2.2.1Power supply

Do not disconnect the controller from the mains supply!

The battery for saving all individualised data is otherwise unnecessarily strained. The frost-protection function of the controller is deactivated.

2.2.2Connection conditions

All electrical connection work may only be carried out by qualified personnel!

2.2.3Cable cross-sections

1.5mm2 for all cables carrying 230 V (power supply, burner, pumps, actuator).

0.6mm2 for bus cables (recommended type J-Y(St)Y 2 x 0.6).

0.5 mm2 for sensors, selectors and analog signal cables.

2.2.4Maximum cable lengths

Sensor, selector and analog inputs

We recommend using cables no longer than 200 m. Longer connection lines could be used, but increase the risk of interference.

Relay outputs Unlimited cable length.

Bus connections

Max. length of 100 m from the first bus subscriber to the last one (incl. wall modules).

2.2.5Cable installation

Install cables for sensors apart from the cables carrying 230 V! Branch boxes in the sensor cable must be avoided!
