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
Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.

Product description
3 Product description
The HeatBloC 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.

3.3 Pump [specialist]
The pump can be completely isolated. It can be replaced and maintained without draining the
HeatBloC. Close the ball valves (A-2, C-1) above and beneath the pump.
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)
