4.2.7 ECO function
Operation in ECO mode reduces energy consumption and noise by controlling compressor speed
as a function of temperature. ECO mode can be selected only when using an NTC temperature
sensor.
It is only possible to select ECO mode when running a single configuration or a twin configuration
with Synchronic mode turned ON.
In case of switching from selectable ECO mode to non selectable ECO mode, the ECO function is
going to be switched OFF autmatically.
In ECO mode,
• when operating below ECO temperature, compressors run at the set ECO speed, and the
Start speed setting will be overruled, if it differs from ECO speed.
• when operating above ECO temperature, the compressors run at Requested speed.
