4.3.1
Fire‐up / Damping
Once this function has been selected, the fire‐up process starts.
The user is asked to confirm the fire‐up process activation.
The next stages of fire‐up process are described in section:

Temperature settings
 After selecting a given icon, the display shows a panel enabling the user to change the setting using a
slider or arrows.
Pre‐set CH temperature
This option is used to define the pre‐set temperature of the CH boiler. The setting range available is 55°C‐80°C
(the setting range may be changed by the manufacturer or fitter in the service menu).
Pre‐set DHW temperature
This function is used to define the pre‐set temperature of the domestic water. After the water in the tank
reaches this temperature, DHW pump is disabled. The pump will be enabled again when the temperature
drops below the pre‐set temperature minus the value of DHW hysteresis (read from the DHW sensor). DHW
temperature range: 40°C‐60°C.
