Hi all,
I've been enjoying a Heatermeter 4.2 on a Zero Pi W since last fall. I'm now trying to add a RD3 to the mix (hard-wired - no RDTC board), but I'm having some trouble. My forum searching has not yet turned up the 'dummies guide' I clearly need...
The issue is that I get no response from the fan (Delta BFB0512VHD) nor the servo (Towerpro MG90S). I've tried setting the temp setpoint at 225 and -100 - in both cases the fan did not turn on at all. The grill/ambient temp was around 67, so I would expect a 225 setpoint to push the blower into afterburner mode.
RD3 RJ45 jack has been wired per https://github.com/CapnBry/HeaterMeter/wiki/Blower-and-Servo-Wiring:
I should mention that I'm powering the HM 4.2 through the Pi Zero W - no 12v brick here. Is that power adapter required to support a blower/servo?
Thanks,
Marino

RD3 RJ45 jack has been wired per https://github.com/CapnBry/HeaterMeter/wiki/Blower-and-Servo-Wiring:
- The servo has 3 wires: red (punched to RJ45 pin 3), orange (punched to RJ45 pin 6), and brown (capped off)
- The fan also has 3 wires: black (punched to RJ45 pin 4), red (punched to RJ45 pin 5), and blue (capped off)
