2. Function (in principle)
PM-controllers provide a residential unit with domestic hot water without the need
for external energy. The domestic water is heated according to the continuous flow
principle by a plate heat exchanger and the pressure controlled proportional flow controller.
Meibes PM-controllers have an anti-scale coating and DVGW (German Association for Gas
and Water) approval.
Operation
The PM controller only opens the domestic water and heating water media flows via the plate
heat exchanger when the hot water is being drawn off. Once the water has been drawn off, the
valve closes and thus prevents the continued heating of the heat exchanger.
