1.
Utility Load Shedding Mode ACTIVATED (Utility
Cycled Unit OFF)
– The normally closed set of
contacts in the utility load control receiver
open
. This
interrupts the 24VAC signal from the
Y1 Out
terminal
on the outdoor control to the compressor contactor coil
and the compressor will be cycled
OFF
. The outdoor
fan will continue to operate during a thermostat
demand. The 7‐segment display on the outdoor
control will
NOT
display an alert code and the iComfort
WiFi
®
thermostat will
NOT
display an alert. The
customer will not be notified by email when the load
shedding mode is activated by the utility company.
Note
Some utilities may require the entire outdoor
unit to cycle off during utility load shedding. If the entire
outdoor unit is required to cycle off, the "preferred
wiring method" shown in figure 27 must be used.

Utility Load Shedding Mode DEACTIVATED
(Normal Equipment Operation)
– When load
shedding is not required, the contacts in the utility load
control receiver are closed. The circuit is completed
between the

terminal on the outdoor control to
the compressor contactor coil. The outdoor unit will
return to normal operation.
