DESIGO building automation system

The DESIGO RXL hardware
The range consists of compact controllers and QAX3…, QAX8…, QAX9… room
units for HVAC operation. The compact RXL21.1 and RXL22.1 room controllers are
load with comprehensive standard applications for fan coils.
The required application is enabled in the commissioning phase.
DESIGO RXL software
Each DESIGO RXL room controller is loaded with HVAC application software which
include one or more applications. The desired application can be enabled during
commissioning. Our compact RXL21.1 and RXL22.1 room controllers are
optimized for fan coil applications. The RXL24.1 room controller is designed for
radiator and chilled ceiling applications. They can be installed directly in the fan coil
unit, in control panels or on ducting. They also communicate with the Synco 700
control system.
Room unit: The key to individual comfort
The DESIGO QAX.. room units cover a wide spectrum of possible operating
scenarios. The range includes units which measure the room temperature and
allow setpoint adjustment, operating mode selection or fan-speed control and an
LCD display. The QAX9.. room units are wireless devices. Design and ergonomic
operation are optimized.
The QAX84.1/PPS2 room unit is based on the device QAX34.1 (software and LCD are
identical) and are installed flush mounted as a variant. As a consequence, you can
combine the device with third-party switching programs.
The QAX5…integrated room unit works with LONWORKS combines the operation of
HVAC, lighting and blinds in a single device. The keypad can be configured with
the combination of buttons and switches best suited to the application.
