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.
