If the ¤ button is pressed and held for approx. 3 s, the INFO
TIME parameter appears.
With this parameter, the time it takes for automatic return to the
basic display can be specified.
OFF No return. The last selected information display
continuously remains in the basic display until the
next change.
1 ... 10 min Automatic return from the information level after the
specified time (in 0.5 minute increments).

If this button is pressed and held longer than 5 s in the basic
display, the controller is switched to manual mode. In this
operating mode, the required heat generator temperature is
specified manually with the input button
î according to the
respective heating need.
A controller set to manual mode has no effect in heat circuit
expansion.
The heat generator setpoint is set between the minimum and
maximum heat generator temperatures and appears flashing at
the bottom left-hand side. The current heat generator temperature
appears statically on the right-hand side in the basic display. The
set switching differential corresponds to the value of automatic
control and is symmetrical to the set value.
Controller malfunctions (emergency operation), errors
The maximum heat generator temperature limit is paramount to
the heat generator switching differential and stops the heat
generator in case of exceedance.
With control devices operated purely as a heating circuit
expansion, the setting of the temperature has no effect.
