3-way mixing valve [specialist]
The 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.
Position 10: Passage,
no mixing, return temperature
consumer = return
temperature boiler
Position 0:
100% mixing
flow temperature heat
generator = return temperature

Pump [specialist]
Isolation of the pump
The pump can be completely isolated. It can be replaced and maintained without draining the
HeatBloC.
1.
Close the ball valves in the flow and the return (A-2, F-2).
2.
Remove the actuator from the mixing valve.
3.
Turn the rotary knob of the mixing valve such that the black nose is directed to "VL zu"
(flow closed). The mixing valve is now closed and drop tight.

Pump settings
The pump has been correctly adjusted at the factory. In the case of a breakdown of the control
(no PWM signal), the pump runs at maximum rotation speed. To assure a proper functioning of
the heating circuit, the pump must be set as follows:
•
PWM profile (heating)
