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 pre-
vious 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).
