• Off Time: options: 5 to 90 minutes (in 5 minute
increments)
NOTE: This intermittent fan operation can also
improve the performance of air cleaning or special
fi ltration systems that locate the cleaning or fi ltration
media at the return air side of the fan.
5.6.7 SERVICE INFORMATION (System Status and
Fault Information)
These additional screens help the service personnel
to have a better understanding of what problems
might be occurring before arriving for service.
5.6.7.1 FAULT STATUS
Fault Status mode displays the active fault code as
well as the fi ve most recent stored fault codes that
occurred on the system.
Navigate between system fault codes using the up/
down arrow buttons. Press the center button to
view more information about potential reasons why
the highlighted fault may have occurred.
5.6.7.2 TEMPERATURE STATUS
Temperature Status mode allows the user to view
the status of all temperature sensor readings
including onboard and remote sensors.
NOTE: If a temperature sensor is not connected
or a temperature reading is out of the valid range,
N/A will be displayed.
5.6.7.3 CLEAR FAULT HISTORY
Clear Fault History will clear all fault codes stored
in the thermostat.
5.6.7.4 SYSTEM STATUS
System Status mode allows the user to view the
status of all temperature sensor readings as well
as the operational status of the blower and pump.
NOTE 1: If any temperature reading is out of the
valid range, N/A will be displayed.
NOTE 2: If the connected communicating control
is not confi gured for Pump by installer or no
valid pump information is communicated by the
connected control, N/A will be displayed.
5.6.8 SETPOINT LIMITS
Use this option to limit the heating and cooling
setpoints. This function is used to avoid setting
the cooling temperature too low or the heating
temperature too high.
Adjust the maximum heating and minimum cooling
Setpoint Limits settings using the up/down arrow
buttons. Navigate between Setpoint Limits using the
left/right arrow buttons. Press the center button to
save changes.
• Maximum Heating (default 95°F): valid range:
60 to 95°F (in 1°F increments)
• Minimum Cooling (default 55°F): valid range:
55 to 80°F (in 1°F increments)
NOTE: The thermostat will operate with a fi xed
Minimum Heating Setpoint value of 55°F and a
Maximum Cooling Setpoint value of 95°F.
5.6.9 DEMAND REDUCTION - External Sensor Input
Demand Reduction is used to reduce the electric
load while peak utility rates are high. While the
Demand Reduction mode is active, the thermostat
will implement load reduction by limiting operation or
capacity. The thermostat outputs will be limited by
the Demand Reduction option selected below (section
5.6.9.1).
NOTE: The thermostat must be confi gured for
Demand Reduction by installer to access Demand
Reduction settings.
5.6.9.1 DEMAND REDUCTION MODE
Through Demand Reduction Mode, you can set the
unit's limited operation while Demand Reduction is
active.
Adjust the Demand Reduction Mode settings using
the up/down arrow buttons. Press the center
button to save changes.
• No Auxiliary Heat (default): While the
assigned Demand Reduction input is active,
auxiliary heat will not be activated regardless of
the heating demand.
• No 2nd Stage Compressor: While the
assigned Demand Reduction input is active,
the compressor is limited to only part load (1st
stage) operation and auxiliary heat is turned off
regardless of system demand.
• No Operation (default – if either setting is
not present): While the assigned Demand
Reduction input is active, the thermostat
outputs will not be activated for heating or
cooling regardless of the heating or cooling
demand.
NOTE 1: The thermostat must be confi gured for
auxiliary heat by installer to access the Demand
Reduction NO AUXILIARY HEAT option.
NOTE 2: The thermostat must be confi gured
for Multistage by installer to access the Demand
Reduction NO 2nd STAGE COMP option.
5.6.9.2 Climadry™ - DEMAND REDUCTION
This option allows for the customization of
Climadry™ (Dehumidifi cation, optional) operation
while Demand Reduction is active.
