8. CONNECTING THE TRANSFORMER WIRE TO THE CONTROLLER
WARNING: Do not plug transformer into power source until the controller is mounted.
After connecting all valve wires and installing the battery, you are ready to connect the
transformer. Use only the supplied transformer, or a transformer with 110 VAC power input,
50 Hertz and 24 VAC output.
1. First, connect the transformer wire to the two terminals marked “24V”. (see figure below)
(Polarity does not matter).
2. Plug the transformer to 110 Volt electrical outlets.
Note: If power is
interrupted to the
controller when
irrigation is on, the
valve will close
automatically
and irrigation will
stop, although
the controller will
continue to operate
per the program.
9. PROGRAMMING
General Information
The GQ-AC controller is ready to program. Lift the cover and remove the plastic sheet that
protecting the LCD display. At this stage the user needs to program the controller.
Before programming the controller:
The GQ-AC controller has three irrigation programs, A, B, and C. In addition, it has an
additional support program, program X that can also be activated. The three programs (A,
B, and C) can be used to operate all the valves. In each program, days of watering can be
selected in which all the valves activated by one of the three programs. Start-time is set
only for the first valve on the system, with the irrigation duration being defined for each valve
separately. The valves are opened in sequence per their number as shown on the display
screen. When the first valve shuts down, the second valve opens up and so on. At any one
time only one valve operates. If the three programs are used (A + B + C) with irrigation times
which overlap, program A will open first and only after it shuts down, program B will open,
then program C opens last. Any of the valves can be operated by any of the three programs,
with differing durations under each program.
