3.4. Mode
This field shows the icons that indicate the operating modes that are active. Several operating modes can be viewed simultaneously,
depending on the heat pump model and the configuration set up by the technical service.
DIRECT HEATING Mode / DIRECT COOLING Mode
The heat pump sends hot / cold water directly to the heating / cooling system and adjusts the power supply to the
consumption of the home. The outlet temperature and flow are constantly controlled to optimize installation
performance.
These modes are activated when the heat pump receives a heating / cooling demand from the interior terminals
installed in the home (thermostats, th-Tune terminals, thT terminals or TH sensors).
BUFFER HEATING Mode / BUFFER COOLING Mode
The heat pump sends hot / cold water to the buffer storage tank of the heating / cooling system. The power supply,
flow and outlet temperature are constantly controlled to maintain storage tank temperature and optimize
installation performance.
These modes are activated when the buffer storage tank temperature is lower / higher than the differential of
start-up temperatures.
DHW mode
The heat pump sends hot water to increase the temperature of the storage tank so it reaches the DHW setpoint
temperature as soon as possible.
This mode is activated when the DHW storage tank temperature is lower than the differential of start-up
temperatures.
POOL mode
The heat pump sends hot water to the pool production exchanger and adjusts the power supply. The outlet
temperature and flow are constantly controlled to optimize installation performance.
This mode is activated when the heat pump receives a demand for pool production.
LEGIONELLA PROTECTION Mode
The heat pump raises the temperature of the storage tank to the final temperature set by the technical service for
the legionella protection program. Heating is produced initially by the compressor, followed by activation of the
auxiliary DHW system, if there is one, until the final temperature is reached.
This mode is activated in compliance with the provisions in the weekly legionella protection program.
DEFROST Mode
The heat pump interrupts its normal function, to eliminate the existing frost in the battery. Once the defrost ends,
the heat pump will continue with the normal operation.
This mode is activated according the parameters configured in the installer menu.
ANTI-FREEZE mode
Even if there is no request, the heat pump activates the heating production, activating the compressor if necessary
to prevent the water in the heating circuit from freezing.
DRYING HEATING FLOOR mode (Only visible with floor drying activated)
The heat pump sends hot water directly to the underfloor heating system, adjusting the delivered temperature to
the one previously set in the "underfloor heating - floor drying" menu and running for whatever period of time has
been set in that menu.
Note: After all the stages set in the floor drying program are completed, the heat pump returns to normal operation
and this screen disappears. If there are requests for the enabled services, the heat pump deals with them.
