2. The controller shall have a base station capacity of 50 stations with two additional
expansion slots capable of receiving ESPLXD-SM75 station modules to create a
controller capacity of up to 200 stations. All stations shall have the capability of
independently obeying or ignoring any weather sensor as well as using or not using the
master valves. Station timing shall be from 0 minutes to 12 hours. The controller shall
have a Seasonal Adjustment by program which adjusts the station run time from 0 to

of 0 to 300%by month. Station timing with Seasonal Adjustment shall be from 1 second
to 16 hours.
3. The controller shall have 4 separate and independent programs which can have different
start times, start day cycles, and station run times. Each program shall have up to 8 start
times per day for a total of 32 possible start times per day. The 4 programs shall be
allowed to overlap operation based on user-defined settings which control the number of
simultaneous stations per program and total for the controller. The controller shall allow
up to 8 valves to operate simultaneously per program and total for the controller
including the master valves.
4. The controller shall have a 365-day calendar with Permanent Day Off feature that allows
a day(s) of the week to be turned off on any user selected program day cycle. (Custom,
Even, Odd, Odd31, & Cyclical). Days set to Permanent Day Off shall override the
normal repeating schedule and not water on the specified day(s) of the week. The
controller shall also have a Calendar Day Off feature allowing the user to select up to 5
dates up to 365-days in the future when the controller shall not start programs. The
controller shall incorporate a Rain Delay feature allowing the user to set the number of
days the controller should remain off before automatically returning to the auto mode.
5. The controller shall have water management software which is capable of operating each
station for a maximum cycle time and a minimum soak time to reduce water run-off. The
maximum cycle time shall not be extended by Seasonal Adjustment.
6. The controller shall incorporate a management feature providing real-time flow, power,
and station management. This feature shall manage the number of stations operating at
any point in time based on water source capacity, station flow rate, number of valves per
station; user defined simultaneous stations per program and for the controller. The
controller shall provide station priorities to determine the order in which stations shall
operate. The controller shall ignore the station number and instead operate the highest
priority stations first and the lower priority stations last.
7. The controller shall offer water windows for each program. This function sets the
allowed start and stop time where watering is allowed. If the watering cannot be
completed by the time the water window closes, the stations with remaining run time are
paused and watering automatically resumes when the water window opens the next time.
8. The controller shall offer a sensor option which adds flow sensing functionality. The
sensor input shall accept a direct input from a flow sensor with no flow scaling device
required.
9. Module features shall include a utility which learns the normal flow rate of each station.
Each time the station runs the utility compares the current real-time flow rate to the
10 Planting Irrigation
RIVERSIDE HORIZONS DEVLOPMENT
learned rate and takes user defined actions if high flow, low flow, or no flow is detected.
Flow rate utility shall automatically determine the location of the flow problem and
isolate the problem by turning off the affected station or master valve. The flow utility
shall be compatible with both normally closed and open master valves. A manual master
valve water windows shall be provided to coordinate daytime manual watering with the
flow sensing. This water windows shall offer programmable days of the week and
manual watering additional flow rate.
10. The controller shall be compatible with an ET manager cartridge which upgrades the
controller to a Smart Controller (weather-based). A weather service signal received by

station run times to apply the minimum amount of water required based on the current
plant water requirements.
11. The controller shall have a cabinet and pedestal suitable for exterior applications.
