AL 35 Anti-freeze alarm delay in HP for low outlet air temperature (air/air)
Attention
If during the Stand-by or remote off there is an anti-freeze alarm event, and
the AL35 <>0, starting the heat pump mode, from keyboard or digital input. In
this case the anti-freeze alarm is aborted and the compressor starts for the
AL35 time to heat the air or the water.
After the AL35 time if the antifreeze probe value is still lower than AL33
setpoint, for maximum AL36 seconds, the unit is stopped and the anti-freeze
alarm is generated again.
