Setting the safety threshold
MAX value
Temperature threshold above the Force-Off, which reactivates the start-up of the compressor after the switching off
20 °C
for Force-Off.
Setting integral time
MAX value
The units possess an advanced logic for controlling the processed water temperature; the complete check prevents
999 s the system arriving at a point of equilibrium at a higher or lower temperature 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 derivation time
MAX value
Time within which the input water temperature is checked to estimate the load on the system; if the band on the
120 s
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 temperature the
20 °C 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;
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.
Setting the supplementary electric heater or activating the boiler
MAX value
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 domestic 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.
Panel control configuration
MAX value
This setting configures the type of control applicable to the units; depending on the value decided for this setting, the
controls on the functioning mode (HEAT/COOL) and the unit on/off command will be managed in the following way:
Set value 0:
- Setting functioning mode = set parameter 0
- ON/OFF control = from the panel on the machine
Set value 1:
- Setting functioning mode = set parameter 0
3
- ON/OFF control = from the remote panel
Set value 2:
- Setting functioning mode = set from remote contact
- ON/OFF control = from the panel on the machine
Set value 3:
- Setting functioning mode = set from remote contact
- ON/OFF control = from the panel on the machine
