Æ AT 24h cooling start: Average outside temperature at
which the cooling is activated.
Each heating circuit can be set to its own Æ AT 24h cooling
start temperature.
Factory setting: 23 °C
Æ AT 24h current: Display of the currently calculated
24-hour average outside temperature.
The following status information is shown in the last line of
the display:
Heating demand:
The condition for heating mode is present.
Stand-by:
Neither the condition for heating mode nor that for
cooling is satisfied, or the transition time between
heating and cooling is in progress.
Cooling demand:
The condition for cooling mode is present.
