ATTENTION ! Correct flow rate depends on the sort of collectors, type of collectors and overall dimensions. 

Set the recommended minimum flow rate to 0.3 l/min for 1 m

2

 of active area of the collector (example: 2 collectors with active area of 2.0 m

2

 each – minimum flow rate is: 2 

 2 = 4 

 

0.3 = 1.2 l/min. 
Set the nominal (maximum) flow rate to 1 l/min for 1 m

2

 of active area of the collector (example: 2 collectors with active area of 2.0 m

2

 each – nominal flow rate is: 2 

 2 = 4 

 1.0 = 

4.0 l/min. 

The controller enables cooperation with a mechanical rotameter or

 an

 electronic flow meter of the G-916 type or any other electronic flow meter.   

Select the main flow meter connected to 

FLOW1

 terminals.

 

The second flow meter connected to 

FLOW2

 terminals is by default set as 

Electronic G-916.

 

Measurement: Electr.G916 

– cooperation

 with an electronic G-916 flow meter. 

The controller reads the number of impulses and converts it into the real flow (liters per minute). 

 

 

Nominal 

 

flow rate

 – entry to the nominal flow rate option results in switching P collector pumps on with maximum efficiency. Enter the calculated flow rate value that 

results from the number of collectors in the system into the edition field. Next, set the required flow in such a way that the “

Current” 

value corresponds to the calculated 

value entered before. The required flow can be obtained by changing the rotational speed in option 

Collector Pump.
