Page 4: Mounting The Hdc Controller
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.

bundled or wired together with all other common wires from all the valves to the “Com” terminal of the controller. 4) 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.
Page 6: Master Valve/Pump Start/Sensor
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...
Page 7 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 i s in the “ON” position and no sensor is connected.
Page 8 DEFAULT PROGRAM 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.) Should there not be sufficient battery power to maintain the real time clock and calendar and there is a power outage;...
Page 9: Programming The Controller
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).
Page 10 3) Calendar/schedule, days of week or ODD/EVEN days. 4) Individual station run times. INPUT THE CURRENT DATE AND TIME 1) Turn dial CURRENT DATE/TIME. 2) Use the + and – buttons to select the current year. Push the ? button to activate the month.
Page 11 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.
Page 12 scroll to 12:00 am/midnight. Then push the + button once to attain the “OFF” display. 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.

active day or non-circled. Press the “ -” button to change to a circled day, which indicates an inactive day. Press the ? button to advance to the next day. Repeat step 3 for each day of the week. The ? button may be used to advance to a particular day of the week.
Page 15: Manual Station/Program
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.

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.

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 –...
Page 18 The controller can now be programmed as if brand new. Note: This is recommended on new installations before programming for the first time.
