KNX Sensors

Multisensor Controller - CO2 - Humidity - Temperature


The environmental sensors GRMC-J01-KNX and GRMC-J03-KNX are devices of the Line Glass series, they are wall-mounted and are finished with a white or black glass.

In the GRMC-J0x-KNX device there are 3 sensors available: temperature, humidity and CO2, this measure is detected by using an integrated probe specially designed to detect CO2 data directly and not through calculations based on other sensors.

The devices are also equipped with a 2-way connector on the rear side that can be configured as a digital or analogue input; in fact it is possible to connect an additional NTC probe to the device (GRTE-SEN or GRTE-SEN-2 - not included) to obtain a second temperature measurement.


  • The device includes 2 double-stage thermostats for controlling two distinct areas, both with an integrated PI controller for driving heating and cooling equipment, valves, 6-way valves, 2 and 4-pipe fan coils, etc
  • The humidity sensor manages the reading of the relative humidity in the environment and allows threshold control with hysteresis of humidification and dehumidification equipments
  • The devices embed 6 capacitive keys for the management of on / off commands, dimmers, shutters and blinds, execution and learning of scenarios, object sequences, local thermostat controls, etc
  • The device includes a RGB LED on the front side for displaying status (temperature, humidity and CO2) or other quantities available on the KNX bus
  • Device is intended to be used in British, German or Italian 2 module electrical box
  • Device is equipped with KNX communication interface
