User manual NLII-RH+T-RS485 | Combined RH/temperature sensor with RS485 Room sensor NLII-RH is used to monitor the air quality inside buildings and control ventilation (HVAC) systems according to current levels of air pollution. The sensor measures the relative humidity (RH) and temperature (T). It is suitable for living rooms, bathrooms, warehouses, ateliers etc. measures RH and temperature RS485 bus communication with Modbus RTU protocol maintenance during operation is not required long life and stability Description Measurement of the relative humidity is based on the principle of capacitive polymer sensor. The sensor provides two outputs over the RS485 bus one for the actual temperature and the other for the actual relative humidity. Sensor can efficiently manage ventilation and heat recovery units, based on current air quality. The current air quality can easily be determined by looking at the three LED indicators. The eco level means good indoor air quality that is needed to achieve a sense of well-being and at the same time optimal energy costs for heating or air conditioning. For information on the communication protocol, use the document NLII-Modbus-komunikace. Explanation of abbreviations and technical terms can be found on our website in the Glossary section.

(according to the quantity selected for indication) low concentrations of RH. Too dry air feels cooler as compared to equally hot but more humid air risk of drying of the mucous membranes - respiratory problems low temperature and its higher fluctuation is not economically profitable Typical T measurement accuracy Green LED lights: More than or equal to 40 % RH or 18 °C, less than or equal to 60 % RH or 22 °C. (according to the quantity selected for indication) optimal relative humidity for humans optimal balance of air quality and energy efficiency of ventilation and air conditioning CAUTION: Yellow LED lights: More than 60 % RH or more than 22 °C. (according to the quantity selected for indication) too high humidity, the risk of mold growth and associated health complications higher temperature T - high temperature can cause fatigue, restlessness, headache and feeling hot Warm-up: operational after 1 minute since power on. The declared accuracy is reached after 4 days of continuous power supply. It is necessary to avoid severe mechanical shock of the sensor. Sensor start after power on All three LEDs flash simultaneously until the first readings are available, but no longer than 10 seconds. Sensor failure indication All three LEDs are shining permanently.
