If your heat pump has Energy Monitoring installed, the screen
shall be this:
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.)
Fan Operation
The thermostat can operate the fan in three ways:
AUTO (on only during heating and cooling calls)
CONTINUOUS (always on)
INTERMITTENT (cycles fan)
1. From the Home screen or Menu, press the Fan button.
2. Select the operation you desire as described above by
pressing the up and down arrows
▲▼
.
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.
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)
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.
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.
Display Dealer Information
The installing dealer’s contact information can be displayed on
this screen. From the main screen, press Menu and then press
Dealer. Simply press the screen segment where information is to
be entered and a keypad will appear.
