Setup & Operation Instructions Simple To Set Timer (SST)

Installation

Tools and Supplies Needed

• Phillips screwdriver
• Wire stripper
• Hammer
• Valve wire: direct burial, color coded multi-strand (not included)
  • 18 gauge for runs less than 800 feet.
  • 14 gauge for runs greater than 800 feet.
• Watertight splice connectors (not included)

Step 1. Mount Timer

Mount the SST in an accessible location

NOTE: SST indoor timers are for indoor use only. SST outdoor timers can be used indoors or outdoors.

1. For indoor installation, choose a location within 5 feet of an AC power outlet and at least 15 feet away from major appliances or air conditioners.
2. Drive a screw into the wall, leaving an 1/8" gap between the screw-head and the wall (use the supplied wall anchors if necessary).
3. Locate the keyhole slot on back of the unit and hang it securely on the screw.
4. Remove the wiring bay cover at the bottom of the unit and drive a screw through the center hole as shown (use the supplied wall anchors if necessary).

Step 2. Connect Power

WARNING: DO NOT plug in or apply power to the timer until you have completed and checked all wiring connections.

Indoor Timer

Attach the transformer connector to the 24VAC POWER pin connection on the terminal strip.

WARNING: Do not attempt to link two or more timers together using a single transformer.

Outdoor Timer

Standard Installation: The SST outdoor version comes with a power cord and 24VAC transformer already connected.

Hard-wire Installation: Disconnect or shut off the external power source before connecting or disconnecting wires to the timer.

1. Remove the wiring bay cover at the bottom of the unit.
2. Locate the wiring compartment in the lower left-hand corner of the unit and using a screwdriver, unscrew wiring compartment front cover.
   
3. Unscrew the wire-nuts from the three wires connecting the power cord to the timer.
4. Remove the metal bracket holding the power cord to the back of the wiring compartment and pull the cord out through the bottom of the cabinet.
5. Route the three wires from an external power source into the wiring compartment.
6. Using the wire-nuts, connect the external power wires to the internal connection wires inside the wiring compartment.
   WARNING: Be sure to connect the color coded external wires to the same color internal connection wires, as follow:
   Black wire (power)
   White wire (neutral)
   Green wire (ground)
7. Verify that all wiring connections are secure, then replace the wiring compartment cover.

Step 3. Connect Valve Wires To Timer

Valve Connections

1. Use direct burial cable to run wiring from the timer to valves in the field.
2. Connect a color coded wire from the direct burial cable to either wire on the valve.
3. Connect the remaining wire on each valve to a “common" wire which then connects to the timer.

NOTE: Use water-tight connectors for all wire splice connections. Depending on your landscape setup, you may need to run extension wires for the power and common connections.

Timer Connections

1. Use a wire stripper to strip away approximately 1/4" of insulation from the end of the valve wire.
2. Push the exposed end of the color coded wire from each external valve (or zone) into the corresponding zone number on the terminal block.
   NOTE: To insert or remove a wire, use a screwdriver to press down on the connection release.
   
   WARNING: To prevent damage to the timer, connect only ONE valve to each open zone slot on the terminal block.
3. Connect the common wire to one of the COMMON slots on the terminal block.
4. Check that all wiring connections are secure.
   NOTE: Do not remove the yellow jumper wire on the terminals marked RAIN SENSOR unless you're connecting an optional rain sensor. See "Rain Sensor" on page 3 for more information.
   

Step 4. Verify System Operation

Battery Pull Tab

• To activate the internal battery, grasp the yellow pull-tab on the side of the timer and pull it out.

NOTE: If the timer doesn't have AC power for more than a week, the time needs to be reset. This conserves battery power for future outages. Program details are kept in long term non volatile memory so they are not lost even after long power outages.

Apply Power

Indoor Model

• Plug the transformer into a wall outlet.

Outdoor Model

• Turn on main power supply or plug the power cord into a waterproof receptacle.

NOTE: Do not plug the timer into a socket that is controlled by a secondary ON/OFF light switch or GFI outlet.

Test Watering

1. Turn the dial to the ZONE 1 position. --> Press the WATER 1 ZONE NOW button. The zone will start watering for the default run time of 10 minutes and the green LED corresponding to WATER 1 ZONE NOW button turns on.
2. To stop watering before time is up, press the WATER 1 ZONE NOW button a second time. The green LED corresponding with the WATER 1 ZONE NOW button will turn off.
3. Repeat the above steps until all connected zones have been tested.
4. Replace the wiring bay cover on front of the unit.

Optional Accessories

Rain Sensor

Connect an optional Rain Sensor to the Timer

1. Remove the wiring bay cover at the bottom of the unit.
2. Remove the yellow jumper wire from the terminals marked RAIN SENSOR on the terminal block.
   
   NOTE: Do not remove the jumper wire unless connecting a rain sensor. The timer will not function if the jumper wire is removed and a rain sensor is not connected.
3. Connect the two wires from the sensor to the RAIN SENSOR terminals.
   

Master Valve Or Pump Start Relay

Connect an optional master valve or pump start relay

SST timers support the use of a master valve or pump start relay. A pump start relay connects to the timer the same way as a master valve, but connects differently at the water source.

1. Using a direct burial cable, connect one of the wires from the master valve (or pump start relay) to the timer terminal marked MSTR VALVE.
2. Using a direct burial cable, connect the remaining wire from the master valve (or pump start relay) to one of the timer terminals marked COMMON.

Additional instructions for connecting a pump start relay

• To avoid possible pump damage, connect a short jumper wire from any unused zone terminal(s) to the previous terminal, continuing back to the nearest zone terminal in use (as shown below).
  For example, if a 4 zone model timer is in use with only two zones connected, route the terminals for zones 3 and 4 to the nearest active terminal (zone 2 in the example below).

WARNING: Make sure that the total draw of the master valve (and/or pump start relay) plus the draw of the valve does not exceed 650mA at 24VAC,60hz. Note that the timer does NOT provide main power for a pump.
