Introduction
Thank you for purchasing DIG’s LEIT-2 controller, which operates as part of the
LEIT-2 system. This manual describes how to get the LEIT-2 controller up and
running quickly. After reading this manual and having been familiarized with
the basic functionality of the controller, the manual can be used as a reference
for less common tasks in the future.

About the LEIT-2 System
The LEIT-2 ambient light (solar) powered irrigation controller is an advanced
wireless device that is programmed using the LEIT RC2 remote handset. The
LEIT-2 controller is comprised of a photovoltaic module (PVM panel), 2 pairs of
18” (45 cm) station wires (labeled #V1 and #V2) used to connect the controller
with up to two S-305DC solenoids, plus a pair of yellow wires for sensor
connection. The LEIT-2 has an ultra-compact photovoltaic module that
harnesses light energy to generate electricity that is stored and used to power
the controller day and night in any kind of weather. The LEIT-2 controller is
operated using the LEIT RC2 remote control handset, which has an operating
range via a 2-way radio of up to 350 ft (100 m) line of sight.
The LEIT-2 controller requires daily exposure to light levels at a minimum of
3000 lux, which is equivalent to daylight around 7-8 AM on a cloudy day. On
very cloudy days the controller requires more time to charge up and to operate
with the radio.
IMPORTANT:
Communication between the LEIT RC2 handset and the LEIT-2
controllers are automatically limited to daylight hours when there is sufficient
light energy. Longer bright light days will enable the radio to operate
automatically over longer parts of the day, including through the night.
