    Daily Event and uses only one of the 16 available events. See Repeat Programming on the next page. Momentary Option Any EC72 Series model can be converted to momentary output. This decision should be made prior to programming. See pages 22-23 for more information.
  • Page 21 Repeat Programming Repeat Programming simplifies programming and increases the total number of events through daily repetition of certain ONs and OFFs. For example, say that a certain event will occur at the same time every day — e.g., 8:00 AM ON. Rather than programming 8:00 AM ON Monday, 8:00 AM ON Tuesday, 8:00 AM ON Wednesday, etc., the Daily Key can be used, causing the event to be repeated each and every day of the week and using only one of the 16 available events.
  • Page 22 The Momentary Option provides a two-second momentary contact closure that is ideal for ringing school bells and church chimes or utiliz- ing latching relays. Any EC72 Series model can be converted to momentary output by clipping a jumper wire, which causes all events to become ON events of two-second duration.
  • Page 23 Figure 9A. EC72 Jumper Wire To convert the EC72D: 1. Remove the control according to directions on page 17. 2. The jumper wire, J29, is located on the back side of the control in the upper left-hand corner of the board. See Figure 10 below. Clip J29.
