## Questions & Answers

**Q: Would I have to reset the settings after an electrical power failure? & what are the default low and high pressure settings?**
A: The controller does NOT lose the setting after power failure. The recommended pressure settings for the regular household are 30 psi low and 50 psi high.

**Q: Does this work with pressure tank, or directly in line ?**
A: Works for botk, but to fill the tank you need a little backpressure for the pump protection not to kick in

**Q: I want to use this in a recirculating hot water system for pump shutoff if the system is drained. Set on at 20, off at 75 psi. Will this work?**
A: It should work fine

**Q: I cant seem to adjust the low and high set points when there is pressure on it.  Anyone else have this problem?**
A: One more thing, what pressure you try to adjust, I use it for well water amd I only need 27 to 52 psi, with liquid (water), if you go higher or maybe compressed air might be different.
