description
Individual room temperature control
The room operator unit (P37) acquires and controls
the room temperature and sends its positioning signal
to the valve actuator.
In the bathroom, the room sensor (P70) acquires and
controls the temperature and sends its positioning
signal to the valve actuator
Window contact
If one or several windows of a room are opened, the
operating mode changes automatically to Protection.
This means that heating or cooling energy is saved
since the system does not try to compensate for
energy losses.
Time program and hotel booking system
Time programs for up to 110 rooms or room groups
can be defined on the touch panel (UP 588).
A time program sets the periods of time the room is
not used. During these time periods, the operating
mode is set to Protection, resulting in a lower temper-
ature setpoint. After that, the setpoint is raised to the
Economy level.
Room automation can also communicate with the
hotel's booking system. When the guest checks in,
the room temperature is prematuraly raised to the
Comfort level. During the periods of time the hotel is
closed or in non-booked rooms, valuable heating
energy is automatically saved by changing the operat-
ing mode to Economy.
Presence-dependent heating control
When the presence detector (hotel card switch) sig-
nals that the room is occupied, the room temperature
is raised to the Comfort level. Then, it is lowered
again to the Precomfort level.
Presence-dependent lighting control
When the room is no longer occupied, the lighting is
automatically switched off after a delay time.

Blinds control
The weather station (AP257/32) with its built-in GPS
receiver measures solar radiation and controls shad-
ing to protect the façade against sunlight. Up to 4
façades can be selected for automatic and individual
control.
In cold winter nights, the blinds are lowered to im-
prove the building's thermal insulation. On sunny
winter days, the blinds are raised, allowing sunlight to
enter the room so that energy is gained.
When the room is occupied, automatic operation is
deactivated. The blinds can then be controlled via the
pushbuttons.
Protection of blinds
The weather station acquires continuously the wind
speed. If strong winds occur, the blinds are raised to a
secure position.
Remote control and monitoring
Using a webbrowser, all rooms can be controlled and
monitored via webserver (IP viewer). The following
parameters can be monitored:
If required, the following parameters can be changed:
