Controller Installation

Installing the Cabinet

1. For safe and reliable operation, select an installation site which can ideally provide the following conditions:

2. For Indoor model controllers – Inside a garage or other structure which will provide protection from the weather.

3. For outdoor model controllers – Protection from irrigation spray, wind and snow. A shaded location is recommended.
4. Access to a grounded AC power source (within 4' [1.2m] for indoor models) which is not controlled by a light switch or utilized by a high current load appliance, such as a refrigerator or air conditioner.

5. Access to the sprinkler control valve wiring and optional accessory wiring.

6. Drive a wood screw (provided) into the wall at eye level. Leave the screw extended approximately 1/4" (6mm) from the wall. See Figure 1.
   Note: If installing the controller on drywall or masonry, install screw anchors.

7. Remove the lower cabinet access cover by pressing it on the bottom and pulling it directly outward from the cabinet.
8. Hang the cabinet on the screw using the keyhole slot on the back panel. Make sure the cabinet slides down securely on the screw.
9. Install the lower mounting screw and tighten securely.

Note: Conduit and adapters are not provided. Install conduit as required by local electrical codes.

1. Remove the power wire access cover. Remove the conduit knockout according to the size of conduit being used. Install 1/2" (13mm) conduit for power/equipment ground wires (outdoor models only) and 3/4" (19mm) or 1" (26mm) conduit for valve wires (all models).

Technical line drawing of a mechanical enclosure with screws and mounting holes, labeled as Figure 1 (no text or symbols on the diagram itself)

Installing the Valves

CAUTION: Maximum screw torque not to exceed 5 in-lbs.

1. Route the valve wires or wire cable from the valves, into the controller cabinet.
   Note: 18AWG (1.0mm2) multi-wire sprinkler valve connection cable can be used. This cable is insulated for direct burial and is color-coded to simplify installation. It can be routed directly into the controller through the access hole provided for valve wire conduit (if conduit is not used).
2. Attach the white color-coded wire from the cable to one wire from each valve solenoid. (Either solenoid wire can be used for this connection.) This is called the "Valve Common" wire. See Figure 2.
3. Attach a separate cable wire to the remaining wire from each valve solenoid. Note the wire color code used for each valve and the watering station it controls. You will need to have this information when connecting the valve wires to the controller.
4. Secure all wire splices using wire nut connectors. To prevent corrosion and possible short circuits, always use an insulated wire nut, grease cap or similar waterproofing method.
5. At the controller end of the valve connection cable, strip back 1/4" (6mm) of insulation from all cable wires
6. Secure the Valve Common wire to the terminal labeled COM. Connect the individual valve wires to the appropriate station terminals. Connect the master valve wire (if applicable) to the terminal labeled MV.

Note: Connecting a master valve or pump start relay is optional and may not be required for your sprinkler system.

Installing a Pump Start Relay

CAUTION: To prevent controller damage, ensure the pump start relay current draw does not exceed 0.4A. Do not connect the pump motor starter directly to the controller.

1. Connect a wire pair to the 24VAC pump start relay. Route the wires into the controller housing with the valve wires.
2. Connect one wire to the terminal labeled COM. Connect the remaining wire to the terminal labeled MV. See Figure 2.

CAUTION: To prevent pump damage due to "Dead-heading," connect a jumper wire from any unused station terminal to a station terminal with a valve connected.

Installing a Rain Sensor (optional)

A rain sensor can be connected directly to the KD2 to automatically interrupt watering when it begins to rain. When the rain sensor absorbs rain water, it automatically signals the KD2 to suspend all watering operations. The display will alternately show SEN (sensor) and the time of day until the rain sensor drys out and resets the controller for automatic operation.

1. Route the wire cable from the rain switch sensor into the controller along with the valve wires.
2. Remove the jumper wire from the sensor terminals.

3. Referring to the instructions provided with the rain sensor, connect two wires from the rain sensor designated for "Normally Closed" applications to the sensor terminals. See Figure 3.

4. Once powered, turn the dial to special Functions. Press and scroll to RS Y (Rain Sensor Yes). Press + / -to set sensor to RS Y (active) or RS N (Bypass).

Note: The default setting is RS Y (active).

Connecting the Power Source

WARNING

AC power wiring must be installed and connected by qualified personnel only. All electrical components and installation procedures must comply with all applicable local and national electrical codes. Some codes may require a means of disconnection from the AC power source installed in the fixed wiring and having a contact separation of at least 0.120" (3mm) in the line and neutral poles. Make sure the power source is OFF prior to connecting the controller.

1. Verify that the power is turned off at the source.
2. Remove the power connection access cover.
3. Route the power and equipment ground wires from the power source through conduit into the controller power connection compartment. For wire restraint, route the cable inside the compartment as shown in Figure 4 A.
   Note: The international model terminal block accepts wire size up to 4 mm ^2 .
4. For non-US models, use the terminal block which accepts wire size up to 4 mm^2 (Brown for line, Blue for neutral and Green for earth ground). For US models, use the wire nuts provided, secure Line to the Black wire, Neutral to the White wire and Equipment Ground to the Green wire. See Figure 4 B and C.

5. Install and secure the power wire access cover.

6. Apply power to the controller. The controller needs about 60 seconds to internally charge before station outputs can operate. This will only occur when the controller is initially powered up or after a power interruption.

See Setting the Date and Time on page 7 to set the current time and date. To quickly check sprinkler system operation, refer to the Test Mode procedure.

Planning Your Watering Schedule

It is often helpful to plan your watering schedule on paper before beginning the programming steps. The information can then be transferred to the Quick Reference Card as a handy reference.

Filling out the Watering Schedule Form

When filling out the form provided on page 10, use a pencil so changes can be easily made.

Refer to the example shown on the opposite page and fill out your form in a similar manner. Include the following information:

• Location - Identify the location of each watering station area and the type of plant being watered.
  Note: Enter the following information for each program. If the program is not needed, leave its information column blank.
• Watering Day Schedule - For a Calendar schedule, indicate which day(s) of the week watering is desired. For a Day Interval schedule indicate the desired Interval number (1–31). For Odd or Even day watering schedule, simply mark the appropriate box.
• Station Run Time Duration - Indicate the amount of run time (1 minute to 4 hours) for each station. Write "Off" for any station which you do not want to run in the program.
• Program Start Times - Indicate the time(s) of day to start the program. Each program can have up to three start times per watering day.

⚠️ Important: The KD2 can run only one program watering cycle at a time. Therefore, when setting more than one start time for a program or when setting up more than one program, make sure that each program watering cycle will be able to run completely before the next start time occurs. This can be easily determined by totaling up the run time duration of all stations that will operate during the program, then selecting the next start time that can accommodate the completion of the initial watering program. If Water Budget is used to increase run time duration, this must also be considered in the total run time. It is important to remember that a program start time which occurs while a watering cycle is in progress will be delayed (stacked) until the current watering cycle is finished. If this happens, it may appear that the sprinklers are not shutting off or that they are running at an unexpected time of day.

Firmware Version

To check your KD2's firmware version, place the control dial to 🖱️ Special Functions position and press the ➕ button as needed until the firmware version is displayed (V001 or later).

Automatic Circuit Breaker

The KD2 controller features an electronic circuit breaker which automatically detects an overload condition on a station terminal during operation and turns off the station before controller damage can occur. The KD2 advances to the next programmed station in sequence to continue the watering cycle.

After the program watering cycle has finished, FUSE and the number of the skipped station(s) will be displayed in alternating sequence with the current time of day. If all of the station numbers and FUSE are displayed, the master valve is malfunctioning. Pressing any button will remove the warning display.

⚠️ Important: The most common cause of an overload condition is a short circuit in the valve wiring or a malfunctioning valve solenoid. The cause of the overload condition should be corrected before continuing to operate the controller.

Troubleshooting

Symptom	Probable Cause	Remedy
Display is blank and controller does not operate.	Power is disconnected.	Check transformer connections (indoor models). Check the AC service panel for a tripped circuit breaker or GFI and reset.
Valve does not turn on.	Faulty control valve wire connections.Sensor switch in Active position without a sensor or jumper installed.No station run time duration set.	Check the wire connections at control valve and controller.Set sensor switch to Bypass position or add jumper to sensor terminals.Check station run times. See page 12.
Valve does not turn off.	Control valve problem	Inspect, clean and/or replace the valve solenoid and/or diaphragm.
Watering program(s) start at unexpected times.	Watering program schedules have overlapping start times.Water Budget setting over 100% can cause delayed start times.	Check program start time schedules.Shorten station run times and/or space start times farther apart.Check Water Budget and decrease adjustment % factor as necessary.
Controller not watering on the selected active day.	Rain Delay is active.Interval or Odd/Even Mode.	Check if Rain Delay is set.Check if Interval or Odd/Even mode is selected and see if the selected day falls within the Odd, Even or falls between the interval watering schedule.
