I have a very similar problem to Wyze Thermostat making clicking noise.
I ran a new wire to my Taco HVAC control board with R, W and C wire, such that the C wire is connected to “common”. I’ve verified that the voltage between R and C is 28VAC and W to C is 0. However, the wyze thermostat is just not booting up and is just clicking.
Is the issue overvoltage? Under supply? Does anyone know what my multimeter should be reading at various points?
Thanks in advance
