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

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.
