CONNECTING VALVE WIRES TO CONTROLLER
MOUNTING THE HDC CONTROLLER

3)
Remove lower panel cover.
Connect one wire from each valve to the desired
corresponding number on the terminal.
Connect the remaining valve wire from all the valves
to the “Com” or common terminal. It is suggested
to use a dierent color wire for the common wire
to help keep organized. “Common” wires may be
bundled or wired together with all other common
wires from all the valves to the “Com” terminal of
the controller.
CONNECTING VALVE WIRES TO CONTROLLER
Locate controller within 5 . of a standard electrical
outlet that provides continuous, uninterrupted power.
Do not install controller within 15 . of a pump, pump
start relay or any high voltage junction boxes or elec-
tric motors.
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.

MOUNTING THE HDC CONTROLLER

Note: All in-eld wire splices should be made using
a dry type waterproof, gel-lled Hit Products DBC-Y
type connector or equivalent.
4)
5)
Wire sizing should be of signicant size to allow a
maximum of 5 volts drop between controller and
valves. Use Ohms’ Law to calculate wire voltage
drop.
Replace cover.
Leave electrical power unattached until all valve
wires are connected to the controller.
Remove lower panel cover to gain access to the
terminal connectors. Insert the two wires from
the plug-in transformer into the two terminals
m a r k e d ‘A C ’ “A C ”.
Replace cover.

MASTER VALVE/PUMP START WIRING
If a master valve or pump start relay is being used in
conjunction with this controller, wire as follows.
Hit Products oers a wide range of pump start relays
for most applications that are compatible with the
HDC controller.
Note: DO NOT connect controller directly to pump.
Controller will be damaged if controller is connected
directly to pump.
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.
Connect one wire to the “MV” terminal and one
to the “Com” terminal.
If using a pump start relay, it must be;
1)
2)

Remove lower cover.
Route the 2 wires from the sensor to the bottom of
the controller and connect one each wire to the two
“RS” terminals.
If the “RAIN SENSOR” switch on the front of the
faceplate is in the “ON” position and no sensor is
connected. e display will show a ashing “SEN
SOR” and no irrigation will occur. To override the
problem when no sensor is connected-always leave
the “RAIN SENSOR” switch on the front panel in
the “OFF” position.

3)
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.

DEFAULT PROGRAM, POWER
FAILURE,
LOW BATTERY OR
NO BATTERY INSTALLED
e controller does not require a default program aer
a power outage. e controller has non-volatile memory
to retain your custom program. Four AAA Alkaline bat-
teries maintain the real time clock and calendar.
(Batteries should be changed annually.)
Should there not be sucient battery power to maintain
the real time clock and calendar and there is a power
outage; when the electrical power returns, the controller
will default to midnight and Saturday.

Note: e 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 CURRENT CONDITION
NOPO No AC power to controller
LOBA Low battery or no battery
NOPO will blink on-o it no AC power is available
and battery is installed and charged.
LOBA will blink on-o if low battery or no battery.
Rotating the dial will stop blinking for one minute and
display will return to normal for programming or to
review program.
Display will return to blinking aer one minute if low
battery or no battery condition exists. If LOBA ashes
aer a power disruption, the clock and calendar may
have to be reset, as no AC power or battery power was
available to keep real time.

PROGRAMMING THE CONTROLLER
To successfully program controller, all three programming
elements must be completed.
ey are:
8
9
Program Start Times (Time of day a complete
programmed irrigation cycle will start).
Station Run Times (e length of time each
station/valve will irrigate).
Calendar/Schedule (e days of week/calendar
that you desire to irrigate).

BASIC PROGRAMMING FEATURES
To program the controller, you are provided + or – buttons
that will change the value of the “Flashing display”. e
 or  change the subject of information that is ashing.
e subject or “Flashing display” is in sequence and can
be scrolled forward  or backward  to access all desired
programming options.
ree independent programs are available
“A”, “B” and “C”.
ree program start times are available per
program.
Calendar/schedule, days of week or ODD/
EVEN days.
Individual station run times.
