• With the optional infrared presence sensor the set point can be adjusted or the round flow cassette switched off when there is nobody
in the room. Up to 27% energy can be saved (estimated) with this new function. If no presence is detected in the room for 15mins,
the set temperature is changed until a minimum temperature (for heating) or maximum temperature (for cooling) is reached.
When selecting the setback function, the unit will maintain the temperature within a preset minimum and maximum temperature,
when there is no presence detected in the room for 1 hour.
