In supplementary mode, the temperature of the water in the system is checked
before the unit is switched on. If the temperature is less than/equal to the value
calculated for the switch-on band, the electric heater will be switched on and will
operate as per the diagram on the previous page Fig.12. The value of the switch-on
20 °C band is calculated as follows: switch-on band = (Heating setpoint) - (Parameter Sri)
- (Parameter Bri); see Fig.12 on previous page;
In replacement mode, this parameter represents the band of deviation from the
heating setpoint, within which the heater will be activated or deactivated, as shown
on the previous page Fig.13.
This parameter indicates the outside air temperature threshold, beneath which
50 °C the heater is activated in supplementary mode; as shown on the previous page, in
Fig.11 Parameter tA1.
This parameter indicates the outside air temperature threshold, beneath which the
50 °C heater is activated in replacement mode; as shown on the previous page, in [Fig.A]
Parameter tA2.
Setting the band for air temperature
This parameter indicates the band applied to the air temperature setpoints (tA1-
20 °C
tA2).
