Toro EC-XTRA Landscape Timer, 6-Zone (53794) Installation Guide

Connecting the Valves

1. Route the valve wires or wire cable from the valves,

into the timer cabinet.

Note: The snap-in wire connectors accept 14–18

gauge (2mm

to 1mm

) wire. Using direct-burial irriga-

tion cable is recommended. Choose a cable that has

at least one more wire conductor than the number of

valves to be connected.

2. Attach the white color-coded wire to either one of

the wires from each valve solenoid. This is called the

valve common

wire.

3. Attach an individual color-coded wire to the remaining

wire from each valve solenoid. Make a note of the wire

color used for each valve and the watering zone it

controls. You will need to have this information when

connecting the valve wires to the timer.

CAUTION: To prevent corrosion, connection fail-

ure and possible short circuit, use Toro waterproof
wire connectors (Model # 53687) or grease caps on all
exposed wire splice connections.

4. Route the wire cable into the timer through the large

opening in the base of the housing or through PVC

conduit (if it is installed). Strip insulation back 3/8″

(10mm) from all cable wires.

Note: The zone module has snap-in wire terminals.

To attach wires, simply raise the lever, insert the

stripped wire, and press the lever down to secure.

5. Referring to the Timer Components on page 5 and

the diagram above, secure the valve common wire to

the terminal labeled COM (10). Connect the individual

zone valve wires to the appropriate zone module

terminals (11). Connect the master valve wire (if appli-

cable) 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.
