Receiver Installation, Other Controllers (continued):
C. 24 Volt Solenoid Valves with Booster Pump (See Figure 5)
Locate the common wire to the
solenoid valves and the common wire
leading to the coil of the relay that
starts the pump. If these two wires are
connected to the “common” terminal
on the controller, disconnect both
of them.
Twist together these two wires along
with one wire from the Rain-Clik™,
and secure with a wire nut. Attach
the other wire of the Wireless Rain-
Clik™ receiver to the “common”
terminal on the controller. Note: The
pump circuit output must be 24 Volts
in this situation. Do not proceed
if 110V.
SETTING THE TRANSMITTER ADDRESS AT THE RECEIVER
Units purchased as a kit will already have their address learned.
No addressing is necessary, however if the receiver or transmitter is
replaced, you need to reset the address.
Each transmitter produced has a unique address hard-coded into it. A receiver
must learn this address to work with that transmitter. This step will only be
necessary if transmitters and receivers are purchased separately.
1. Prior to applying power (yellow wires) to the receiver, press and hold the
pushbutton on the receiver.
2. While the pushbutton is being held apply power to the receiver–the
receiver’s “sensor status” LED should light up yellow indicating the receiver
is ready to learn an address.
3. Push and hold the quick response post on the transmitter/sensor.
4. Within 4 seconds, the receiver’s “sensor status” LED should turn red.
5. Release the transmitter/sensor’s quick response post and within 4 seconds
the LED on the receiver should turn green. The address is now learned and
will be retained even in the event of a power outage.
OPERATION
The receiver has two LEDs, which indicate the state of the system. The
STATUS LED will be RED when the sensor is wet (watering disabled), and
GREEN when the sensor is dry (watering enabled). There is also a RED
BYPASS LED on the receiver. If this LED is lit, the rain sensor is bypassed
and watering will always be allowed. Even though the sensor is bypassed, the
STATUS LED will continue to alert you of the state of the sensor (Wet or Dry).
ADJUSTMENTS AND OPERATION
The Wireless Rain-Clik can keep the irrigation system from starting or
continuing after rainfall or freezing conditions (Wireless Rain/Freeze-Clik).
The time that it takes the Wireless Rain-Clik to reset for
normal sprinkler operation after the rain has stopped
is determined by weather conditions (wind, sunlight,
humidity, etc.). These conditions will determine how fast
the discs dry out, and since the turf is also experiencing
the same conditions, their respective drying rates will
roughly parallel each other.
There is an adjustment capability on the Wireless Rain-
Clik that will slow down the reset rate. By closing the
“vent” (see Figure 6) to completely or partially cover
the ventilation slots, the discs will dry more slowly.
This adjustment can compensate for an “overly sunny” installation location, or
peculiar soil conditions. Experience will best determine the ideal vent setting.
No adjustment is required for the freeze sensor portion of the wireless
Rain/Freeze-Clik. The Wireless Rain/Freeze-Clik will automatically disable
the Irrigation system when temperatures fall below 37°F. Although Freeze
Sensors are designed to automatically prevent watering near or below freezing
conditions, visual checks and prudent manual watering suspensions should be
used in conjunction with any freeze sensor
BYPASSING THE SENSOR
The sensor may be bypassed by using the built in bypass feature in the SRC,
Pro-C or ICC. On other controllers the sensor may be bypassed by pressing the
“BYPASS” button on the receiver. The RED BYPASS LED on the receiver will be
lit when the sensor is bypassed. Pressing the “BYPASS” button again will cause
the RED BYPASS LED to go back out thus re-enabling the sensor.
Battery Life: The Wireless Rain-Clik transmitter is designed to work daily for
up to 12 years with the maintenance-free battery. The sealed unit is available
as a replacement part. Should you need to change the transmitter the receiver
will have to learn the new transmitter address.
There is no required maintenance for the unit. The Wireless Rain-Clik does not
have to be removed or covered for “winterizing” purposes.
TROUBLESHOOTING
Follow these simple checks first before assuming the unit is bad and replacing it.
System will not come on at all:
A. First, check to see that the Wireless Rain-Clik discs are dry and the switch
“clicks” on and off freely by pressing the top of the spindle.
B. Next, look for breaks in the wire leading to the Wireless Rain-Clik receiver
and check all wire junctions.
C. Verify temperature (for Rain/Freeze-Clik installations).
System will not shut off even after heavy rainfall:
A. Check wiring for correctness (see section on wiring to your irrigation system).
B. Is the rainfall actually hitting the Wireless Rain-Clik? Check for obstructions
to rainfall such as overhangs, trees or walls.
