PROTRONIX NLII-RH | Combined sensor humidity/temperature Room sensor NLII-RH is used to monitor the air quality inside buildings and power 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 2x analog voltage/current output 2x output relay - 2x NO/C cascade switching not required maintenance during operation long life and stability Type of sensor NLII-RH -R NLII-RH +T NLII-RH +T-R ) It is possible to select by jumper type of analog output. Measurement of the relative humidity is based on the principle of capacitive polymer sensor. The sensor has built-in two separate analog outputs -one for the actual concentration of T and the other for the current relative humidity. If the sensor contains 2 relays can be set two switching modes: standard (always one relay switched according to one quantity), a cascade mode (according to a selected quantity switch two relays with different levels of switching). Cascade switching, for example, can be used to switch power air conditioning units. The two rotary switches can be independently set the level at which the corresponding relay switches. Sensor can efficiently manage ventilation and heat recovery units, based on current air quality. By three LED indicators can be easily checked the current air quality. Preferred eco level means good indoor air quality needed to achieve a sense of wellbeing and at the same time can reduce energy costs for heating or air conditioning. Based on these measurements can be directly controlled ventilation, air conditioning and heat recovery units in an efficient manner.
