Note :
1.
Cable wire range : 28 ~12 AWG (0.2 ~ 0.8 mm²).
2.
Do not tun on the power before completing the wiring, cut off the power before changing the wiring.
3.
Pay attention to not reverse the EEV connection. EEV1 with the analog signal 1 and the EEV 1
parameters.
4.
Do not connect 24V- wire and GND wire together.
5.
If you want to use 1 analog signal to control 2 x EEV in parallel, please connect the 0-10V signal on both
analog inputs. Check that the 0-10V supplier voltage
doesn’t deform the signal.
