CONTROLLER CONFIGURATIONS
This controller can operate four different iterations of ReWater's recycling irrigation systems,
thus there are slightly different controller configurations available. Those iterations are:
CA Compliant Greywater (110v)
City of LA Compliant Greywater (110vand 220v)
Rain Harvesting (110vand 220v)
Greywater & Rain for LID Compliance (110vand 220v)
If you have our California Compliant Greywater system, then the main body of this User’s Guide
pertains to your controller. If you have one of our other three iterations, any difference in your
controller configuration is addressed in alater section dedicated to that type of system.

GENERAL INFORMATION
This section contains general information on:
• How the backup system works
• How the electronic circuit breaker works
• How the sensor feature works
HOW THE BACKUP SYSTEM WORKS
The Complete Control uses non-volatile memory to store watering programs. This type of
memory prevents the watering program information from becoming lost in the event of a power
failure.
Because the current time and date are always changing, only the most recent date can be saved
in non-volatile memory. Therefore, a battery is required to maintain the correct time and date in
the event of a power failure. A 9-volt alkaline battery (provided) will maintain the correct time
and date during power failures up to 90 days. In a typical installation, the battery should last
from two to four years before replacement is necessary. Once the battery is installed, the
controller can be fully programmed for operation.
Note: For operation ofthe valves, AC power must be applied.
To install the battery:
1. Unlatchthehingedcontrolmoduleassembly
and carefully swing it outward to open.
2. Locate and remove the battery
compartment cover from the lower back
side of the module.
3. Connect the 9-volt alkalinebattery supplied
to the battery clip terminals.
4. Insert the battery into the compartment
and reinstall the battery compartment
cover.
Caution: Batteries contain hazardous material. Always handle and discard batteriesproperly.

HOW THE ELECTRONIC CIRCUIT BREAKER WORKS
The Complete Control is equipped with an electronic circuit breaker. If the controller
detects a short circuit, the shorted station (valve) will be turned off automatically. The display
will then flash "SHORT" and the shorted station number, or “RELAY,” “3-WAY,” “BW,” or “FW.”
The controller continues to automatically water the other stations and the following watering
programs until the shorted station is repaired. Each automatic start will attempt another cycle
and retest the short- circuited valve. Listed below are the most common conditions which
will activate the electronic circuit breaker. After correcting the problem, return the controller to
normal operation as follows :
1. Set the dial to one of the following positions: Run, Manual-Single Station or Manual-Program
Cycle.
2. Press the OFF button to return the controller to the normal operating mode.

Solution:
The word "SHORT" displays with one or more station numbers.
One or more stations are shorted.
Check the wiring of the displayed stations for the cause of the shorted condition.
Repair valve(s) and/or wiring as needed.
Too many valves operating at the same time causing an overload condition.
Check watering programs for concurrent station operation. Maximum total output
is 24 VAC at 1.25 amps. Reduce the number of stations running at the same time.
The word "SHORT" displays without one or more station numbers.
A short circuit has occurred with a time duration too short for the controller
to determine the station.
Check all valve wiring for breaks in the insulation which may cause a station output
to short to common.
A transient power surge spike has occurred.
Reset the controller.
A short or overload occurred on one watering cycle but was no longer there on
a subsequent cycle.
Check for loose and/or exposed valve wiring.

HOW THE SENSOR FEATURE WORKS
The Complete Control is equipped to operate with an optional rain sensing device, commonly
calleda "Rain Switch", to prevent automatic watering during rain .
The rain switch is a simple device, typically installed on a roof overhang or stationary structure
exposed to rainfall and full sun and shielded from irrigation spray.
When rain occurs, the normally closed rain switch senses the moisture and opens the valve
common circuit, effectively preventing all output to the field. The electronic programming
portion of the controller is isolated from the rain sensor switch, and continues to operate as
programmed. When rain stops and the rain switch returns to its normally closed state, the valve
common circuit is restored, allowing watering to resume as scheduled.
A two-position Sensor switch (see figure, item 20 on page 4) is provided to enable you to easily
bypass operation of the rain switch at any time. If you choose to disregard rain switch input,
place the SENSOR switch in the bypass position. To enable rain switch operation, place the
Sensor switch in the Active position.
IMPORTANT:
If a rain switch is NOT connected to the controller, the
SENSOR switch MUST be in the BYPASS position to enable controller
operation.
The controller will not operate automatically or manually if
the SENSOR switch is in the ACTIVE position without a rain switch
connected.
!
IMPORTANT:
The rain sensor willalso prevent the recycling function from
operating.
