Operation in general
The timer starts with the pre-time. During the pre-time, the duration of the main-time will blink in the
display. The duration of the main-time can be limited during the pre-time by activating the Stop timer
button. The pre-time is programmable from 0 up to 255 minutes. The pre-time can be skipped by means
of the quick start function by activating the Start / Pause button. The main-time will follow automatically
after the pre-time. During the main-time the remaining time will appear on the display. The main-time is
programmable from 0 up to 2550 minutes.
The main-time can temporarily be interrupted by activating the Start / Pause button. The post-time will
follow automatically the main-time and is programmable from 0 up to 255 minutes. During the main-time
both relays are active, during the pre-time and the post-time, only relay 2 is active. During the post-time,
the message “CL” (cool) will appear in the display. The timer can be stopped by pushing the Stop
button. If the Stop button is activated during the main-time, the post-time will automatically be initiated.
When the Stop button is activated during the pre-time, the main-time will be shortened with 1 minute.
