxiliary
dehumidifier (whole house dehumidifier).
39
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.
40
AUXILIARY DEHUMIDIFIER
The auxiliary dehumidifier setting is used when a
whole home dehumidifier is used for
dehumidification. This requires:
1. Whole home dehumidifier has been wired to
thermostat per dehumidifier installation
instructions.
2. Dehumidification has been enabled on
installer settings.
3. Unit is in COOL mode, (or if in AUTO, there
has been at least one thermostat cooling call
made prior to the dehumidification demand).
4. Dehumidification demand exists (RH above
set point).
HUMIDITROL®
If Humiditrol is enabled in the installer settings,
then this adjustment affects overcooling
operation. Overcooling ranges from 2ºF below the
cooling setpoint (MIN setting) down to 2ºF above
the heating setpoint (MAX setting). Halfway
between the two settings is the MID setting.
If a Humiditrol® EDA is installed and enabled, then
the thermostat must be configured to properly
operate the Humiditrol® EDA as follows (see
Figure 22 for the Humiditrol® EDA operation
flowchart):
Check the HUMIDITY SETTINGS in user settings
to confirm that the user has turned ON
dehumidification setting.
NOTE - Humiditrol® EDA operation requires use
of an outdoor sensor. If sensor is not connected
and Humiditrol® EDA is enabled, “OUTDOOR
SENSOR REQUIRED” is displayed in the
information display.
Cooling only—Dehumidification will only occur if:
1. Dehumidification demand is present.
2. Cooling demand is not present.
3. Outdoor temperature is less than 95ºF,
4. Indoor temperature is not cooler than 65ºF or
cooler than the heating set point + 2ºF (IF the
difference between cooling and heating set
points is greater than the deadband).
In this case, 24VAC is removed from the D
terminal and Y1 and Y2 terminal (if available)
becomes activated with 24VAC. This cycles the
41
indoor variable speed motor to the
dehumidification speed and cycle Y2 ON to the
outdoor unit. Cooling has priority over Humiditrol®
calls. Humiditrol® mode is allowed to over cool up
to 2ºF above the heating set point.
Heat only—Thermostat will cycle heating ON and
OFF to maintain heating set point.
Dehumidification functions are disabled.
Heat/Cool—Dehumidification will only occur if a
dehumidification demand is present, a cooling
demand is not present, outdoor temperature is
less than 95ºF, indoor temperature is above 65ºF
and the indoor temperature is not cooler than 2ºF
above heating set point.
Note: If the last thermostat demand was a heating
demand, the thermostat does not require a cooling
demand before Humiditrol® operation.
Dew point adjust is only available when an outdoor
sensor is attached.
Other Humiditrol® EDA Notes
If the outdoor sensor is disconnected while
HUMIDITROL is enabled, the thermostat will not
allow operation in dehumidification mode.
Set point range: 45 to 60% Relative Humidity
(RH). Factory default - 50%.
Relative Humidity controls to within 2% on either
side of RH set point.
When the “D” terminal is activated with 24VAC,
dehumidification is inactive.
NORMAL, MAX and HUMIDITROL modes are
disabled by default from the factory.
As a precaution, regardless of how low the heating
set point has been set, Humiditrol®
dehumidification is inhibited below 65ºF indoor
temperature.
Unit Part (Catalog) & Serial Numbers
Humidity Sensor Fault
If the humidification sensor fault occurs, then the H
terminal becomes inactive, and the D terminal
goes to 24VAC.

User Settings
Memory Protection
The thermostat stores all the information
concerning its programming (state, mode,
program information, last temperature measured)
in a nonvolatile memory.
Please refer to the user guide for information on
the following:
Performance reports
Editing schedules
This function avoids the loss of the state of the
thermostat when a power-down occurs. The only
thing that might be lost is the clock and date
information, however, a super capacitor will
remember clock / date information for as long as it
has a charge (approximately 24 hours). When
power down occurs (due to a power outage) the
thermostat is able to shut off heat relays (Y1, Y2,
W1, W2) when in heating mode and W1 and W2
when in cooling mode. The O and B relay will
maintain their last state. When power is restored
the thermostat will be in heat /cool mode so either
mode can run to re-satisfy the temperature setting
Under the user settings menu, the following items
