Key number: 8-85

- This value allows us to set speed of the double pump station in manual operation.

- Manufacturer setting is 0 % and must be changed to 100% (see paragraph

‘How to change the values’).

Settings with the password

- Once you set the values under key numbers: 8-62 and 8-85, press right button

which brings you to values where you have to insert the password number 25

- That will bring you to a second group of values which must be adjusted as

follows:

Please note: I will describe only those which must be changed and full description of

the key numbers you can nd in the instruction manual

Key number: 8-01

- A minimum difference between temperatures on the panels and the cylinder to switch the

double pump station ON

- A manufacturer pre-set value : 15 K (can be changed)

Key number: 8-02

- A minimum difference between temperatures on the panels and the cylinder to switch the

double pump station OFF

- A manufacturer pre-set value : 5 K (can be changed)

Key number: 8-30

- A solar nominal panel performance.

- A solar nominal panel performance is based for the calculation of the actual panel

performance together with the ow setting (8-37). Dependent of the actual panel

performance the digital controller can modulate pump speed and controller ow which will

increase performance and efciency of the solar system.

- A manufacturer pre-set value is 8 kW. You must change this value to 6 kW for every RM

Solar system.

Key number: 8-35

- Minimum pump speed in auto mode.

- A manufacturer pre-set value is 50%. You must change this value to 100% for every RM

Solar system.

Key number: 8-37

- This value allows us to set the ow on the solar system (no electronic ow meter

is needed).

- The ow is 1 L/min per collector. For two panel system the value is 2 L/min.

- If you install more than three panels this value must be changed.

3 panels – 3 L/min

4 panels – 4 L/min

5 panels – 5 L/min

And so on
