9.3 Manual and automatic summer mode
Manual summer mode occurs if no temperature step is selected. The temperature symbol on the main
menu is then completely empty.
If the electrical re-heater is activated, it will switch off during manual summer mode. Manual summer
mode goes automatically to step 1 (setpoint 12 °C) after two minutes if the supply air temperature is
+5 °C or below.
If a water heater battery is installed and activated, the manual summer mode goes automatically to step 1
(setpoint 12 °C) if the outdoor air or supply air temperature is +5 °C or below.
The unit will automatically alternate between winter operation with heat recovery and summer operation
without heat recovery.
9.4 Cool recovery
If the outdoor air is warmer than the extract air and the supply air is above the setpoint, cool recovery
occurs. This condition blocks the heat regulation process.
