How can I count the number of switchings memorised on IHP time switches.

IHP time switches can be used to program two types of switching: ON or OFF:

  • One switching takes up one memory space.
  • One range (ON/OFF) takes up two memory spaces
  • The number of memory spaces is limited and depends on the type of time switch

If you are creating several identical operating ranges at the same times over several days, it is preferable to use the "repeat" function.
This "repeated" range will only take up two memory spaces, increasing the number of possible switchings.

Note:   Some IHP's can generate pulses (between 1 and 59 s). These take up two memory spaces.
