ECL Comfort 310, application A376
Domestic Hot Water (DHW, circuit 3):
If the measured DHW temperature (S4) is lower than the desired
DHW temperature, the motorized control valve (M1) is opened
gradually and vice versa.
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 desired DHW temperature cannot be reached, the heating
circuits can be closed gradually to allow more energy to the DHW
circuit.
An anti-bacteria function is available for activation on selected
days of the week.
A 376.1, A376.2 and A376.3:
The return tempeature (S6) can be limited to a fixed value.
A376.2, DHW circuit, extra functions:
The DHW circuit can operate with or without DHW circulation. The
DHW temperature at S4 is maintained at ‘Comfort’ level when a
DHW tapping is ongoing (the flow switch (S8) is activated).
In order to compensate for the reaction time, the motorized control
valve can be pre-activated at the start of a DHW tapping.
An idle temperature can be maintained at either S6 or S4 when
there is no DHW tapping.
