If your heat pump has Energy Monitoring installed, the screen
shall be this:
If the FAN hasn’t been on for an hour, the fan will start cycling
based on these times. Default is OFF. The first screen is the
amount of time you want the fan to be energized. Ranges are
OFF to 20 minutes in 5 minute increments. Then adjust the
time of the fan is OFF. Ranges are 5-40 minutes in 5 minute
increments. Fan ON and OFF cycles will continue until the fan
has been energized by a call for heating or cooling.
Humidity
(NOTE: This option is not available if configured as a Zone
Thermostat, but is available at the MasterStat)
NOTE: The humidity function must be enabled by the installer
for it to display on this screen. If your system does not use a
humidifier this function may not be enabled.
(If configured as a Zone Thermostat, the menu will appear as depicted
below.)
The humidity function must be enabled by the installer for this
screen to be visible. If your system does not use a humidifier
then this option may not be enabled. This allows adjustment of
Humidification and Dehumidification settings. Options are Auto,
Manual, factory default setting for Dehumidification is “Auto”.
Humidification “Auto” is only available if an outdoor sensor
is installed. Humidification only works with an active heating
call. Manual humidity choices range from 15% to 50% in 1%
increments. Dehumidification choices range from 35% to 65%
in 1% increments.
Fan Operation
Active dehumidification
(Variable Speed Heat Pumps Only)
This feature will only activate during cooling operation and is based
upon the humidity set point of the thermostat being at least 5%
below the actual relative humidity. When in active dehumidification
the room temperature could be overcooled 1.5°F below set point.
In this mode you may see increased energy usage due to the
additional compressor run time.
The thermostat can operate the fan in three ways:
AUTO (on only during heating and cooling calls)
CONTINUOUS (always on)
INTERMITTENT (cycles fan)

Intermittent Fan
Temperature conditions can vary widely between the thermostat
location and extremities of the space the thermostat serves.
This air stratification problem can be especially pronounced
during mild outdoor conditions when long periods elapse
between space conditioning demands from the thermostat. This
intermittent fan operation can also improve the performance of
air cleaning or special filtration systems that locate the cleaning
or filtration media at the return air side of the fan.

Press NEXT button. It will bring you to the installer setting page three.
Smart recovery is a feature of your thermostat designed to
improve comfort by adjusting temperatures to achieve a room
temperature by the programmed time. When it’s time for a
programmed temperature change, smart recovery begins
working in advance, turning the system on and off as needed to
adjust the indoor temperature. During these transition periods,
you may notice that the actual temperature and your temperature
setting don’t match. That’s smart recovery in action, adjusting
temperatures in small increments for greater energy efficiency.
This is more energy efficient than simply allowing the system to
operate at full capacity until the desired temperature has been
met. Smart Recovery helps avoid excessive use of auxiliary heat
when recovering from night setback in the heating mode.
Set Anticipator
(NOTE: This option is not available if configured as a Zone
Thermostat)
This adjustment controls the sensitivity and cycle rate of the
thermostat. Higher numbers decrease the cycle rate. Lower
numbers increase the cycle rate. Default value is 1, and the
range is 0-9.
Electric Heat (Aux) Lockout
(NOTE: This option is not available if configured as a Zone
Thermostat, but is available at the MasterStat.)
When an outdoor temperature sensor is installed, you can set it
up so the electric heat or Dual Fuel option doesn’t energize if the
outdoor temperature is above a certain temperature. Ranges for
this are NONE (default) to 40˚F in 5˚ increments.
Accessories
(NOTE: This option is not available if configured as a Zone
Thermostat, but is available at the MasterStat.)
Cooling Lockout
(NOTE: This option is not available if configured as a Zone
Thermostat)
When an outdoor temperature sensor is installed, it can be set
up so cooling option doesn’t energize if the outdoor temperature
is below a certain temperature. Ranges for this are NONE
(default), 45˚F, 50˚F, or 55˚F.
Each of these options has settings for Cumulative Run Time
and Calendar Time. Messages will flash at the top of the Main
screen when these events are met to alert the owner that it is
time to service these options.
Air Filter - Cumulative Run Time default is 1000 hours and
Calendar Time is 3 months. Values can range from
NONE-2500 hours for Cumulative Run Time (in 100

screen, the seven days usage will be displayed across the top,
and the current day and daily average will be displayed along
the bottom. In the monthly screen, the 12 months usage will
be displayed across the top, and the current month, monthly
average, and annual total will be displayed across the bottom.
These are just images representing energy usage, not actual
data from the system. You can view both the weekly and
monthly data. After approximately 5 minutes of inactivity, the
demo mode will exit and go back to the home screen.
Auto Changeover
With auto changeover, the thermostat automatically switches
itself from heating to cooling, or vise versa, based on the
setpoints. When setting up the thermostat you have to enter
both a cooling setpoint and a heating setpoint. The thermostat
will also prevent the user from setting the cooling setpoint lower
than the heating setpoint. Mode is set to AUTO for this operation
to work.
