Setting of the flow rate:
Setting is carried out whilst the circulation pump is in operation.
1. Open all valves in the surface heating/cooling circuit completely.
2. Remove the red cap by pulling it upward (1).
3. Loosen the black collar nut by turning it anticlockwise (2).

key (3)
clockwise = flow rate is reduced
anticlockwise = flow rate is increased
The set value can be read off at the red indicator ring inside the
sight glass.
The scale shows values between 0 and 5 l/min.
5. Carry out setting of all surface heating/cooling circuits.
