4. Now, as described in chapter 5.3.2 , set the values for temperature and pressure ,
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.
In
Setup
, 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.
