Depending on the configuration of your installation, some of the operating modes listed may not
be selectable. Please read carefully the following sections, which describe in detail the operation of
these modes.
4.2 AUTO mode
This mode is selectable only if the heating/cooling installation is ready for operation in Cooling
mode (cooling floor, fan coils, etc.) and the heat pump is configured for this purpose.
In this operating mode, the electronic controller of the heat pump, depending on the temperature
outside the home, will automatically decide when to activate the heating or cooling mode of the
heating/cooling installation. If the outside temperature is below 15°C, the heating mode will be
activated; if the outside temperature is above 25 ºC, the cooling mode will be activated. If the
outside temperature is between 15 ~ 25°C, the last operating mode will remain active. For more
information on each of these operating modes, read the following sections of the manual carefully.
This mode will operate only on the heating/cooling installation, disabling the DHW production
service, if any.
