Wiring diagram (also found on the cover of the control unit)<br />

The following wiring diagram provides an overview of the electrical installation.<br />

The diagram applies to both versions of the humidification system.<br />

The terminals X1 to X26 are located below the cover of the control unit<br />

(fastened with 3 screws). The terminals accept the following maximum<br />

cable cross sections: stranded wire 1.5 mm2 , solid copper wire 2.5 mm2 .<br />
