Setting the anti-freeze threshold
In the units it is possible to set a threshold for the anti-freeze alarm; this value spec-
ifies at what temperature the anti-freeze alarm is activated. Remember that, to
20 °C
modify the anti-freeze threshold parameter, the corresponding dip-switch must be
activated (see the dip-switch configuration table).
Setting Frost protection
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;
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.
This parameter indicates which logic must be used to manage the supplementary
electric heater; the choice of logic is determined by the value set in this parameter
so, depending on the value, the settings are:
0 = no supplementary electric heater present on the unit;
1 = supplementary electric heater present, but cannot be activated during hot do-
mestic water production;
4 2 = electric heater activation command used as consent for activation of an external
boiler;
3 = supplementary electric heater present and active during hot domestic water
production;
4 = electric heater activation command used as consent for activation of an external
boiler which can also be used in supplementary mode;
WARNING: to set the value at (4), the DHW accessory is needed.
