IS there an easy way to add an extra zone?

    Hi All,
    I have a Nelson controller that is currently maxed out at 9 zones. I need 1 more zone and wondering if there is an easy way to get it to work with my existing equipment or if I need to spring for a new controller. Any ideas?

    Switch to Rainbird. That way when you need to add zones you just slip in another module.

    They do make battery controlled electric valves. You could add one of those in and not have to worry about the controller. I installed a hunter model the other day...it has up to 9 different start times daily!

    How much money do you want to spend?

    How far are you going to have to run wire to the existing controller? Any walks or hardscaping to go under?

    Another alternative might be a Doubler or SwitchHitter. But get ahold on the wallet 'cause they ain't cheap!

    I forgot about those. We use them a lot. But again...they are not cheap.

    Add a Nelson 8010 Actuator and a Nelson 7901 valve and you will be set to go. The actuator is battery operated [they work great] and runs on a 9-volt battery. Saves time and mess of running extra wire for an extra zone.

    Doubler costs: $110.00
    12 zone timer average cost: $150-200

    Preparing for future upgrades at time of installation : Priceless

    Seriously though, new timer......ProC Rainbird ESP Hardie Raindial...cannot go wrong with any of these.

    Thanks for all the tips. It won't be too tough to wire a new controller so I'll probably go that route. The new controllers have so many more features I think that alone makes it worth the upgrade.
    Thanks again.

    Wait a minute Tony. YOU recommended the RB ESP! I thought you hated that timer. Just giving you a hard time.

    Yes go the route of a new timer. Rainbird ESP modular should cost you $65-$80 for the first 4 zones. 2 modules at $20 a piece, $40. That gives you 10 zones at about $120. Maybe more depending on your discount. And it is capable of adding another modular to expand at later time.
