Setting Heating limit flow temperature

Index - String

MIN

value

MAX

value

Parameter function

30°C 70°C

The heat pumps monitor this set temperature (input or output), beyond which the com-

pressor is switched off immediately and automatically; this threshold is called FORCE-OFF.

Setting the Reset hysterisis following limit

Index - String

MIN

value

MAX

value

Parameter function

0.5°C 20°C

In heating, this is the temperature threshold below the force-off, which reactivates the

start-up of the compressor after the switching off for force-off.

Setting integral time

Parameter function

secon-

The units possess an advanced logic for controlling the processed water temperature;

the logic prevents the system arriving at a point of equilibrium at a higher or lower tem-

perature compared with the one set in the work setting. Remember that an increase in

the integration time weakens the effect of the integral control.

Setting derivative time

Index - String

MIN

value

MAX

value

Parameter function

secon-

Time within which the input water temperature is checked to estimate the load on the

system; if the band on the setting value is exceeded within this time, the unit will be acti-

vated.

Setting the freeze protection alarm temperature

Index - String

MIN

value

MAX

value

Parameter function

-50°C 20°C

In the units it is possible to set a threshold for the freeze protection alarm; this value spe-

cifies at what temperature the freeze protection alarm is activated. Remember that, to

modify the freeze protection parameter, the corresponding dip-switch must be activated

(see the dip-switch configuration table).

Setting frost protection mode

Index - String

MIN

value

MAX

value

Parameter function

In the units, it is possible to set a safety control on the water output temperature; on the basis of the value assi-

gned to this parameter, the anti-freeze electric heater is managed as follows:

• value 0, freeze protection electric heater absent;

• value 1, freeze protection electric heater installed and working only with machine in heat or cool mode;

• value 2, freeze protection electric heater installed and working also in standby, but switching on the pump;

• value 3, freeze protection electric heater working in standby without the pump being activated;

• value 4, with external air temperature less than 3°C, the pump is activated for 2 minutes every 30, to moni-

tor the temperature of the water throughout the system.
