Frequently Asked Questions - 102P3N Irritrol

How do I set the watering program on the 102P3N?

Turn the dial to Set Program. Use the + and - buttons to select program A, B, or C. Then set start times and duration for each station.

How can I manually start a station?

Turn the dial to Manual. Then press the + or - button to select the station and press Enter to start.

What does the rain sensor do?

When a compatible rain sensor is connected, the controller automatically skips watering when rain is detected, saving water.

How do I set a rain delay?

Turn the dial to Rain Delay. Press + or - to set the number of days (1-99), then press Enter. Watering will resume after the delay.

Why is my controller not turning on?

Check the power supply (transformer plugged in and outlet working). Also inspect the fuse inside the controller; replace if blown (0.5A 250V).

How do I connect a rain sensor?

Connect the two wires from the rain sensor to the Sensor terminals (labeled SEN) on the back of the controller. Ensure the sensor is normally closed.

How do I reset the controller to factory defaults?

Turn the dial to System Setup. Press and hold the + and - buttons simultaneously for 5 seconds until the display resets.

What is the maximum watering duration per station?

You can set a duration from 1 minute to 99 minutes for each station in the program.

How do I winterize my controller?

Turn off the master valve and drain the system. Set the controller to Rain Delay for the winter months or disconnect the power.

Where can I find replacement parts?

Replacement fuses and transformers are available from Irritrol dealers. Contact customer support for genuine parts.

100 / 100-S Series Valves

Installation Instruction

Introduction

100 Series Valve

Built on proven technologies and components, the Irritrol 100 Series valves are tough, have excellent performance, and are extremely reliable. A self-cleaning metering system and 220 PSI rating assures years of trouble-free performance.

100S Series "Scrubber" Valve

Constructed of heavy-duty, glass-reinforced nylon, high grade stainless steel, brass and EPDM rubber materials, the 100 Series scrubber valves resist clogging. The patent-pending continuous scrubbing mechanism actively fights dirt, algae and other particles from disrupting the functionality of the valve. The 100 Series scrubber valves are true dirty water irrigation valves, able to handle the harsh chemicals found in dirty water systems, such as chlorines, chloramines and water treated with ozones.

Installation Recommendations

• In commercial installations, it is advantageous to install the valves in a valve box. This enables the valve to be easily located, accessed, and maintained.
• Partially fill the bottom of the valve box with clean aggregate to facilitate drainage.
• Locate the valve box away from structures, hardscape features (such as sidewalks), and large planting locations.
• Locate the valve box in shrub beds and at right angles to structure locations.
• If valves are installed below grade without a valve box, access to the top of the valve should be provided by using a section of 4" PVC pipe and a valve cover installed directly over each valve.

Features

100 Series Valve

• 220 PSI maximum pressure rating
- Removable, self-cleaning metering system
- Precise pressure control with optional Omni-Reg® pressure regulator (field installed)
- Manual flow control: adjustable to zero flow
- Internal manual bleed screw: bleeds internally downstream
- External manual bleed screw: bleeds to atmosphere, allows cleaning of metering rod and provides maximum flushing

100S Series "Scrubber" Valve

• All the great features of the 100 Series valve.
• Continuous scrubbing turbine actively cleans the metering device for consistent valve operation in dirty water applications.

Installation Guidelines

Using pipe dope on valve connections can cause thread damage and failure of the valve body.

Use only PTFE tape or pipe thread sealant.

• Note the flow direction arrows on the bonnet or body and install accordingly.
• The valve can be installed at any angle without affecting operation.

• The valve body plug and o-ring must be properly installed in the unused inlet.

• Use direct-burial wire, utilizing different color codes for each station control wire and one color for the common wire to all valves.

• Waterproof wire splice connectors are absolutely essential for proper electric control system operation. Follow the installation instructions provided with the connectors for optimum waterproof splice protection.
• Leaving a wire expansion loop at each valve location on long-run wire lengths is recommended.

Valve Operation

Flow Control

Flow control reduces the flow and pressure to valve outlet. By turning the control handle clockwise, the flow will be gradually reduced to zero.

Internal Manual Bleed Knob

The internal manual bleed system is used to manually operate the valve. Turning the internal bleed knob (located beneath the solenoid) counterclockwise allows water to bleed downstream from the diaphragm chamber. Internal

pressure is relieved from the top of the diaphragm, allowing the valve to open. Turning the bleed knob clockwise until tight shuts off the discharge enabling pressure to build within the diaphragm chamber, causing the valve to close.

External Manual Bleed Knob (flush mode)

The external manual bleed knob, located on top of the flow control handle, is used for system flushing. Turning this knob counterclockwise allows water in the diaphragm chamber to vent to atmosphere, creating maximum opening power and debris flushing action. This operation bypasses the regulator (if installed) and opens the valve fully, regardless of regulator setting. In addition, the metering rod (attached to the external bleed knob) can be easily removed for cleaning as necessary.

100S Scrubber Operation

Continuous scrubbing turbine actively cleans the metering device for consistent valve operation in dirty water applications.
