2-pipe fan coil unit with radiator

·

Heating or cooling

·

On/off, PWM or 3-position control of heating/cooling and radia-

tor actuators

·

Automatic or manual fan control, 1- or 3-speed

·

Automatic or manual changeover of heating/cooling mode

·

Multifunctional inputs for keycard contact, external sensor, etc.

The temperature in every room is acquired and controlled. Every room sends its heat/cooling energy request to the
heating/refrigeration plant. These plants are controlled depending on the outside temperature and the heat/cooling
energy requests received from the rooms. During nonoccupancy times (rooms not booked), the room temperatures
are automatically lowered via the integrated hotel booking system. Open windows are always automatically detected
and the temperatures of such rooms are lowered/raised to save heating/cooling energy. The room temperatures are
also slightly lowered/raised during the day, if the guest is not present.

Lighting control

Presence detectors (hotel card switches) help save energy by automatically switching the lighting off when the room
is not used.

Blinds control

Manual control without bus connection.

Remote control

Integration of a webserver facilitates remote control and monitoring on a PC or smartphone via webbrowser.
