CH Settings
CH Post Pump Time sets how long the central heating circulators will continue to operate at the completion of a heating call.
Any call during the CH Post Pump Time will be ignored until the post pump has completed. The CH Post Pump Time feature
allows the heat remaining in the appliance at the completion of a call to be sent to the heating system, which will improve the
overall efficiency of the system.
Touch the LEFT or RIGHT soft keys to adjust the CH Post Pump Time then touch the OK key to store the setting.
Default: 5 min
Circulation Pump Permanent allows the central heating circulators to be constantly enabled even without a central heating call.
A domestic hot water call will cause the circulators to be disabled during the domestic call as long as DHW Priority is enabled.
Touch the
UP or DOWN soft keys to select Enabled or Disabled then touch the OK key to store the setting.
• Enabled – The central heating circulators will be enabled for constant circulation without a central heating call.
• Disabled – The central heating circulators will only be enabled during a central heating call.

The Freeze Protection menu allows the feature to be enabled and disabled. The built-in frost protection mechanism activates the sys-
tem pumps as soon as the flow temperature [NTC1 probe] drops below 7°C. As soon as the flow temperature is at 5°C, the burner starts
up until the flow temperature rises above 15°C. The pumps continue to run for around 10 minutes.
Touch the
UP or DOWN soft keys to select Enabled or Disabled then touch the OK key to store the setting.
•
Enabled – The Frost Protection feature protects the installation from freezing at a predetermined system flow temperature.

Frost Protection Setpoint allows to define the outside air temperature at which the anti-freeze function is activated (only available if
