Operating mode
/
0 - Only DHW (to control the ON/OFF switch
of the DHW function, use the ES and
GND contact in Figure 5-10);
1 - Cooling and Heating (to control the ON/
OFF switch of this two functions, use the
relative contact CS-GND and HS-GND of
Figure 5-10);
2 - All function are active. The “Tw” sensor
must be connected (to control the ON/
OFF switch of this functions, use the
relative contact of Figure 5-10);
3 - Only heating (Caution!!! In this mode
the contact HS-GND of Figure 5-10 is
disabled, so the function is continuously
active);
4 - Heating and DHW. The “Tw” sensor must
be connected (Caution!!! In this mode the
contacts HS-GND and ES-GND of Figure
5-10 are disabled, so the functions are
continuously active);

0A
Maximum duration for minimum compressor speed. When
the supply is higher than the setpoint value, the compressor
speed will be reduced. The compressor will be switched off
after having worked continuously at the minimum value for the
time set in this parameter. After the set time has elapsed, the
compressor restarts after 3 minutes.
