Setting heating FORCE-OFF

MAX
value
The heat pumps check the working temperature (input or output), to which a safety threshold is con-
70 °C nected, and beyond which the compressor is switched off immediately and automatically; this threshold
is called FORCE-OFF.

Setting the safety threshold

MAX
value
Temperature threshold above the force-off, which reactivates the start-up of the compressor after the
20 °C
switching off for force-off.

Setting integral time

MAX
value
The units possess an advanced logic for controlling the processed water temperature; the complete
check prevents the system arriving at a point of equilibrium at a higher or lower temperature compared
999 s
with the one set in the work setting. Remember that an increase in the integration time weakens the
effect of the integral control.

Setting derivation time

MAX
value
Time within which the input water temperature is checked to estimate the load on the system; if the
120 s
band on the setting value is exceeded within this time, the unit will be activated.

Setting the anti-freeze threshold

MAX
value
In the units it is possible to set a threshold for the anti-freeze alarm; this value specifies at what tempe-
20 °C
rature the anti-freeze alarm is activated. Remember that, to modify the anti-freeze threshold parameter,
the corresponding dip-switch must be activated (see the dip-switch configuration table).

Setting frost protection

MAX
value
In the units, it is possible to set a safety control on the water output temperature; on the basis of the
value assigned to this parameter, the anti-freeze electric heater is managed as follows:
• value 0, anti-freeze electric heater absent;
• value 1, anti-freeze electric heater installed and working only with machine in heat or cool mode;
0 4
• value 2, anti-freeze electric heater installed and working also in standby, but switching on the pump;
• value 3, anti-freeze 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
monitor the temperature of the water throughout the system.
