Humidity Sensor

For use with Titon HRV Q Plus Range (B and B2 models only)


Room humidity sensor is used to monitor the air quality inside buildings and effectively control ventilation (HVAC) systems according to current levels of air pollution.

The sensor measures the relative humidity (RH) in air. It is suitable for living rooms, bathrooms, warehouses, ateliers etc.

Measurement of the relative humidity is based on the principle of capacitive polymer sensor.

The sensor has one analog output for the actual concentration of RH. The trigger level of RH output relay can be set by a rotary element.

Ventilation, air conditioning and heat recovery units can be directly controlled based on the output signal of the sensor in very efficient way.

Current air quality can be easily checked by three LED indicators. When ambient light is dimmed, the indicators turn off automatically to not disturb you at night.
