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 optimise 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
optimise 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 optimise 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.

Activation of the various OPERATING MODES may be affected by the time schedule functions or
heat pump service priorities (DHW, HEATING, COOLING, POOL).
NOTE

The activation of the HEATING and COOLING operating modes may be affected by service shut down
temperatures.
