Domestic Hot Water (DHW, circuit 3):
By means of a week schedule (up to 3 Comfort periods / day), the
DHW circuit can be in 'Comfort' or 'Saving' mode (two different
temperature values for desired DHW temperature).
If the measured DHW temperature (S6) is lower than the desired
DHW temperature, the heating circulation pump (P1) can be
switched OFF and the DHW heating pump (P2) is switched ON. The
motorized control valve (M1) is controlled in order to maintain the
DHW heating temperature at S3.
The DHW heating temperature is typically 10-15 degrees higher
than the desired DHW temperature.
DHW tank with 1 temperature sensor:
When the measured DHW temperature (S6) gets higher than the
desired DHW temperature, the DHW heating pump (P2) is switched
OFF. A post-run time can be set. The motorized control valve (M1)
will hereafter maintain the desired flow temperature in the heating
circuit.
DHW tank with 2 temperature sensors:
When the measured DHW temperature (S6) gets higher than the
desired DHW temperature and the lower temperature (at S8) gets
higher than the cut-out temperature, the DHW heating pump (P2)
is switched OFF. A post-run time can be set. The motorized control
valve (M1) will hereafter maintain the desired flow temperature in
the heating circuit.
