5.3.5 Operation with digital backwards counter with target time setting,
adjustable from 1 minute to 99 days ( timer)
In timer operation, you can adjust the time the appliance runs at the set values. The ap-
pliance has to be in manual operating mode for this.
1. Press the activation key to the left of
the timer display. The timer display is
activated.
2. Turn the turn control until the desired
duration is displayed – in this exam-
ple 4 hours 30 minutes. The approxi-
mate end time is shown beneath, in a
smaller font.
Up to a duration of 23 hours 59 minutes, the time is displayed in hh:mm
(hours:minutes) format. For 24 hours and more, the format dd:hh (days:hours) is
used. The maximum duration adjustable is 99 days 00 hours.

4. Now, as described in chapter 5.3.2 , set the values for temperature
which you want the appliance to operate at. The set values can be changed at any
time while the timer elapses. The changes are effective immediately.
Setup
In , you can choose if the timer should be setpoint-dependent or not. This
determines whether the timer should not start until a tolerance band around the set
temperature is reached or if it should start immediately after activation (see page
52). The symbol on the timer display indicates that the timer is set to setpoint-
dependent.
Once the timer has finished, the display shows 00h:00m. All
functions (heating etc.) are switched off. If a fan was on, it will
continue running for a short safety period. In addition, an
acoustic alarm sounds, which can be turned off by pressing the
confirmation key.
