The solar circulation pump on 230V-outputsA1 and

 

 

 

 

 

 

 

 

 

 

 

 

A2 can be operated either in switch-mode (two-point

 

 

 

 

 

 

 

 

 

 

 

 

controller) or in a rotational speed regulated way.

 

 

 

 

 

 

 

 

 

 

 

 

If the rotational speed regulation is activated the pump

 

 

 

 

 

 

 

 

 

 

 

 

power is adjusted by a controller so that switch-on
