Anti-Short Cycle Timer (ASCT)
A protective short cycle timer is factory installed and located
in the control panel of the outdoor section. If power to the
compressor low voltage control circuit is interrupted, the
outdoor unit will not energize for approximately 5 minutes.
High Pressure Switch (HPS)
A high-pressure switch is factory-installed and located in
the liquid line internal to the outdoor unit. The switch is
designed to protect the system when very high pressures
occur during abnormal conditions. Under normal
conditions, the switch is closed. If the liquid pressure
rises above 650 psig, then the switch will open and de-
energize the outdoor unit. The switch will close again
once the liquid pressure decreases to 460 psig. Please
note that the switch interrupts the thermostat inputs to the
unit. Thus, when the switch opens and then closes, there
will be a 5 minute short cycling delay before the outdoor
unit will energize.

Low Pressure Switch (LPS)
A low-pressure switch is factory-installed and located in
the suction line internal to the outdoor unit. The switch
is designed to protect the compressor from a loss of
charge. Under normal conditions, the switch is closed. If
the suction pressure falls below 5 psig, then the switch
will open and de-energize the outdoor unit. The switch will
close again once the suction pressure increases above 20
psig. Please note that the switch interrupts the thermostat
inputs to the unit. Thus, when the switch opens and then
closes, there will be a 5 minute short cycling delay before
the outdoor unit will energize.
