1. Which login do you mean? Login to your account on
www.bluespray.net or your controller login?
2. Yes, you can. By default, the controller runs in stack mode i.e. serially. In this mode, only one zone is on at a time, for a reason: residential homes may not have enough pressure to operate more than 1 zone. Operating more than 1 zone also requires more power. Our power supply can handle more 2-3 zones at a time, but if you have a master valve, that's another zone.
If you want to turn on more than 1 zone, select "No" for stack mode. For all practical purposes, we do not recommend this unless you really know what you're doing.
