Safety instructions
2 Safety instructions
The installation and commissioning as well as the connection of electrical components require
technical knowledge commensurate with a recognised vocational qualification as a fitter for
plumbing, heating and air conditioning technology, or a profession requiring a comparable level
of knowledge [specialist].
The following must be observed during installation and commissioning:
• relevant local and national regulations
• accident prevention regulations of the professional association
• instructions and safety instructions of this manual
The HeatBloC must only be used in heating circuits filled with heating water
according to VDI 2035 / Ö-Norm H 5195-1.

Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant
properties get lost. We do not assume liability nor provide warranty for damage to property
resulting from sealants damaged in this way.
It is imperative to avoid that EPDM gets in contact with substances containing mineral
oils.
Use a lubricant based on silicone or polyalkylene and free from mineral oils, such as

Product description
3 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 and an energy-saving operation of
the pump is guaranteed at any time.

Product description
3.1.2 Function
The boiler charging set prevents the temperature in
the boiler from falling under the dew point, thus
reducing the contamination of the boiler.
The return temperature to the heat generator is kept at
the set temperature level by the integrated mixing
valve. Hot water from the boiler and cold return water
are mixed to reach the desired return temperature to
the heat generator.
• return flow temperature maintenance for
solid fuel boilers, wood firing and stove heating
systems
• for a constant flow rate in the heat generator

3.3 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.
3.3.1 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)

3.4 Check valve
The HeatBloC is equipped with a check valve (B-1) in the flow pipe and with a non-return valve
(C-1) in the mixing valve. The valves can be opened.
During operation, the marking must be directed to "Z".
The check valve is closed.
Flow only in the direction of the arrow.
For filling, draining and venting the installation, the marking
must be directed to "A".
The check valve is open.
Flow in both directions.
