The PM2 is the all-round control solution, offering adjustable pump start from 1.5 to 5 bar. This enables customisation to different types of installation and desired comfort levels. The start pressure is set inside the unit, whereas current pressure is read on the intuitive LED display.
The PM2 starts the pump when the start pressure is reached, and keeps running as long as there is flow. It is equipped with an internal pressure tank to minimise starts and stops in the event of leakage in the installation.
In addition, the PM2 can be optimised for operation with a large external pressure tank by enabling the 1-bar differential pressure function. This significantly reduces the number of operating hours of the pump in installations with a pressure tank.
