Controls manual
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
VRefer to temperature compensation at start
of defrosting
Pa d13 Defrost temperature/pressure com-
pensation delta
Refer to temperature compensation at start
of defrosting
TP t03 Cooling circuit high pressure
To express the pressure value in bar divide
the read valued by 100.
TP t04 External temperature
External temperature display
