Product details

KNX brightness and temperature sensor. The sensor detects brightness and temperature and sends these values to the bus. It features a temperature sensor and a brightness sensor with three universal channels for individual tasks or logical links. Temperature and brightness thresholds can be set in any combination. It includes a sun protection channel for controlling blinds or roller shutters. Functions include twilight threshold, brightness threshold, drive control, automatic sun control, teach-in, and safety. The automatic sun protection feature controls the blinds during the day. The teach-in object allows each brightness threshold to be reset at the touch of a button. It is suitable for installation on an external wall and comes with an integrated bus coupling unit. The bus is connected via a bus connection terminal. Power consumption is a maximum of 150 mW. The sensors have a temperature measuring range of -25 °C to +55 °C (±5% or ±1 degree) and a brightness measuring range of 1 to 100,000 lux (±20% or ±5 lux).
