Operating Guide ECL Comfort 310, application P318
By means of a week schedule, the DHW circulation can be ON /
OFF controlled.
The motorized control valve M1 is opened gradually when
the charging temperature is lower than the desired charging
temperature and vice versa.
Alternatively, the control pump P1 / V1 is increased in speed when
the charging temperature is lower than the desired charging
temperature and vice versa.
The return temperature S5 can be limited, for example not to be
too high. If so, the desired charging temperature at S3 can be
adjusted (typically to a lower value); this results in a gradual closing
of the motorized control valve or, alternatively, a lower speed of
the control pump.
The ON-OFF output X1 is ON at DHW heating demand.
As an option, the desired DHW temperature can be set externally.
A voltage signal (1 - 10 Volt) can be applied to input S12 (ECA 32 /
35). The scale for voltage versus temperature can be set.
An anti-bacteria function for the DHW buffer is available for
activation on selected days of the week.
The anti-bacteria function can be set to include the DHW
circulation.
