WIRING DIAGRAMS
Figure 2: Wiring example (from top to bottom and left to right): 2 loads, 2 loads connected to different phases, shutter channel,
fancoil three-speed fan, fancoil three-point valves and fancoil open/close valves.
* 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, 150ºC].
INPUTS CONNECTION
Any combination of the following
accessories
is allowed in the inputs:
Zennio temperature
probe.
Up to two motion sensors
can be plugged into the
same device input (parallel
wiring)
Screw
terminal
for
connecting Zennio motion
sensors*.

⚠
In order to ensure the expected status of the
relays, please check that the device is
connected to the main power supply before
energizing the power circuit.
For a 4-pipe fancoil, the cooling valve should
always be connected on the left side and the
heating valve on the right side. Before the start-
up of the device, it must be assured that the valve
is completely closed.
Outputs that are not being used for valve control
can be used as individual outputs or shutter
channels.
Wiring the fancoil to the outputs of the lower side
of the device is similar to that of the upper outputs
(E1=A1, E2=A2, F1=B1, ...).
