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 example 4
hours 30 minutes. The approximate 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 23 hours.
3. Press the confirmation key to confirm.
The display now shows the remaining
time in a large font and the approximate
end time in a smaller font beneath.

not start until a tolerance band around the set temperature is reached or if it should start
right after activation (see page 42). If the timer runs setpoint-dependent, this is indicated by
the symbol in the timer display.

on running for a short safety period.
