Page 6: Product Description
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. -
Page 7: Function
The mixing valve is adjusted by an external controller (HeatBloC MC42 and MC44) or an internal controller (HeatBloC MC43) in combination with the electrical actuator. *bypass for MC43 and MC44 only Application range: Installations with several HeatBloC®s and different flow temperatures (radiators and radiant... -
Page 8: 3-Way Mixing Valve [Specialist]
Product description 3.3 3-way mixing valve [specialist] The 3-way mixing valve (C), driven by an electric actuator, adjusts the flow temperature of the consumer circuit to the required value by means of the flow sensor and the controller. The mixing valve is equipped with a bypass which must be operated separately. Via this bypass, cold return water can be added to the flow. - Page 9 Product description 1. During commissioning, determine the optimum bypass position for the operation of the installation. Find out and check the correct adjustment through a trial-and-error process. If the slot of the bypass screw is in a vertical position, the bypass is closed. If the slot of the bypass screw is in a horizontal position, the bypass is completely open.

Maintenance [specialist] 6 Maintenance [specialist] 6.1 Disassembly of the strainer out of the differential pressure sensor (DPS) NOTICE A maintenance of the differential pressure sensor may be necessary in different time intervals. The duration of the time interval depends on the quality of the heating water. A maintenance is necessary no later when the measurements of the differential pressure sensor vary strongly and a stable regulation of the pump is no longer possible. - Page 26 Maintenance [specialist] 5. Dismount the differential pressure sensor by removing the flat plug from the clip. The flat plug is equipped with a clamp spring. Press the clamp spring in before removing the flat plug. 6. Finally remove the clip laterally out of the fitting. 7.
