Cooling: this is “summer” operating mode; the machine is configured for cooling.
Heating: this is “winter” operating mode; the machine is configured for heating.
Auto: The machine is configured to switch automatically from cool to heat mode and vice versa. Depending on the
temperature detected by the water sensor (2-pipe system) or air sensor (4-pipe system or 2-pipe with INTEGRATED AND
AUTOMATICALLY ADJUSTING electric heaters).
The utilities controlled in the various operating modes are shown in the table below:
Mode Setting Utilities controlled
