DIG LEIT-1ASV-075 3/4 in. Solar Powered w/ Anti-Siphon Valve

LEIT Controllers are an advanced "ambient light powered" water management irrigation control system. Power is derived by a time-tested, internal photovoltaic module and microelectronic energy management system that is fueled by ambient light (solar). This provides power to the controller in any kind of weather, anywhere in the world.

Controller Features
  • No backup battery or AC power necessary - uses clean solar energy.
  • Simple, icon based intuitive programming.
  • Operates drip or sprinkler system.
  • Daily and monthly programming complies with city and municipal watering restrictions.
  • Manual On/Off button opens the valve and shows the time left to run.
  • Waterproof and humidity resistant
  • Power level meter indicates the approximate charge (energy available).
  • On activation, the controller display indicates when a program is running and when any programming feature is active.
  • User reset option allows erasing of all programs to default settings except time, day and date.
  • Program On/Off button: allows the user to turn off the controller/ valve and reactivate it as desired.
  • Available valves from 3/4 to 2 in.
  • Non-volatile memory.
  • Rain sensor connection
  • 3 year warranty
Programming Features
  • Five start times per day provides added flexibility for any type of watering application including sandy or clay soil.
  • Valve duration up to 5 hours and 59 minutes in one-minute increments.
  • 7 day programming schedule or 1-30 day intervals
  • 20 Preset Historical ET programs with 10 climate zones, 10 for drip irrigation and 10 spray systems.
  • Rain delay up to 99 days with auto restart.
  • Monthly seasonal adjustment budget ( 0 to 200%) in 5% increments without modifying the controller's program duration; also can be used to fine-tune the preset ET program for each month.

  • Anti-Siphon valve combines a remote control valve and backflow preventer in one unit.

Wouldn't charge
The unit I received wouldn't power on. I tried to let it charge in direct sunlight for hours and still got nothing. Since the defect policy is to repair/replace rather than refund, I ended up just going to a local hardware store to buy something else and losing out on the cost of this unit.

Installed and working for 4 months now
I bought one of these about 4 months ago and I have it installed programmed and running as promised. So far no issues, so much that today I am actually buying another one for another weird area that I don't want to run power to.

why will the timer not shut off after time is done?
alex r on Aug 19, 2018
BEST ANSWER: Probably because it has failed. I've owned about 17 of these things, and several have failed in this way. Have also had other problems like the covers blowing off in storms and lost gaskets because of frequent creature fouling of the open anti siphon valve (which I don't need). I like the basic idea, but the design can't be trusted. That said, DIG has been good about customer support. I suggest contacting them directly.
how to set the time of day ?
david c on Apr 17, 2019
BEST ANSWER: push big button in middle until time shows push arrows pointing right until time blinks push arrows pointing up or down to change numbers
I'm a homeowner looking to make a self sustaining greenhouse. Does this Solar Powered Drip system simply hook up to a water hose?
Anthony B on Jul 20, 2015
BEST ANSWER: No. The connections are NPT. You'd need to adapt to garden hose thread.
Do you also have solar timers for high impact sprinklers?

BEST ANSWER: I'm sure the timer with solenoid valve would work controlling an impact sprinkler if I understand your question. It can be programmed many different ways. I found it difficult to program but my son did it very easily.
Hope this helps
