## Questions & Answers

**Q: I have a nest hello, and i have had a problem with power. this product was suggested to me, but, what chime could i use?**
A: You should be able to use it with any chime that requires 24V power.

**Q: I have bought this transformer, it says it is 24v. i am reading 30v at the doorbell button. anybody know if it will cause a problem with a ring pro?**
A: 24 vac transformers normally put out 28 - 30 volts.  Any doorbell transformer that I have ever replaced is a 15 volt output transformer.

**Q: There are 2 points, labeled "R" and "C", on the transformer where you attach wires with screws. What do "R" and "C" stand for? "Remote" and "Chime"?**
A: “R” stands for “Red,” not rear. It is the hot terminal.  The hot wires in 24 volt AC systems are typically red. “C” stands for common.

**Q: Will this work with 16v chime**
A: I talked to Nutone, and they said their chimes take only 16V. This transformer may eventually blow out the chime. We got a NEST door bell, and it is rated for 16V-24V and 10-40VA. I got this b/c I want the higher voltage and higher watt requirements. If the chime burns out, so be it. A chime costs $20, I am not going to worry about it.
