Timer Installation

Note: The ECXTRA indoor timer is not weather resistant and must be installed indoors or in a protected area.

Indoor Model Installation

1. Select a location for the timer within 4′ (1,2m) of an electrical outlet to enable the transformer cord to easily reach. Make sure the outlet is not controlled by a light switch or used to power any large appliance such as a refrigerator, freezer, or air conditioner.

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

3. Place the mounting bracket (A) against the wall aligning the top edge at about eye level. Drive two stainless steel screws (B) into the wall through two holes provided in the bracket. For additional stability, secure the bracket with three screws.

Note

: If you are installing the bracket on drywall or masonry, install screw anchors (C) to prevent screws from loosening.

Optional - Insert 3/4″ (19mm) PVC conduit (D) for valve wiring into bracket sleeve (E).

5. Align the slotted openings on the back of timer hous

ing with the mounting bracket tabs. Slide the timer downward to engage the tabs.

Note: After installation, store the Quick Start Guide in

the pocket (F) formed between the timer and bracket.

Connecting the Valves

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

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

gauge (2mm2–1mm2) 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.

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: Use Toro Waterproof Wire Connectors (Model # 53687) or grease caps on all exposed wire splice connections to prevent corrosion, connection failure and possible 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″ (9mm) from all wires being used.

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.

Referring to “Timer Components” on page 5 and the diagram above, connect 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 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.

Connecting a Pump Start Relay

CAUTION: To prevent timer damage, ensure the

24 VAC pump relay current draw does not exceed

0.30 Amps. Do not connect the timer directly to the pump starter.

1. Route a wire pair from the pump relay into the timer housing.

2. Connect one wire to the terminal labeled COM (10). Connect the remaining wire to the terminal labeled PUMP/MV (9) as shown below.

CAUTION: To prevent pump damage due to back pressure, connect a jumper wire from any unused zone terminal to a zone terminal with a valve connected.

Note: Refer to “Pump Control” section on page 29 for

important pump control information.

Connecting the Plug-In Transformer

CAUTION: Do not plug the transformer into an electrical outlet until all of the wiring procedures have been completed.

Route the cord from the transformer (13) through the small opening provided in the base of the housing as shown below.

2. Connect one transformer cable wire to each terminal

labeled 24 VAC (8). The wires can be connected to either terminal.

Note: When power is applied to the timer, the display will begin flashing 12:00 am. Press any button to halt flashing.

Outdoor Model Installation

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

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

3. Three lower mounting holes (C) are provided. The center hole is open and the outer holes are plugged. If you intend to use the outer holes for installation, carefully drill through the plugs with a 3/16″ (6mm) drill bit.

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

(D) - 1/2

″ (13mm) for power and equipment ground

wires.

(E) - 1/2

″ (13mm) for optional Toro RainSensor wires.

(F) - 3/4

″ (19mm) for sprinkler valve wires.

4. If planning to install the optional Toro RainSensor, remove hole plug.

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 wood screw (provided) into the wall at eye level (A). Leave the screw extended approximately 1/4″ from the wall.

Note

: If you are installing the timer on drywall or masonry, install screw anchors to prevent screws from loosening. Use the dimension shown to predrill holes for screw anchors.

3. Hang the cabinet on the screw using the keyhole slot (B) 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 local electrical codes.

5. Install 1/2

″ conduit (C) for power/equipment ground

wires and 3/4″ conduit (D) for valve wires.

Note: After installation, store the Quick Start Guide

on the hook located on the inside of the door.
