The system pump is switched on demand .
Exceptions:
- The system pump is switched off for domestic hot water
heating with priority control despite a possible heat demand
for room heating.
- The system pump is switched on when there is a risk of
freezing, even if no heat is required for room heating.
- When the system is shut down for a long period, the
system pump is switched on for approx. five seconds
every 24 hours to prevent the pump from seizing up.
