Electrical connection
1.
Clamp the collector temperature sensor cable to the connector.
2.
Clip the connector onto the edge of the control system circuit board at position "TK" (2-pin, see Image 3-24).
3.
Route the collector temperature sensor cable through the labyrinth to prevent strain on the cable.
4.
Clip the mains and pump connection cables (premounted on the terminal block) to the edge of the control system circuit board
at positions "Power" and "P1/P2." The connectors are polarised to prevent errors.
5.
Place controller into the housing baseplate from above.
• Make sure that the loops in the cable are pointing downwards (as shown in Image 3-27 to Image 3-28).
