Hunter Sprinkler XC600i X-Core 6-Station Indoor Controller Timer 6 Zone,Black,Small

Q: What range of YEAR does this unit cover? I have an older Hunter which stops at year 2011 so I can't use it for automatic settings

pick any date off the current year. Then go backwards on the controller calander till that date appears on the same day and month. That year can be used in place of the current year. IN other words your birthday (day of week) will repeate it self every what seven years?

Q: have a hunter system the digital read out is blank ,changed the battery but no luck why

Hello, First, verify you have power at the outlet. Then use a meter to test the transformer output for 24 to 29 VAC. If you have the power and the transformer is good, then it's an internal issue with the timer and it will have to be replaced. Thank you

Q: can this unit be used as a indoor controller as well?

Yes, it can be used indoors, it has an external plug-in transformer. It can be used outdoors if it's protected from the elements, like in a carport or covering. For a true outdoor installation, you should look for the outdoor version that has a cabinet.
