the appliance is switched off. Automatic operation is not possible from this
state. To switch the appliance on press the I/O key.
Important Note:
The I/O key overrides all other functions and is available in any operating
state (an “emergency ON” switch so to speak).
The I/O key interrupts any preceding operating state by switching the appliance “OFF“ or
“ON”. If the appliance has been switched off with this key you can only switch it on again by
pressing the I/O key again. Note: In this state, i.e. when the “stand-by dot” is displayed the
appliance will not react to signals from an external or internal controller! External or
internal controllers will identify the appliance as “not ready” in this state, even if it readily starts
up when you press the I/O key. The desired thermal output can be adjusted at any time via +/-,
even when the appliance is off. The “Menu” remains accessible when the appliance is switched
off.
5.8.1 Switching the appliance on via the I/O key
Pressing the I/O key switches on the device.
After this the display briefly shows “ON” and then, for a few seconds,
the
programme
version
installed,
for
ex.
“P3 400”. During these seconds the system checks whether all
functions are o.k. In the event of an error the appliance does not start
and instead display the relevant error message (see Chapter 0 ff.). If
everything is in order the appliance then enters preheating
programme “A” and eventually heating programme “H”.
5.8.2 Switching the appliance off via the I/O key
Pressing the I/O key switches on the device. and the message “OFF”
will briefly appear in the display.
After “OFF” has been displayed the appliance enters the fan after-run
phase (“G OFF”) and finally goes into stand-by “stand-by dot”).
5.8.3 Reset via the I/O key
The I/O key also allows you to restart the appliance after a class 1 error has occurred. The only
way to restart the appliance after a class 1 error has occurred during operation is to press the
I/O key. See Chapter 0 on this.
