Frequently Asked Questions - ET2115CP INTERMATIC

How do I install the Intermatic ET2115CP time switch?

Disconnect power at the circuit breaker. Open the enclosure, remove the plastic insulator, and pull out the mechanism. Remove knockouts as needed. Mount the enclosure securely. Connect supply and load wires (copper only, #14-#8 AWG, 105°C min) to the terminal strip, tightening screws to 15.6 lbf-in. Connect ground to the grounding terminal. Replace the insulator and close the door before restoring power.

How do I set the date and time on the ET2115CP?

Press MODE until SET and DATE icons appear. Use + or - to set month, day, and year, pressing ENTER/NEXT after each. For time, press MODE to SET TIME, then set hours/minutes using + or -. Press ENTER/NEXT to set seconds to 00, then MODE to save.

How do I program fixed ON and OFF events?

Press MODE until SET FIXED ON/OFF EVENTS appears. For each event, use + or - to set the time. Press ENTER/NEXT to save. Odd-numbered events are ON, even-numbered are OFF. Up to 48 ON and 48 OFF events can be programmed.

How do I enable or disable Daylight Saving Time (DST)?

Press MODE until SET and DST icons appear. Press + for ON or - for OFF, then ENTER/NEXT. If enabled, choose a DST rule: US2007, MX1986, or CUSTOM (set start/end month and week). Press MODE to save.

Press ENTER/NEXT and the OFF@ icon is displayed. 15. The time display shows - - - - and event number 2 is also displayed on the right side of the display. 16. Press the + or - buttons to set the time for this holiday event to end. 17. Press ENTER/NEXT and the SET, DATE and ON@ icons appear on the display. The next holiday number is displayed on the right side of the display.

If Then
Another holiday period needs to be set	Return to step 2.
All the events are set Press MODE to save and exit. The procedure is complete.

Example: July 4th would have a start date of Jul 4 and an end date of Jul 5. At 12:00 AM on July 4th the circuit will be turned to the OFF state. At 12:00 AM on July 5th the circuit will reconcile and will be turned to the correct state of operation.

Setting Operating Mode

The time switch can be set to one of three operating modes: AUTO (default setting), ENERGY SAVER or MANUAL. Once operating mode is selected the time switch setup is complete. NOTE: If no scheduled events are programmed, only MANUAL mode is available. In AUTO mode, the time switch follows the user-programmed events and the circuit turns ON and OFF at the programmed time(s). • To place in AUTO mode, press MODE and advance until the AUTO icon appears on the display. - In AUTO mode, pressing an ON/OFF button temporarily overrides the current state of the circuit. The time switch returns to the normal schedule at the next programmed event. In ENERGY SAVER mode the time switch operates similarly to AUTO mode with the following exceptions: \- The ON/OFF buttons manually activate the circuit for only a 2-hour period. \- When a 2-hour period is active, pressing ON/OFF extends the active period by 2 hours. \- Pressing and holding (for 3 seconds) the ON/OFF button will turn OFF the circuit. \- The ON/OFF buttons manually activate the circuit for only a 2-hour period. - When a 2-hour period is active, pressing ON/OFF extends the active period by 2 hours. - Pressing and holding (for 3 seconds) the ON/OFF button will turn OFF the circuit. For ENERGY SAVER mode, press the MODE button until the AUTO icon on the display flashes. In MANUAL mode the time switch does not follow any programmed events and only activates the circuit when the ON/OFF button is pressed. \- For MANUAL mode, press the MODE button until the MANUAL icon appears on the display.

Deleting (Clearing) an Event

Fixed events can be deleted from the time switch. If you need to delete an event, follow this procedure. 1. If necessary, press MODE to scroll through the different mode selections until SET FIXED ON/OFF EVENTS appear on the display. 2. Press ENTER/NEXT as necessary to scroll through the scheduled events until you see the event you want to delete. 3. Press + and - at the same time until the display shows --:-- --. This indicates the event is erased. 4. If necessary, press ENTER/NEXT to scroll through the other configured events. 5. Press MODE to save the changes and exit.

Clearing Time Switch Memory

During a “Clear Time Switch Memory” operation, the time switch resets all programmed settings to their factory default value. The following occurs: - After a brief period of time the time switch model number appears, followed by the USB Boot Loader version, EE Boot Loader version, the firmware revision and finally the Reset Reason Code. - MEMCLR is displayed followed by DONE when the operation is completed. To perform a "Clear Time Switch Memory" operation do the following: 1. Press and hold ENTER/NEXT. 2. While pressing and holding ENTER/NEXT, press and release the RESET (round) button. Do not release ENTER/NEXT. 3. Continue to press and hold ENTER/NEXT until MEM CLEAR then DONE briefly appears.

Writing Time Switch Program Data to a USB Memory Stick

The time switch has the capability to copy its programmed data (event schedules, holidays, output configuration, DST on/off setting, DST rule setting and geographical location) to a USB memory stick. Follow these steps to transfer all programming from the time switch to a USB memory stick: 1. Press MODE to advance until wr USb is displayed. 2. Press ENTER and insUSb is displayed. 3. Insert a USB memory stick into the USB port on the front face of the time switch. 4. SCHEdL 01 is displayed. Press + or - to increment/decrement the schedule number on the display (01-99). 5. When the desired number is displayed, press ENTER and this will write the data file to the USB memory stick. The file name will be SCHEDLx x.T XT where xx is the schedule number selected in the previous step. 6. After the file is written REMOVE is shown on the display. 7. Remove the USB memory stick and the time switch will advance to the next mode selection. If all procedures are completed, press MODE repeatedly until back to the operating mode selection (AUTO, ENERGY SAVER, MANUAL).

Reading Time Switch Program Data from a USB Memory Stick

The time switch has the capability to read program data (event schedules, holidays, output configuration, DST on/off setting, DST rule setting and geographical location) from a USB memory stick. Follow these steps to transfer all programming from a USB memory stick to the time switch: 1. Press MODE to advance until rd USb is displayed. 2. Insert a USB memory stick containing the desired data file into the USB port on the front face of the time switch. 3. Press ENTER and insUSb is briefly displayed. 4. SCHEdL.xx is displayed where xx is the first data file number found on the USB memory stick. 5. Press + or - to scroll through the data files on the USB memory stick (if more than one file is stored on this stick). 6. When the desired number is displayed, press ENTER and the time switch will read the data file from the USB memory stick. 7. After the file is read into the time switch, DONE is briefly shown on the display followed by REMOVE. 8. Remove the USB memory stick and the time switch will advance to the next mode selection. If all procedures are completed, press MODE repeatedly until back to the operating mode selection (AUTO, ENERGY SAVER, MANUAL).
