Setting supplementary electric heater setpoint
Index - String
MIN
value
MAX
value
Parameter function
0°C 65°C
This parameter indicates the deviation from the heating setpoint, for switching off the electric heater (if
active) in supplementary mode; as shown in Fig.12 on the previous page (Parameter Sri).
Setting electric heater band in supplementary/replacement mode
Index - String
MIN
value
MAX
value
Parameter function
0°C 20°C
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 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.
Setting outside air temperature threshold for supplementary mode
Index - String
MIN
value
MAX
value
Parameter function
-40°C 50°C
This parameter indicates the outside air temperature threshold, beneath which the heater is activated in
supplementary mode; as shown on the previous page, in Fig.11 Parameter tA1.
Setting outside air temperature threshold for replacement mode
Index - String
MIN
value
MAX
value
Parameter function
-40°C 50°C
This parameter indicates the outside air temperature threshold, beneath which the heater is activated in
replacement mode; as shown on the previous page, in [Fig.A] Parameter tA2.
Setting the band for air temperature
Index - String
MIN
value
MAX
value
Parameter function
0°C 20°C
This parameter indicates the band applied to the air temperature setpoints (tA1-tA2).
