AC Infinity Cloudline Wiring Cover with Zen54 and PWM Module

---Updated---
Replacement Motor Cover for the AC Infinity Cloudline series fans.
This cover has mounting tabs on the inside that allows for the attachment of a 
Zooz z-wave zen54 0-10v dimmer module to control the motor speed through home automation.  

Important:
Do not use the AC Infinity supplied controller. It must be disconnected/removed.

2026-06-02:
Added a new model that allows you to add a 0-10v to PWM module.  This also requires a 
transistor, 2 resistors and 4 m2-4 hex cap screws. PWM Module is fastened to cover using a qty of 4 M2-4 Hex cap screws.  You could also fasten using hot glue.

The old model can still be used if you prefer to not use the PWM module.  

Please refer to the Schematic image or PDF for wiring information.

Problem with only using the Zen54, you loose the lower speeds that the fan is capable of.
The AC Infinity fan uses a “10v” DC PWM signal.  The PWM Module that I used has a “5v” DC output.  Adding the transistor and resistors allows you to use almost the full “10v” supplied from the AC Infinity fan. This addition allows the fan to run at a minimum speed of “2” on the Zen54.

Important to also adjust the potentiometer on the PWM Module to obtain maximum output.
Rotate the potentiometer clockwise until you hear a clicking sound. If your boards potentiometer does not click I would suggest measuring the voltage across the 
“Yellow (pwm)” and the “Black (gnd)” and rotate the potentiometer until you reach macimum voltage.  I suggest setting the Zen54 to “50” when performing this. At “50”, you should see around “5v”.

Transistor:

Resistors (¼ watt):
1K    Resistor
10K Resistor

Optional:
While not needed, I highly recommend using ferrules on the ends of the wires.

Create a simple “module” with the transistor and 2 resistors along with some wire and shrink tubing.

make sure to slip shrink tubing on all connections before soldering
All wiring should be 4 to 6 inches, 24 AWG is fine.  When assembling, trim to fit.

Connect a 1K resistor to the collector of the transistor
Connect a 10K resistor to the base of the transistor
Connect the open end of the 2 resistors together.
Attach a red wire approx 4 to 6 inches in length to the point that the 2 resistors meet
Attach a green wire to the transistors emitter
Attach a yellow wire to the junction of the 1K resistor and the collector of the transistor.
