3.3 Operating elements and
display
The flow rate is displayed, set, measured and
regulated with the help of the flow measuring
and regulating devices.

Abb. 3: Construction flow measuring and
regulating device
(1) Cylinder for setting
(2) Stop ring
(3) Scale
Set the flow rate as follows:
Carry out setting whilst the circulation
pump is in operation.
1. Open all valves in the surface heating/
cooling circuit completely.
2. Set the required flow rate by turning the
cylinder.
Clockwise = Reduction of the flow rate /
close completely.
Anticlockwise = Increase of the flow rate /
open completely.
The set flow rate can be read off
at the red indicator ring inside the
sight glass. The scale shows values
between 0 and 5 l/min.
3. Carry out setting of all heating/cooling
circuits.
4. Check the set values and readjust if
required.

The last set value can be restored with the help
of the stop ring.
1. Remove the cylinder for setting.
2. Turn the stop ring downwards until stop.
3. Refit the cylinder for setting to the flow
measuring and regulating device.
After a temporary modification of the flow rate,
the last value is restored by turning the stop
ring until stop.
