can be integrated also in existing heating systems parallel with solid fuel boiler (exemplary diagrams are shown on Fig. 1 and 2 page 10). It is recommended for safer operation the electric boilers to be mounted in systems operating with a pump securing enforced circulation of the heat medium. - Page 5 The mainboard is joined by the individual elements shown in respective power wires arrangement. When replacing the boiler sensor or mainboard, but not replace the sensor, it is possible to obtain the temperature difference. For this purpose it is necessary to adjust the reading by trimmer potentiometer P2.

economical in terms of protection of the electrical installation. (Ideal option for heating one premise). 5. OPERATION MANUAL - The customer has to provide water supply and electricity to the installation. - The customer monitors for leaks and controls the operating pressure in the system. - Adjust the boiler or room temperature depending on the operating principle of the installation and personal preferences. - Page 9 1. Boiler should be mounted at a place suitable for servicing (free access thereto) and possibility of opening the front lid. 2. Boiler should be mounted suspended on the wall at minimum height of 1 m off the floor. 3.
