Toro TEMPUS Controller

Connecting the Valves

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

Note: Residential sprinkler wire is recommended.

2. Attach the red color-coded wire from each valve solenoid (either solenoid wire

can be used for connection) to a single cable wire. This is called the “valve

common” wire. See Figure 2.

3. Attach a separate cable wire to the remaining wire from each valve solenoid.

Note the wire color code used for each valve and the watering station it controls.

You will need to have this information when connecting the valve wires to the

controller.

4. Secure all wire splices using wire nut connectors. To prevent corrosion and

possible short circuits, always use an insulated wire nut, grease cap or similar

waterprooﬁng method.

5. At the controller end of the valve connection cable, strip back 0.25 in. of insulation

from all cable wires.

6. Secure the valve common wire to the terminal labeled COM. Connect the individual

valve wires to the appropriate station terminals. Connect the master valve wire (if

applicable) to the terminal labeled MV.

Note: Connecting a master valve or pump start relay is optional and may not be

required for your sprinkler system.
