Getting Started - Toro TMC-424 Manual Del Usario

Getting Started

The unique design of TMC-424 Series takes "modularity" to the next level.
The modular components of this series controller are:
• Color-coded 4-and 8- station Expansion Modules for easy identification of
model options.
• Modular internal power supply to adapt to your customer or site job needs.
• Modular timing mechanism is easily removed from the cabinet for remote
"Armchair Programming."
Armchair Programming enables you to remove the timing module from the
cabinet after AC power has been initially applied and modules recognized.
With the control knob in the OFF position, swing the module out and connect
a 9V battery. Simply unplug the ribbon cable and push down on the top mod-
ule hinge to release. Now, you can program the controller, review your water-
ing schedules and have the system ready to run automatically upon
completion of the installation.
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-424 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 of segmenting specific site conditions, such
as north-facing slopes or shaded areas. As you can see, the availability of four pro-
grams allows you to have unique watering programs for your varied landscape
needs. Watering programs can be operated in sequence or simultaneously 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-424 provides up to 16 watering cycle start time slots that can be
allocated to programs A, B, C and D in any combination. For example, Program A
could have 10 start times; Program B four start times; Program C two start times
and Program D no 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.
