The PAW solution for replacing solar pumps

and changeover to high-e

fficiency technology

Due to the requirements for the energy

efficiency of heating and solar pumps, only

high-e

fficiency pumps may be used in solar

thermal systems.

However, the controllers of older solar systems

are generally not compatible with the new

high-e

fficiency technology. High-efficiency

pumps always require constant mains voltage

for operation, the speed control is carried out

via separate/additional control signals (0-10 V

or PWM signal).

Older controllers are not equipped with an

appropriate control signal output.

In the case that an existing (asynchronous) pump has to be

exchanged without replacing the controller, PAW o

ffers the

PAW replacement set for solar pumps, consisting of:



High-efficiency pump



Pumps control signal converter (PSW)*



Connection cables



Sealing material

The table at the right helps you to find the suitable

replacement set for the solar installation.

*The PSW converts the controlled 230 V alternating voltage

such as control via pulse packages, phase angle or

trailing-edge phase into a PWM or 0-10 V control signal.
