Undervoltage output
for alarm notification NO1(Phase)
N1(Neutral)
Undervoltage output 230V ac, 50Hz, 5A resistive, 1A inductive.
Should be connected to the relay coil in order to get a free contact.
(*) Alternatively, it is possible to use another output DO or OC , see paragraph 6.5.
7.9 SUMMER/WINTER OPERATION NOTIFICATION FUNCTION
It is possible to configure a digital output for the notification of the operating mode of the unit, plant side.
The digital output is active during summer operation, while is not active during heating operation or when the unit is OFF.
During the DHW production and the defrosting, the output maintains the setting of the former season.
For enabling this function, you should enter into the parameters as following: press

7.10 COMPRESSOR CRANCKASE HEATER
The crankcase heater operates when the compressor remains off for at least 30 minutes and if the discharge temperature is below
20°C (with hysteresis of 2.0°C). When the compressor restarts, the crankcase heater will stop.
7.11 ANTIFREEZE PROTECTION ELECTRIC HEATERS (IF THE KA ACCESSORY IS PRESENT)
The electric heaters of water antifreeze, installed on the outer surfaces of the evaporator plates, activates even when the unit is
switched off (but energized) if the outlet water temperature goes below
r02 °C (default is 4°C) in heating mode or below r03 °C
(default is 4°C) in cooling mode and in shut off condition. The same electric heaters are switched off when the temperature
measured by the outlet water sensor exceeds
r02+r06 in heating mode or r03+r06 in cooling mode and in shut off condition (the
default value is r06=2,0°C). The heating cable placed on the basement of the appliance turns on when the outdoor air temperature
decreases below 3°C and the unit starts the defrosting cycle (or if
r19 =0 even if the unit is not in defrosting cycle, or in stand-by
mode). It will be deactivated if the outdoor temperature exceeds 5°C or the last defrosting cycle is concluded after more than r19
minutes (default 10 minutes) (with
r19 ≠ 0).
In case you want to produce gelid water, it is necessary to modify the actions of antifreeze resistances, as well as the set of
activation of the antifreeze alarm (
A08 = 4°C by default) and its hysteresis ( A09 = 3.0°C by default).
7.12 ACTIVATION OF DOMESTIC HOT WATER PRODUCTION
To activate the DHW water production mode, be sure to install a temperature sensor inside the tank and to connect it to the AID2
– AID2 terminals (enabled as analog input). Once the temperature sensor is installed and connected, it is necessary to set the
domestic heat water function.
To enable this function you should get access to the parameters PRG
