Product family: ETS.
Physical sensors: Product type temperature.
Intended use: Individual room temperature control in KNX installations. Mounting in a device box with dimensions according to DIN 49073.

Product features include measurement of room temperature and comparison with the set temperature. Setpoint specification is achieved by selecting the operating mode. Operating modes include comfort, standby, night operation, and frost/heat protection. Heating and cooling operation includes basic and additional stages. Operation is exclusively via the bus.

The button interface has four inputs or two outputs and two inputs, suitable for window contacts, buttons, LEDs, etc. The functions of the inputs include switching, dimming, shutter control, light scene secondary control, and brightness or temperature value provision.
