Power Reduction Mode
Changing the Power Reduction program screen from OFF to
ON activates the power reduction control algorithm that
reduces total unit electric power consumption for 8 hours. The
use of the Power Reduction Mode should be established by the
shipper. When the Power Reduction Mode is ON:
•
The controller reduces the electric power consumption by
the percent selected: 10%, 20% or 30%.
NOTE: When the Power Reduction Mode is active,
the controller display will briefly show “PWRED ON”
every 10 seconds.
