High power readings

[Katm995]

 

my power readings for my nest thermostat seem very high. I do not have a c wire installed. I have Y-G-R-W. The picture is when the unit is on. Similar readings when it is off. I also hear a clicking noise when I am close to the thermostat and it’s running. Is this normal or should I be concerned?

Hello @Katm995,

Thanks for reaching out. Here are the ideal power range if there isn't a C wire in your thermostat, according to Google:-

• Voc: 29 to 42V

• Vin: 29 to 42V when your system is not running (6 to 7V when your system is running)

• Iin: 20 to 40 mA

It looks normal for the voltage readings.

Hope that helps! 🙂

Mine is over 30 V when it is running. Doesn’t seem like the normal range you listed

Hello @Katm995,

Is it possible for you to provide an image on your wiring to further help you diagnose?

Thank you.
