SETTING ThE MINIMUM RPM FoR PUMP R9
A nominal system flow needs to be defined on behalf of installed collector surface. Nominal
system flow varies between 0.5 to 1.2 l/min for each square meter of installed collectors or
according to the manufacturer's recommendations (example: 3 solar collectors with total
surface of 6 m2 need to have nominal system flow of 5.4 l/min, if basic flow in system is 0.9
l/m for each square meter of installed collectors).
Next, manually activate circulation pump R9 on max. RPM - see chapter Manual mode on
page 29. Set pump speed switch to level where system flow is slightly higher as nominal
flow in system. Adjust the system flow with flow valve to match the nominal system flow.
Now, set (with the controller) the R9 RPM to 40 % and check on flow meter if there is flow
in system. If there is no flow in system, raise the R6 RPM to 55 %. If there is still no flow in
system, raise the R9 RPM to 70 % or raise the pump speed and repeat the whole procedu-
re again. If min. pump RPM was changed it needs to be set with parameter S6.11.
