pump

The  differential  for  deactivation  of  the  heat 
pump. If the outdoor temperature exceeds Pa 
r14+Pa r13 the heat pump is turned back on. 

Pa  r15  Enable  integrated  electric  heater 
control

If  this  parameter  =1  the  electrical  heaters 
also act as integrated heaters.
If not (Pa r15=0), the electrical heaters only 
perform the anti-freeze function

Defrost parameters

Pa d01 Defrost enabled

0= defrost function disabled
1= defrost function enabled

Pa d02 Defrost start temperature/pressure

The  temperature/pressure  below  which  the 
defrost cycle is activated.

Pa d03 Defrost interval (response time)

The  period  of  time  during  which  the  probe 
remains below the defrost start temperature/
pressure. It is expressed in minutes.

Pa d04 Defrost end temperature/pressure

Temperature/pressure  above  which  defro-
sting starts.

Pa d05 Maximum defrost time (time out)

Maximum duration of defrosting. It is expres-
sed in minutes. 

Pa d06 Compressor-reversing valve wait time 
(anti-bleeding)

Wait  time  between  compressor  shut-down 
and reversal of the 4-way valve at the begin-
ning of the defrost cycle. 

Pa d07 Drainage time

Wait  time  between  compressor  shut-down 
and reversal of the 4-way valve at the end of 
the defrost cycle.

Pa d08 Temperature at which defrost starts if 
Pa H49= 1

Á  la  temperatura  al  di  sotto  la  quale  viene 
avviato il ciclo di sbrinamento. 

Pa d09 Temperature at which defrost ends if 
Pa H49= 1

Temperature above which the defrost cycle 
is ended.

Pa d10 Enable defrost compensation

Refer to temperature compensation at start 
of defrosting

Pa  d11  Defrost  temperature/pressure  com-
pensation offset

Refer to temperature compensation at start 
of defrosting

Pa  d12  Defrost  temperature/pressure  com-
pensation set point
