Setting Holidays

There are 50 Holiday blocks that can be programmed along with a single schedule for each block. For each block there will be a 
start date and an end date. Within each block one scheduled “on” event and one “off” event can be programmed. Holidays are 
recognized by an H on the display. During the dates chosen, the relays will remain in the “OFF” state and HOLIdy will show on the 
display. 

NOTE:

 During holiday blocks only programmed holiday events will trigger relay operations.

To program holiday blocks follow these guidelines:
1.  Press MODE to advance until the 

SET, DATE and ON@

 icons appear on the display if this selection is not already active. A 

Holiday Number is also displayed on the right side of the display.

2.  The time display will flash - - - - and also show 1H.
3.  Press the + or – buttons to choose the Month that the Holiday will start.
4.  Press ENTER/NEXT and the day of the month, the 1, will flash.
5.  Press the + or – buttons to choose the day that the Holiday will start.
6.  Press ENTER/NEXT and the 

OFF@

 icon is displayed.

7.  The time display will flash - - - - and also show 1H.
8.  Press the + or – buttons to choose the month that the Holiday will end.
9.  Press the ENTER/NEXT and the day of the month, the 1, will flash.
10.  Press the + or – buttons to choose the day that the Holiday will end.
11.  Press ENTER/NEXT and the 

SET   ON@   ON/OFF EVENTS

 icons are displayed. (press ENTER/NEXT twice to skip setting an 

event during the holiday period in which case all circuits will remain off.)

12.  The time display shows - - - - and event number 1 is also displayed on the right side of the display.
13.  Press the + or – buttons to set the time for this holiday event to start.
14.  Press ON/OFF buttons to remove each circuit not affected by this event.  All circuits are initially included with the event. If the 

LOAD

 icon for the circuit is displayed then this circuit will respond to this event.

15.  Press ENTER/NEXT and the OFF@ icon is displayed.
16.  The time display shows - - - - and event number 2 is also displayed on the right side of the display
17.  Press the + or – buttons to set the time for this holiday event to end.
18.  Press ON/OFF buttons to remove each circuit not affected by this event.  All circuits are initially included with the event. If the 

LOAD

 icon for the circuit is displayed then this circuit will respond to this event.

19.  Press ENTER/NEXT and the SET   DATE   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 periods 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. If no holiday events are set, at 12:00 AM on July 4th 
the circuits will be turned to the OFF state. At 12:00 AM on July 5th all circuits will resume normal scheduled operation. If holiday 
events are set to turn on circuits 1 and 2 from 2:00 AM – 6:00 AM then circuits 1 and 2 will turn on between 2:00 AM and 6:00 
AM while circuits 3 and 4 remain off.

Setting Operating Mode – Final Step

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 circuits turn 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 circuits 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) an ON/OFF button will turn OFF the associated 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 circuits when an ON/OFF button is 
pressed.
• 

For MANUAL mode, press the MODE button until the 

MANUAL

 icon appears on the display.
