7.6.5 Configuration 10.3
Picture 23. Configuration 10.1
Work principle:
If the temperature in the boiler is higher than Th19 and if the difference between temperatures of two
probes is higher than Th57, the system heats the water in the buffer. P3 Pump is on if the temperature in
the buffer has reached Th59.
Anti-freeze and over temperature protection has been described above.
Example and recommended values:
Th18
=5°C,
Th19
=40°C,
Th21
=70°C,
Th57
=5°C,
Th59
=50°C.
