The TMC-424E Series takes modularity to a whole new level. Toro’s advanced

modular technology combines sophisticated features with simple operation to

provide a customizable controller. Station count can be 4 – 24 stations, using four-

or eight-station modules. Real-time flow sensing monitors up to three independent

sensors and is compatible with the Toro TFS Series flow sensors. Versatile run

times allows for additional watering flexibility. Add this together with features like

two levels of surge protection, compatibility with the TMR-1 Maintenance Remote,

the rugged dual-use cabinet, and convenient program review feature, and you

really do have the ultimate in controller Flexibility.

TMC-424E controller features:

• Advanced hybrid control module featuring easy-to-use dial interface

• Non-volatile memory–retains program data without battery backup

• Four fully-independent watering programs

• Concurrent operation of up to three automatic programs

•16 unique start times allotted to programs in any combination of 0–16

•Program cycle and soak option provides 1–30 repeat cycles and soak time

delay from 1 second to 60 minutes

•Day scheduling by Calendar days, 1–31-day Interval or Odd/Even days with

selective day exclusion

• Station run time adjustable form 1 second to 8 hours

• Season Adjust by program and by month from 0–200% (automatic split-cycle

watering for adjustment over 100%)

•Rain delay to postpone automatic watering operation from 1–14 days

• Master valve/pump start operation assignable by program or station

• Programmable well recovery/station delay from 1–60 seconds or 1–60 minutes

•Flow monitoring and alert parameters for 1– 3 flow sensors.

•Output current watchdog feature detects overload/short-circuit condition and

automatically bypasses suspect station(s).

• Optional Normally Open master valve control on flow sensing modules

•Manual operations by station and program

• Review feature quickly recaps all program information

• 12-or 24-hour time designation

• Programming display prompts selectable in English, Spanish, French,

German, Italian or Portuguese

• Valve test feature for quick station and system check

•Equipped for optional Toro rain sensor models TRS, TWRS and TWRFS,

Toro TMR-1 handheld maintenance remote and Toro TFS Series flow sensors.

Introduction

TMC424_UGE_466A 1/22/08 5:00 PM Page ii

The unique TMC-424E Expansion Modules are color-coded for easy identification.

The modules can be mixed and matched in any combination and are available in

six models as indicated in the table below.

The Expansion Modules can be installed and removed at any time without powering

down the controller. The TMC-424E will gain instant access to the module and will

logically number the stations based on module position.

For example, if three 4-station modules are installed, the stations will be numbered

1–12: module I(stations 1–4) module I I (stations 5–8) and module I I I ( s t a t i o n s

9–12). If module I I is removed, stations 5–8 will be automatically assigned to

module I I I.All stations will remain in sequence without gaps.

Getting Started

As an initial step, we recommend that you take a few moments to browse through

various sections of this User’s Guide. Also, take the time jot down some basic

watering program and station information on the Watering Schedule form provided.

Having this information readily at hand will be very helpful during the initial controller

setup and programming procedures.

Note that the Watering Schedule form provides a convenient pocket for the User’s

Guide and Quick Reference Guide when folded and attached to the inside of the

cabinet door.

What is a watering program?

In basic terms, a watering program is a small set of instructions that tells the

controller which days will be active for watering, when to start a watering cycle, and

how long each station will operate during the cycle. The TMC-424E series has four

independent watering programs identified as A,B,C, and D.

Separate programs are usually used to group stations with similar landscape or

watering attributes or to provide a way to segment specific site conditions, such as

north-facing slopes or shaded turf areas. As you can see, the availability of four

programs allows you to have unique watering programs for your varied landscape

needs. Multiple programs can be designated to operate one at a time or can

overlap operated in sequence or concurrently with up to three programs at the

same time.as you choose. This feature enables more watering to be completed

within the prime watering time, which is generally between midnight and 6:00 a.m.

What is a program watering cycle?

When a program start time is selected, that time becomes the beginning of an

automatic watering cycle. A watering cycle operates each station with an

assigned run time duration in the program, one by one, in numeric sequence

from the lowest to the highest station number.

The TMC-424E provides up to 16 watering cycle start time slots that can be

assigned to the four programs in any combination. For example, program A

could have 10 start times, program Btwo start times, program Cfour start times

and program Dno start times. Any combination up to 16 start times is permitted.

NOTE: A Watering Schedule Form is provided for your convenience. Use this

form to plan and record your automatic watering information. Keep the card

handy for reference by attaching it inside the cabinet cover.

What is Armchair ProgrammingTM?

A9V battery can be installed, enabling the control module to be fully

programmed prior to installation – in the comfort of your favorite easy chair.

1. Slide and lock the expansion module(s) into position.

2. Attach a 9V battery to the control module battery clip and stow the battery in

the slot provided. (See item 5 on page 3.)

3. With the Function Dial in the RUN position, press the button to acquire

the expansion module configuration (note the displayed module identifier).

4. To remove the control module from the cabinet, disconnect the ribbon cable

at the cabinet, then press the top hinge in to release the module.

5. Program the controller starting at Setting Current Time and Date on page 6.

NOTE: The 9V battery powers the microprocessor during an extended AC inter-

ruption. Once programmed, the battery can be removed or remain installed as

preferred. Controller output requires AC power input.

Programming Overview

TMC424_UGE_466A 1/22/08 5:00 PM Page 5

NOTE: English display prompts and 12-hour (a.m./p.m.) time format are factory-

default settings. To select an optional display language, including Spanish, French,

Italian, German and Portuguese, and/or a 24-hour time format, refer to the Special

Function setup procedures on page 13.

Set Current Time and Date

1. Turn the Function Dial clockwise to Current Time/Day . The hour digits will

begin flashing.

2. Adjust the display by pressing the or buttons.

NOTE: Hold either button down for rapid advance.

3. Press the button to select the next field.

4. Repeat steps 2 and 3 to set the current minutes, year, month and day

(current weekday will be set based on calendar setting).

5. Return the Function Dial to RUN when finished.

Select the Program

NOTE: If the controller has been previously programmed, the user-defined

program settings can be quickly erased and reset to factory defaults. See “Using

the Program Memory Erase Feature” on page 13.

To simplify the programming process, the following procedures are provided to

define the operating parameters of one program at a time.

To begin, set the program switch to select program A,B,C, or D.

Set Station Run Time

Astation is assigned to the selected program when it is given a run time

duration. The station can have only one run time assignment per program, but

can have a separate run time assignment in each program. By default, station

run time is defined in minutes and hours. To enable station run time to include

seconds, see “Station Runtime Display Format” on page 13.

1. Turn the Function Dial to Station Times .

2. Press the or button to select the station number.The corresponding

station output terminal will be shown on the display as a solid circle.

3. Press the or buttons to adjust the station run time from Off (-- -- --)

to 1 minute – 8 hours (in 1-minute increments). If seconds format is enabled,

station run time can be set from 01–60 seconds.

NOTE: Hold either button down for rapid advance.

4. Repeat steps 2 and 3 for all stations to be assigned to the selected program.
