A basic program requires a START TIME, station Run Time, and Water Days to operate automatically. This is where basic automatic irrigation is set up. There are 32 possible automatic irrigation programs with each operating up to 10 Start Times.

FLOW MANAGER runs simultaneous stations to reach a programmable flow rate target. It allows the controller to decide which stations to run, to keep the total flow as close to the pipe design capacity as possible, and shorten the overall watering time. Using this feature does NOT require a flow sensor, but it must have station flow values configured. If flow learning via a sensor is not available, approximate values may be entered manually.

A BLOCK is an electronic group of stations that runs at the same time, for the same run time, within a program (Blocks replace “SSGs” in original ACC).

USA

The primary use for this setting is to allow stations to be named. Most other functions are described in more detail in the Flow Operations section.

The ACC2 controller allows up to six Pump and/or Master Valve outputs to be assigned in the controller. This applies to the decoder and conventional models. In this article, the following topics are covered:

A new controller installation will begin with at least one or two ATTENTION messages, because the controller has experienced a "power outage" in shipping, and might be discovering new modules. This is normal. Messages on the screen do not interfere with normal irrigation.

When power is first turned on (either with the power switch, or closing one of the slide locks), the Hunter logo screen appears, and the controller begins searching for any irrigation events it may have missed during a power outage.

You can manually test proper operation of the rain sensor by using the One Touch Manual Start. During the Manual All stations cycle, press the test button on the “Clik-type” sensor (eg. Mini-Clik®) to interrupt watering.

Note: The rain sensor will only interrupt watering in Manual All Stations and automatic programming.  Manual single station will override the sensor circuit.

The most common reason for a valve to remain on, or weep, is debris. New installations without proper flushing, recent mainline repair, or well water can cause debris to flow into the valve and get caught between the diaphragm and the seat. Check for debris using the following steps:
