SETTINGS – HEAT PUMP LOCKOUT
29
DEFINITION DEPENDENCIES FUNCTION
Pressing the HP Lockout
field in the “System Settings
Screen” will invoke the “HP
Lockout Screen” which will
allow a temperature choice
from OFF to 5°F to 55°F for
the aux heat lockout
functionality, adjustable in
5°F increments.
The HP Lockout functionality is
not available with the Outdoor
Equipment Type of NONE or AC
selected, because the aux heat
lockout functionality needs HP
heating to operate. This
functionality is also not available if
a valid outdoor temperature is not
available (resulting in a System
Event notification).
If a setting of OFF is selected, The heating equipment
cycle shall always start with the heat pump regardless
of the outdoor air temperature. If a lockout
temperature is selected and the outdoor air
temperature is less than the selected temperature, the
heating cycle is started with the AUX Heat source. If
the outdoor air temperature is equal to or greater than
the selected temperature, the heating cycle is started
with the heat pump. If the outdoor temperature is not
available, all heating cycles shall start with compressor
heat.
