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.
Adjust the Demand Reduction Climadry™ settings
using the up/down arrow buttons. Press the center
button to save changes.
• Suspend Climadry™ (default): While the
assigned Demand Reduction input is active,
Climadry™ is turned off, regardless of the
dehumidifi caiton demand.
• Allow Climadry: While the assigned Demand
Reduction input is active, Climadry™ will
operate normally.
NOTE: The thermostat must be confi gured for
humidity control by installer and the DXM2 must
