Intermatic ST01 Series Self-Adjusting Wall Switch Timer Installation and User Instructions

Troubleshooting Guide

Observed Problem

Switch timer does not switch ON/OFF but display looks normal.

Switch timer won’t enter AUTO or

RANDom mode when you press MODE.

Possible Cause

Switch timer is not set in AUTO, RANDom, or

MANual mode.

The time of day or timer settings have not been set.

Programmed schedule(s) are incorrect.

What to Do

Press MODE to select the operational mode you want to use.

Make sure the time of day and at least one scheduled activity have been set.

Press ON/OFF to review the settings and revise them as necessary. See instructions at the left.

Switch timer switches at incorrect times or skips some of the programmed times.

Switch timer is in RANDom mode, which varies switching times up to ±20 minutes (to give your home a “lived-in” look).

The Astronomic and Specific switching times are in conflict. For example, you’ve set ON to

DUSK and OFF at 8 pm, and due to seasonal changes, DUSK has advanced to 8:30 pm.

NOTE: Your switch timer automatically skips any conflicting ON event as summer approaches to prevent unwanted operation of lights or other controlled devices. See “What to Do” if you want to identify and remove conflicting settings.

If you don’t want to keep the switch timer in

RANDom mode, press MODE to change to AUTO mode.

4.

Complete the steps for setting the Time and

Date, then temporarily change the date to

June 21st.

Review the DAWN and DUSK settings by pushing the ON/OFF button.

Make sure the specific ON or OFF time settings won’t interfere with these DAWN and

DUSK times. Make changes as necessary.

When finished, change the Date setting back to today’s date.

The lights or controlled devices don’t match the programmed ON/OFF status immediately after setting the time or programming a schedule.

Load only operates when the remote

(3-way) switch is in one position, or the switch timer ignores the remote switch.

The switch timer ignores a 3-way remote switch even though it is wired correctly.

The load turns off immediately after being turned on.

The battery tray is difficult to replace.

Switch timer does not “catch up” automatically to the programmed load state. The status of the switch timer will remain as is until it comes to the next programmed ON/OFF time.

The remote switch is wired incorrectly.

•

•

•

There is an excessive length of wire (more than 100 feet), or there is buried wire to the switch.

•

•

•

•

The remote switch is not functioning properly or worn out.

The remote switch or switch timer is wired wrong.

There is an excessive length of wire

(greater than 100 feet)

There is buried wire to the remote switch.

The switch timer is not functioning properly.

Battery is not seated in the tray.

The tray is misaligned.

The contact tabs of the tray are bent.

After entering your schedules or the time, then returning to the AUTO mode, push the ON/OFF button to change the load state if necessary.

Recheck the wiring, especially for the jumper, according to “If a 3-way Switch Timer” and “If a

Multiple Switch Timer Setup.”

Eliminate the condition: either replace the buried cable, do without the remote switch, or contact

Intermatic Customer Service for more options.

Replace the remote switch.

If the problem persists with the switch timer’s red wire disconnected or with a remote switch temporarily connected right at the switch timer, replace the non-functioning switch timer. Otherwise, try the above suggestions.

Seat the battery in the tray, then reinstall.

The switch timer operation is sluggish or not switching ON/OFF at all.

Though the “BATT” message is not being displayed, the battery is getting weak.

Replace the battery. To test the battery, press the

ON/OFF button. The timer should “click.”

Timer shows ON but the light or other controlled device is OFF.

The light or controlled device itself may be switched OFF.

2 – Install the Switch Timer

1.

Turn off power at the service panel by REMOVING FUSE or

TURNING THE CIRCUIT BREAKER OFF.

7/16”

Remove the existing wall switch.

Trim building wires to 7/16” as shown.

g.

h.

NOTE: If the building’s wiring colors don’t allow you to tell wire “A” from “B,” just pick one of the two wires and connect as if it is wire “B.” After the installation is complete, if the controlled light or device will not turn on properly, simply reverse wires “A” and “B.” See Steps J and K for how to check.

Tuck wires into the timer wall box leaving room for the timer.

Using screws provided, mount the switch timer into the wall box, then install the wall plate.

If a Single Switch Setup:

BLACK WIRE

Connect one of the two wires from the wall to the black wire from the switch timer, using the twist connectors provided. i.

j.

Install the remote 3-way switch in its box and install wall plate. Turn the power back on at the service panel.

Connect the other wire from the wall to the blue wire from the switch timer, using the twist connectors provided.

BLUE WIRE

RED WIRE

(capped, not connected)

NOTE: The RED wire is not used in single-switch installations.

Cap with a twist connector.

Make sure the switch timer displays “MAN” mode. Do the following test with the remote switch in each of its 2 positions:

Press the ON/OFF button on the switch timer several times.

Each time that you push the ON/OFF button, the switch timer should “click” and the controlled light or device (the “load”) should turn on or off. If so, proceed to Step K.

-

If the timer clicks but the load does not operate, re-check your wiring and make sure the load is functional.

-

If the timer clicks but the load only operates when the remote switch is in one of its 2 positions, you need to turn off the power at the service panel, then reverse wires “A” and

“B.” You can reverse wires “A” and “B” at the remote switch wall box, or you can reverse wires “A” and “B” where they connect to the red and blue wires of the switch timer. Then turn power back on at the service panel and repeat Step J. k.

Verify that the controlled load turns on or off each time that the remote switch is operated. Your timer is now ready to be set.

If a Multiple Switch Timer Setup:

Multi-switch applications using the ST01 Series switch timer are wired differently than when using conventional toggle switches.

Read the following installation instructions carefully.

•

Multiple switch timers may be mounted in an unlimited number of adjacent junction box slots.

•

No derating is required for multiple switch timers.

3 – Intro to Programming: Read Before You Begin

As you use the menus to program, it will be helpful to have an overview of how they are organized. Press the MODE button to rotate through the switch timer’s modes: SET UP, PROGRAM,

AUTO, RANDOM, and MANUAL. All menus “loop”, so they repeat when you get to the end. AUTO and RANDOM modes are skipped until there is at least one ON/OFF setting.

Once you reach a Mode you want to work with, press the ON/

OFF button to rotate through the loop of settings available for that Mode, returning to the beginning. For example, in SET UP mode, you will see HOUR, MINute, AM/PM, Year, MONth, etc.

Use the + or – buttons to change a setting when it is FLASH-

ING (e.g., the correct hour). Holding the button makes the numbers scroll faster. Pressing ON/OFF again advances to the next setting and automatically saves — whether you changed the setting or not. Saving is automatic, there’s no extra step.

If you’re interrupted during programming, your work to that point is automatically saved after 5 minutes.

Press MODE when you’re finished to navigate to the mode you want to operate the switch timer: Auto, Manual, or Random.

4 – Clear Any Existing Programming

It’s unlikely that the new switch timer has any existing programming but to make sure, use this procedure before setting the time.

2.

Open the front cover.

Hold down ON/OFF.

3.

Using a pen or paper clip, press and release RESET, which is the small round button to the lower right of the + button.

4.

When the screen displays INIT, release ON/OFF. The screen will initialize, then flash “12:00 am” in MANual mode.

All previous settings are now deleted.

5 – Set the Date and Time

In order for the Astronomic Feature and automatic Daylight Saving Time settings to function properly, the CALENDAR settings must be entered correctly.

About the Battery

The single lithium CR2 battery operates the ON/OFF function

(“click-click”) and maintains time of day and date. The screen flashes “BATT” when the battery is getting low.

The battery may be changed without removing AC power.

You have about one minute to swap batteries before the switch timer “forgets” the date and time settings. Afterwards, if the display is wrong or flashes “12:00 AM”, reset the time and date. All other settings (your ON/OFF programming) remain in memory indefinitely without battery or AC power.

To test the battery, press the ON/OFF button. The timer should

“click.”

Replace the battery per Section 1 Instructions as soon as possible after the low “BATT” message appears.

Do not leave exhausted battery in Switch Timer. (Risk of leakage.)

Replace only with Panasonic Type CR2 lithium battery or equivalent CR2 battery approved by Underwriters Laboratories (UL).

Dispose of the used battery promptly according to local regulations. Keep battery away from children. Do not disassemble and do not dispose of battery in fire.
