Scale
Set the flow rate as follows:
Carry out setting whilst the circulation
pump is in operation.
1.
Open all valves in the heating and cooling
circuits 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.
You can read the set flow rate on the red
indicator ring in 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, you may restore the last value by turning
the stop ring until stop.
