Product description
The HeatBloC MC is a preassembled group of fittings for heating circuits. The integrated pump
can be isolated by means of ball valves and can thus be maintained without draining of the
system.
The nominal value for the differential pressure between the flow and the return is adjusted at the
controller. On this basis, the controller regulates the pump. Thus, the hydraulic balancing at the
distribution manifold is assured and an energy-saving operation of the pump is guaranteed at
any time.
The PAW HeatBloC must be either installed on a PAW modular distribution manifold or a PAW
wall bracket.
For the function of a MC system, one connection set (wall power supply, item no. 1398700) is
necessary. The connection set is not included in the scope of delivery.
