Indoor Timer Installation

IMPORTANT: The ECXTRA Indoor model is not weather resistant and must be installed in a sheltered area.

1.Select a location for the timer within 4′ (1.2m) . of an electrical outlet. Make sure the outlet is . not controlled by a light switch.

2.Remove the mounting bracket from the back of the timer housing by pulling the lower edge of the bracket away and down from the timer housing.

3.Place the mounting bracket against the wall, aligning the top edge at about eye level. Secure the bracket using the two stainless steel screws provided, or use appropriate screw anchors if installing on drywall or masonry.

Note: If optional valve wiring conduit is preferred, insert 3/4″ (19mm) PVC conduit into the sleeve provided on the bottom edge of the bracket.

4.Align the slotted openings on the back of timer housing with the mounting bracket tabs. Slide the timer downward to engage the tabs.

Note: Store the Quick Start guide in the pocket formed between the timer and mounting bracket.

Connecting the Valves

1.Route the valve control wires between the valves and the timer.

Note: The snap-in wire connectors accept 14 to 18 gauge wire. Using 18-gauge, multi-strand, direct-burial irrigation 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: Use Toro waterproof wire connectors (Model # 53687) or grease caps on all exposed wire connections to prevent corrosion, connection failure and short circuit.

4.Route the wire cable into the timer through the large opening in the base of the housing or through PVC conduit (if installed). Strip insulation back 3/8″ (10mm) from all cable wires.

Note: The zone modules have quick-release wire terminals. To attach wires, simply raise the lever, insert the stripped wire, and press the lever down to secure.

5.Secure the valve common wire to the terminal labeled COM. Connect the individual zone valve wires to the appropriate zone module terminals. Connect the master valve wire (if applicable) to the terminal labeled PUMP/MV.

Connecting a Pump Start Relay

Note: Connecting a master valve or pump start relay is optional and may not be required for your sprinkler system.

Caution: To prevent timer damage, do not connect the timer directly to the pump starter. A 24 VAC, 0.3A (max) relay must be used.

1.Route wire pair from the 24V relay into the timer.

2.Connect one wire to the terminal labeled COM. Connect the remaining wire to the terminal labeled PUMP/MV.

CAUTION: To prevent pump damage due to back pressure, remove all unused zone modules. Connect a jumper wire from an unused zone

terminal to a terminal with a valve connected.

Connecting the Plug-in Transformer

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 through the small opening in the base of the housing.

2.Connect one cable wire (in either order) to each terminal labeled 24 VAC.

Note: The display will begin flashing 12:00 am. Press any button to halt flashing.

Outdoor Timer Installation

Preparing the Timer Cabinet

1.Remove the lower housing cover by pulling outward on the handle.

2.Remove two phillips screws from the transformer access cover. Pull the cover outward from the bottom to remove.

Note: Three lower mounting holes are provided. The center hole is open and the outer holes partially-through pilot holes. If the outer holes are to be used, open the pilot holes using a 3/16″ (6mm) drill bit.

Three wiring (conduit) access holes are provided in the cabinet base as follows:

1 – 1/2″ (13mm) for input power wires.

1 – 3/4″ (19mm) for sprinkler valve wires.

1 – 1/2″ (13mm) for Toro RainSensor (optional). Note: Leave access holes plugged if not used.

Installing the Cabinet

1.For safe, reliable operation, select an installation site which will provide the following conditions:

•Protection from irrigation spray, exposure to direct sun during the hottest hours, wind and snow.

•Access to a grounded power source which is not controlled by a light switch or utilized by a high current load appliance, such as a refrigerator or air conditioner.

•Access to the sprinkler control valve wiring and optional accessory wiring.

2.Drive a provided stainless steel screw into the wall at eye level. Leave a 1/4″ (6.4mm) gap between the screw head and the wall.

Note: Use appropriate screw anchors if installing the timer on drywall or masonry.

3.Hang the cabinet on the screw using the keyhole . slot on the back panel. Make sure the cabinet slides down securely on the screw.

4.Install the lower mounting screw(s) and tighten securely.

Note: Conduit and adapters are not provided. Install conduit as required by electrical code.

5.Install 1/2″ (13mm) conduit for input power wires and 3/4″ (19mm) conduit for valve wires.

Note: After installation, store the Quick Start guide on the inside of the cabinet door.

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 to 18 gauge (1mm2) wire. Using direct-burial

irrigation cable is recommended. Choose a cable that has at least one additional 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 this information when connecting the valve wires to the timer.

CAUTION: To prevent corrosion, connection failure 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 installed). Strip insulation back 3/8″ (10mm) from all cable wires.

Note: The zone modules have snap-in wire terminals. To attach wires, simply raise the lever, insert the stripped wire, and press the lever down to secure.
