KNX Sensors

Humidity - Temperature Controller


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

The GRHC-J0x-KNX device integrates humidity and temperature sensors.The GRHC-J01-KNX device integrates humidity and temperature 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 and humidity) 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
