through this manual and familiarize yourself with the
TMC-212 components, installation requirements and
operating features.
The User’s Guide is divided into six main sections
• The first section provides a brief description of
the controller components and display elements.
•The second section takes you step-by-step through
the installation process.
• The next section provides fundamental irrigation
system operation, basic controller operation as well
as specific programming and operating characteristics
of the TMC-212.
• The fourth section takes you step by step through the
programming process.

• An appendix provides various reference information,
specifications and warranty information.
A watering schedule form (affixed to the cover of the
outdoor model cabinet and included on page 20 of the
User’s Guide for the indoor model) provides a convenient
place to record the location of each watering station area
and specific details of your automatic watering programs.

CAUTION: TMC-212 indoor controller models are
not weather resistant and must be installed indoors
or in a protected location.
1. Select a location for the controller within 4' (1.2m) of
an electrical outlet to enable the transformer wires to
easily reach. Make sure the outlet is not controlled by
a light switch.
2. Remove the mounting bracket attached to the back
of the controller housing by pulling the lower edge of
the bracket away and downward from the controller
housing.
3. Place the mounting bracket (A) against the wall
aligning the top edge at about eye level. Drive three
1" (25mm) wood screws (B) into the wall through the
three holes provided in the bracket.
Note If you are installing the bracket on drywall or
masonry, install screw anchors (C) to prevent screws
from loosening.
4. Optional - Insert 3/4" (19mm) PVC conduit (D) for
valve wiring into bracket sleeve (E).
5. Align the slotted openings on the back of controller
housing with the mounting bracket tabs. Slide the
controller downward to engage the tabs.
Note: After installation, store the Quick Reference
Guide and the Watering Schedule Form in the
pocket (F) behind the controller.

1. Route the valve control wires between the valves and
the controller.
Note: The station modules and wire connectors accept
14–18 AWG (2.5–1.0mm2).solid-core copper wire.
Sprinkler system connection cable is recommended.
2. Attach the white-color cable wire to one wire from
each valve solenoid. (Either solenoid wire can be
used for this connection.) This is called the valve
common wire.
3. Attach a separate cable wire to the remaining wire
from each valve solenoid. Make a note of the wire
color code used for each valve and the watering sta-
tion it controls. You will need to have this information
when connecting the valve wires to the controller.
4. Secure all wire splices using twist-on wire connectors.
To prevent corrosion and possible short circuits, use
a grease cap or similar waterproofing method to insu-
late each connection.
5. Route the wire cable into the controller through the
large opening in the base of the housing or through
PVC conduit if it is installed. Strip insulation back
1/2" (13mm) from all cable wires.
Note: The station module has snap-in wire connectors
To attach wires, simply raise the lever and insert the
bare wire end into the small hole beneath the lever.
Press the lever down to secure the wire. Pull lightly on
the wire to confirm that it is locked into the module.
6. Referring to the Controller Components on page 5 and
the diagram above, secure the valve common wire to
the terminal labeled COM (8). Connect the individual
station valve wires to the appropriate station module
terminals (11). Connect the master valve wire (if
applicable) to the terminal labeled PUMP/MV (9).
Note: Connecting a master valve or pump start relay
is optional and may not be required in your sprinkler
system.

CAUTION: Never connect an auxiliary pump
starter directly to the controller. A 24 VAC relay,
rated at 0.30A maximum current draw, must be used
to connect the controller to the pump starter circuit.
1. Route a wire pair from the pump start relay into the
controller housing.
2. Connect one wire to the valve common COM (8).
Connect the remaining wire to the PUMP/MV (9) as
shown below.
CAUTION: If the pump does not have an auto-
matic pressure control switch, prevent pump damage
due to “dead-heading,”by connecting a jumper wire
from any unused station terminal to a station terminal
with a valve wire connected.
Note: Refer to “Pump Control and Well Recovery” section
on page 28 for important pump circuit control information.
CAUTION: Do not plug the transformer into an
electrical outlet until all of the wiring procedures have
been completed.
1. Route the cable from the transformer (13) through the
small opening provided in the base of the housing.
Wrap the cable around and through the restraining post
as shown below.
2. Connect one transformer cable wire to each terminal
labeled 24 VAC (10). The wires can be connected to
either terminal.
Note: The display will begin flashing 12 00 a.m. Press
any button to stop the display from flashing.
