ECL Comfort 310, application A376

7.3 Flow / power limit

Please see the explanation for flow and power limit in circuit 1.

At DHW heating the flow / power limit can be set to a fixed value.

OFF / 1 ... 50 s

OFF

Controls how fast the flow / power limitation adapts to the desired
limitation.

OFF:

The control function is not influenced by the ‘Adapt.
time’.

The desired temperature is adapted quickly..

50:

The desired temperature is adapted slowly..

If the ‘Adapt. time’ is too low, there is a risk of unstable control.
