3 (cascade) boilers, double direct circuits, 1 mixing circuit, 1 DHW tank circuit with solar collector connection
example (with plate heat exchanger between the primary and secondary circuits)
The examples above are informative figures for the reader to understand the possibility of designing a
variety of schemes. As a direct circuit, it could be taken as the domestic and conventional panel radiator
heating system and also floor heating or water to air heat pump ventilation. It is possible to derive different
variations.
Important:
Your aiM boiler are capable of being comissioned as a segmented cascade system up to 256 boilers. (16
segments x 16 boilers/segment = 256 boilers). It is also possible to centrally audit the whole system via the
OZW 672 web server (Section 4.2).
4. Comissioning and Adjustments
4.1.
Disassembling The Front Panel, Reaching The Front Control and
Electrical Wiring
4.1.1. Disassembling the front panel
Prerequisites:
None
Unscrew the front bottom (user side) screws. The front panel is hanged on the three pins on the front top
side of the boiler. The panel will be free to sweep around the top horizontal edge after unscrewing.
