Installation Guide ECL Comfort 210 / 310, application A217 / A317
Example b:
A flow switch signal (S8) can be applied in order to heat the DHW
on demand (DHW tapping / DHW draw-off). An idle temperature
for the supply temperature (at S2) can be maintained to minimize
the heat-up time for the DHW.
Example c:
A flow switch signal (S8) can be applied in order to heat the DHW
on demand (DHW tapping / DHW draw-off). The temperature at
S3 is maintained during the comfort times of the circulation pump
P1. An idle temperature for the supply temperature (at S2) can be
maintained to minimize the heat-up time for the DHW.
Example d:
The DHW tank is directly heated. The setting of the return
temperature limitation (at S5) can avoid a too high flow in the
heating coil. An idle temperature for the supply temperature (at
S2) can be maintained to minimize the heat-up time for the DHW.
