Product Description
- with integrated BCU
- with humidity sensor and room temperature controller
- with integrated push-button interface 2-gang
Intended Use
- Measurement of CO2 concentration, relative air humidity and air temperature
- Output of the measured values as telegram to the bus, e.g. for controlling fans or window drives via KNX telegrams
- Single-room temperature control in KNX installations
- Installation in flush box according to DIN 49073
Characteristics
- Limit value monitoring for CO2 concentration (max. 4 threshold values) and air humidity (max. 2 threshold values)
- Dew point alarm e.g. for cooling blankets and conservatories, to avoid mould formation
- Two binary inputs for connection of floating contacts e.g. buttons, switches, window contacts
- Logic gates for simple gating functions
