WIRING DIAGRAMS
Figure 2: Wiring example (from left to right): three-speed fan, load and open/close valve, load
and open/close valve to different phases.
* In case of using ZN1IO-DETEC-P sensor, its micro switch number 2 must be in
Type B position
.
** Zennio temperature probe or any NTC with known resistance values at three points in the range [-55, 150 ºC].
