Cabinet Installation; Field Wire Connections - Toro TMC-424E User Manual

Cabinet Installation

1. Drive a wood screw into the wall within eye
level until only 1/4" (10mm) of the screw is
exposed.
NOTE: If installing the controller on drywall or
masonry, install the appropriate type screw
anchors.
2. Hang the cabinet on the screw using the
keyhole slot.
3. Open the controller cabinet and swing open
the timing mechanism to access the lower
mounting screw location.
4. Install the lower mounting screw in the hole
provided and tighten securely.
5. Fill out the provided Watering Schedule form with program and system details. Affix the provided
hook and loop disks to the form in the designated locations. Attach the form to the inside of the
cabinet cover.

Field Wire Connections

NOTE: Using 14–18 AWG (2–1mm
field wire connections is recommended. This cable is made specifically for underground installa-
tion and is available in various lengths and conductor count. Select a cable that has at least one
conductor for each valve connection and one conductor to provide a valve common connection.
1. Route the valve control wires between the valves and the controller.
2. Attach the white wire to either lead from each valve solenoid to provide a valve common wire.
3. Attach a separate wire to the remaining valve solenoid lead of each valve.
NOTE: For reference when making wire connections at the controller, note of the wire color
used for each control valve connection and the corresponding watering zones.
4. Secure all wire splices using water-proof wire connectors or any appropriate method of
protecting wire splices from direct contact with soil or moisture.
5. Route the cable into the controller through one of the 3/4" (19mm) access holes in the base
of the housing or through the PVC conduit (if installed). Strip insulation back 3/8" (10mm) for
wiring terminal connections.
6. Secure the field common wire(s) to common terminal(s) (C).
7. Secure the individual valve wires to the appropriate expansion module station output terminals
8. Connect one wire from the master valve or pump start relay to terminal (P).
