PROTRONIX NLII-RH+T-SX Room Sensor User Manual
Room sensor NLII-RH is used to continuously monitor the air quality inside buildings and then 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
- SIGFOX wireless communication
- maintenance during operation is not required
Description
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
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 detailed information on the communication protocol, use the document NLII-
Sigfox-Communication.
Technical data
Explanation of abbreviations and technical terms can be found on our website in the Glossary section.
Analog output values versus actual RH
Typical RH measurement accuracy at 25 °C
Analog output values versus actual T
Typical T measurement accuracy
LED indication description
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.
CAUTION:
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.
Electronic board controls and terminals
Terminals
Jumpers
- JP1 – Current output offset RH
- JP2 – Current output offset T
- JP3 – Voltage/current output T
- JP4 – Voltage/current output RH
- JP6 – LED indication settings
Jumpers on the electronics board
Factory settings
- LED indication: by RH, indication turns off when ambient light dims
- T analog output: voltage output
- RH analog output: voltage output
Example of RH sensor connection for direct EC motor control using 0-10 V signal
If you connect other devices to the same AC power source as the NL sensor, it is necessary to meet GND wiring of all analog inputs and outputs, as well as power wires.
Sensor assembly
Box color
Front: White – RAL9016
Base: gray – RAL7035
Way to use
The product is intended for indoor use only. You can read the recommendations
for sensor placement on our web pages.
End of product life
Discard the product in according to the electronic waste law and the EU
directives.
Disassembly
When disassembling, be careful not to rip-out the antenna cable. It connects the antenna in lower part of the sensor with the electronics in the upper part.
Dimensions
The producer reserves the right of technical changes in order to product improvements its properties and functions without previous notice.
