[2-78]= Heat pump lockout temp
Heat pump would be locked out when the outdoor ambient
temp is smaller than the Heat Pump Lockout Temp below –
this setting is only affective when heat pump lockout mode
has been set. Unit will switch to heat pump lock out.

Heat pump would be resumed when the outdoor ambient
temp is recovered by differential (below) above the Heat
Pump Lockout Temp.

When HP lockout mode has been set the auto backup func-
tion will automatically be set. This will allow the auxiliary or
secondary heat source to be automatically energized in the
event of a system failure.
Error codes capable of auto backup are listed in the table below.
Please be aware that the error codes that are not listed do
not auto backup in order to protect the unit.
