the fi rst, second, and third stage differential values combined
(User Manual section 5.6.2.3), below the setpoint.
8.0 Demand Reduction
Confi guration
Demand Reduction is activated by an input signal at the unit
control board to reduce the electric load while peak utility
rates are high. The Demand Reduction Confi guration mode
selects which of the available unit control inputs is to be
used as the activation signal. While a physical input signal is
present at the selected input, the thermostat will implement
load reduction by limiting operation or capacity. Refer to
section 5.6.9 in the User Manual for more details on Demand
Reduction.
Adjust the Demand Reduction Confi guration setting using
the up/down arrow buttons. Press the center button to save
changes.
