3 Operation
Setpoints for room temperature and fan stage – Profiles
The selection of the current setpoints for room temperature and fan stage is based on so-called
profiles that are specified by the user on site. The following situations are covered, e.g.:

Figure 1: Temperature setpoints for heating and cooling for the individual profiles
- "Comfort" profile:
The hotel room is occupied, the hotel guest is present. The room temperature is set to a
comfortable value.
- "Comfort–" profile ƕ (if a hotel card switch is installed):
The hotel guest is not present. The setpoints are set to an energy saving level; the values
of the "Comfort" profile can be reached quickly.
As soon as a hotel guest inserts the hotel card into the available hotel card switch, the
controller switches to the "Comfort" profile.
- "Eco" profile Ɣ:
It is night, the controller controls the connected fan coil units and puts them into an energy-
saving and silent operation.
- "Standby" profile Ɠ:
Currently the room is not in use. The energy level is set such that only minimum heating/air
conditioning costs are incurred by the owner.
- "Building Protection" profile Ɩ:
When the environment raises or lowers the room temperature to a level that could damage
the building, the controller automatically activates the building protection operation. The
setpoint temperatures are permanently set (heating: + 7 °C; cooling: +45 °C).

Operating modes and display icons
The device compares the current room temperature with the setpoint temperature and controls
heating or cooling devices according to the current demand. The setpoint temperature depends
on the currently set profile and can be changed by the user, depending on the setting. The
current operating state is displayed.
