During normal operation the keys are used to browse
through the recorded temperature values. The (T1,T2,T3) sensor
symbols in the system diagram, show which measurement value
is currently being displayed.

The temperature in the upper part of the storage tank is only displayed if the T3 sensor has been connected.
In the event a sensor or its supply line short circuits, an animated Short Circuit Symbol is displayed instead of the
temperature.
In the event a sensor or its supply line is
interrupted, an animated Interruption Symbol is
displayed instead of the temperature.
If such a sensor fault occurs, the backlight
display alternately flashes red/yellow and a
warning symbol is displayed to indicate the fault.

The holiday function can be activated with this setting. The holiday function
is a storage re-cool function. If the operator does not use the warm water, the
storage tank may reach its maximum temperature early in the day. In this case
vaporization may occur within the solar unit and thus subjecting the unit to a
higher thermal load.
Note: This function should only be used if you are not at home for an extended
period of time. Please deactivate this function after returning back home to
prevent unnecessary loses of energy!
If while the holiday function is activated, a temperature 10K below the maximum
storing temperature is reached, this is recognized by the controller. In order to be
able to charge the storage tank the next day for a longer time and thus subjecting
the unit to a lower thermal load, the storage tank (e.g. during the night) attempts
to cool down to 35°C. For this purpose, if the storage tank is 8K warmer than the
collector, the pump is activated. If the temperature difference between the pump
and the collector is only 4K, the pump is deactivated again.
To activate the holiday function: Press and hold the set button for 2 seconds.
Symbol boxes will appear. Use the and buttons to scroll until the holiday
symbol appears. Press and hold the set button until a tick is shown next to the
holiday symbol. The holiday function is now set.
Press the ‘SET’ button again to deactivate the holiday function.
Press the button to reach the next setting.
