33. Setting the flow limiter

The combi boiler is fitted with an adjustable flow

limiter (DHW draw-off rate).

The flow limiter is shipped with a flow rate set at the factory

to 8 l/min.

The flow rate can be changed via the green rotary selector

on the flow limiter.

The flow limiter can be adjusted between 5 and 13 l/min.

Procedure:

• Manually pull out the green rotary selector forwards.

• Increase flow rate Þ

rotate counter clockwise in

direction.

• Reduce flow rate Þ

rotate clockwise in

direction.

Check the selected flow rate on the display of the

AM display module or the BM-2 programming unit.

• Manually push in the green rotary selector to lock it.
