RCO2.T.RH.x RS485 – RLQ.T.RH RS485
Multifunction room bus unit CO2 and/or air quality sensor RS485
Application
The RCO2.T.RH.x RS485 or RLQ.T.RH RS485 multifunction room bus unit – whose signal communicates via RS485 and by means of Modbus®-RTU / S-Bus, records the CO2 content and the temperature and/or the air quality and the relative and absolute humidity in the room air, depending on the variant of the unit.
