Installation and connections Solar circuit pump Installation The "SolarĆDivicon" pump station includes the circulation pump with connecting cable. Alternative pumps must be type-tested and fitted in accordance with manufacturer's instructions. Connection (without connection extension) 3Ćcore cable with cross-section of 0.75Ămm2.

Installation and connections Sensors Collector temperature sensor Installation Connection Collector installation instructions To S1 (terminals 1 and 2). Extension: 2Ćcore cable with cross-section of 1.5Ămm2. Cylinder temperature sensor The cylinder temperature is recorded indirectly through measuring the return temperature of the heat transfer medium inside the indirect coil. This results in enabling a reloading of the DHW cylinder through solar energy, even if only a little DHW is drawn off.
Installation and connections Mains electrical connection Regulations Carry out the mains connection and all earthing measures (e.g. fault current circuit) in accordance with IECĂ364, the requirements of your local electricity supplier, VDE regulations or all local and national regulations. The power supply to the control unit should be protected by a fuse with a max. rating of 16ĂA. Make the mains power supply connection (230ĂV~) via a mains isolator (two-pole) to be provided on site.
