Compressor
Configuration
Power limitation value:
The compressor frequency is limited to this percentage of the maximum allowed frequency when
the
Frequency Reduction Mode (P068)
parameter [FREQ_RED] is set to “Yes” (LOADFACT). It
can be activated with the power limitation switch. (%)

Fluid type
:
Sets the fluid type in the heating circuit:
1 = Water; fluid type is always set to “water”

External main pump control:
This parameter is taken into consideration only when Factory Par. 804 is set to “0”, i.e. internal
pump is NOT available.
If there is no internal pump on the unit, then the external pump control can be enabled
.
561
No / Yes
No
27
Flow checked if pump OFF: Allows the water flow rate to be checked if the water pump is OFF
562
No / Yes
Yes
28
Anti seize function :
Pump anti seize function:
The pump is started and run for 30 seconds provided that the pump has been inactive for 24
hours
0 = anti seize function disabled
1 =anti seize function enabled

Pump sampling time standby:
Pump sampling time (Stdby):
If no user interface or local user interface and P565=2 then the water pump will cycle, depending
on the value of P564 in order to obtain a correct refreshed water control measurement (minute)
Must be used with P565=2 to enable this control

Main pump logic:
This parameter is used to define the state of the pump in Standby mode:
1 = Always On
2 = Water Sampling (RC local, On/Off according to P564)
3 = According to Space Temp (RC remote as Thermostat)
565
1 ~ 3

31
Variable speed pump logic:
Allows the variable speed pump logic to be set depending on installation requirements:
0 = Adjustable speed (use “vsp_max” to set the fixed speed)
1 = Speed controlled by the Water Delta T

Additional pump logic:
This parameter defines the status of the additional pump when the unit is in Standby:
0 = No additional Pump (no add. Pump logic active)
1 = Always On
2 = According to Space Temp (RC remote)
3 = Always On, but Off when DHW is active
4 = According to Space Temp (RC), but Off when DHW is active
