MOUNTING THE HDC CONTROLLER 1) Locate controller within 5 ft. of a standard electrical outlet that provides continuous, uninterrupted power. Do not install controller within 15 ft. of a pump, pump start relay or any high voltage junction boxes or electric motors. 2) Choose desired location and install one screw for top keyhole into wall. Remove bottom panel and insert two additional screws in each of the bottom corners in the holes provided. Use screw anchors if attaching to drywall or masonry.
) Wire sizing should be of significant size to allow a maximum of 5 volts drop between controller and valves. Use Ohms’ Law to calculate wire voltage drop. 5) Replace cover. Note: All in-field wire splices should be made using a dry type waterproof, gel-filled Hit Products DBC-Y type connector or equivalent. CONNECTING POWER SOURCE 1) Leave electrical power unattached until all valve wires are connected to the controller. 2) Remove lower panel cover to gain access to the terminal connectors.
MASTER VALVE/PUMP START WIRING If a master valve or pump start relay is being used in conjunction with this controller, wire as follows. 1) Connect one wire to the “MV” terminal and one to the “Com” terminal. 2) If using a pump start relay, it must be; a) Located at least 15 feet from controller. b) Have a maximum rated inrush current less then 350MA at 24 VAC, and be properly sized for your application.
SENSOR WIRING A rain sensor or any other type of normally closed micro-switch sensor may be used in conjunction with this controller. Sensor activation will interrupt controller output. 1) Remove lower cover. 2) Route the 2 wires from the sensor to the bottom of the controller and connect one each wire to the two “RS” terminals. 3) If the “Rain Sensor” switch on the front of the faceplate is in the “ON” position and no sensor is connected.
DEFAULT PROGRAM, POWER FAILURE, LOW BATTERY OR NO BATTERY INSTALLED The controller does not require a default program after a power outage. The controller has non-volatile memory to retain your custom program. Four AAA Alkaline batteries maintain the real time clock and calendar. (Batteries should be changed annually.
Note: The controller will Run scheduled programs according to the displayed Day and Time. You will need to reset the controller to current time and calendar. DISPLAY NOPO LOBA CURRENT CONDITION No AC power to controller Low battery or no battery NOPO will blink on-off it no AC power is available and battery is installed and charged. LOBA will blink on-off if low battery or no battery.
PROGRAMMING THE CONTROLLER To successfully program controller, all three programming elements must be completed. They are: Program Start Times (Time of day a complete programmed irrigation cycle will start). Station Run Times (The length of time each station/valve will irrigate). Calendar/Schedule (The days of week/calendar that you desire to irrigate).
To program the controller, you are provided + or – buttons that will change the value of the “Flashing display”. The ← or → change the subject of information that is flashing. The subject or “Flashing display” is in sequence and can be scrolled forward → or backward ← to access all desired programming options. BASIC PROGRAMMING FEATURES 1) Three independent programs are available “A”, “B” and “C”. 2) Three program start times are available per program. 3) Calendar/schedule, days of week or ODD/ EVEN days.
INPUT THE CURRENT DATE AND TIME 1) Turn the dial to the CURRENT DATE/TIME. 2) Use the + and – buttons to select the current year. Push the → button to activate the month. 3) The month will be flashing. Use the + and – buttons to select the current month. Press the → button to set the day. 4) The day will be flashing. Use the + and – buttons to select the current date. Push the → button to set current time. 5) The time will be displayed. Use the + and – buttons to select the current AM or PM hour notation.
SETTING PROGRAM START TIMES 1) Rotate the dial to program “START TIMES”. 2) Choose program A, B or C. To change program from existing program, push the PRG button. 3) Use the + and – buttons to adjust to desired start time. Start times are available every 15 minute increment of the hour. This represents the time of day the irrigation cycle will commence.
7) If two or more programs are to start at the same time, only the first program will start and run. At the completion of that program running, the next program will run, and so on until all multiple start times are run. This is called “stacking”. ESTABLISHING INDIVIDUAL STATION RUN TIMES This is the setting for establishing how long each independent “valve” or “station” will be on to irrigate. Each station will come on in numeric sequence for this duration as set for each Station Run Time.
4) Press the → button to go to the next station. 5) Repeat steps 3 and 4 for each station that is to be active on each specific program. For stations/valves that are to be inactive on each specific program, put “Station Run Time” at “0”. 6) Each individual “Station Run Time” can range from 1 minute to 6 hours in duration. 7) Rotate dial to “RUN” to enter this new data into controller. SETTING THE CALENDAR 1) Rotate dial to the Calendar/Schedule position. 2) Choose program A, B or C.
4) Repeat step 3 for each day of the week. The → button may be used to advance to a particular day of the week. To operate “odd” or “even” days of the month, continue advancing the → button and then activate “odd” or “even” as described in step 3 above. DIAL POSITIONS AND FUNCTIONS “RUN” Rotate the dial counter clock wise to the “RUN” position after completing any programming to enter this new data in controller. Leave the dial in the RUN position to have the controller operate as programmed automatically.
MANUAL STATION To manually activate a single station for one watering cycle for a programmed length of time. 1) Rotate dial to “Manual Station”. 2) Push → to desired station number. 3) Push + or – buttons to input length of time, this station will now operate this programmed time. 4) Rotate dial to “RUN” position, valve will now turn on. 5) Upon completion of this station operating manually for length of time programmed, controller will revert back to “RUN” and operate as previously programmed.
3) Push the → button to choose the first station in the sequence of the manual program to start. 4) The “run time” for each station will be displayed as currently programmed. For this cycle only, you can customize each station run time without effecting the individually programmed station run times within a program. 5) Push the → button to sequence through all the stations, using the + or – buttons to select the desired run times for this cycle only.
SEASONAL ADJUST The seasonal adjust feature provides a one step universal run time adjustment in 10% increments up or down for all programs. It effects all station run times in all programs. In hotter, drier weather, you can increase the water budget in 10% increments up to 200% of originally programmed station run times. In periods of cooler/wetter weather, you can water budget downwards – in 10% increments to as low as 10% of originally programmed station run time.
RE-SETTING OR ERASING CONTROLLER MEMORY If you want to eliminate all past programming input to controller, as if to start over as new, with no data in controller, proceed as follows: 1) Press the →, the – button and the PRG buttons simultaneously. 2) Controller will now display 12:00 a.m. and all the entered data has been erased. The controller can now be programmed as if brand new. Note: This is recommended on new installations before programming for the first time.
TROUBLE SHOOTING GUIDE No Display information. Check AC Power Supply, power at the controller should be 24-26 VAC. Check AC wiring. Check power at wall plug. Display reads “Sensor Off ”. Slide Rain Sensor switch to “off ” or install a sensor jumper wire on terminal strip connecting “RS” and “RS” terminals. Controller is irrigating at incorrect start time. Check Programming, Day, Time, AM-PM. Start Times and Active Day. Controller is operating properly but valve or valves do not activate.
