system is installed.
The automatic filling function ensures that the
operating pressure is maintained. If the operating
pressure drops below the set value, the filling valve
opens until the set pressure is reached.
To protect against e.g. leakage, the filling valve
closes in the following cases:
• No pressure increase can be measured.
• The set filling time is exceeded.
Small: < 8 radiators
Medium: 8 – 15 radiators
Large: > 15 radiators
Only available if the max. number of fills has been
reached. Before use, ensure there is no water
escaping from the heating system.
