1.1 Intended use
The KLU 100 outdoor humidity transmitter is intended to be used to measure relative air humidity
and temperature in factories, warehouses and other buildings. The product lifetime decreases if the
environment is very cold (e.g. freezer rooms) or the air contains chemicals (e.g. chlorine at spas and
indoor swimming pools).
These transmitters are intended to be connected to building automation systems in the HVAC/R
industry.

2.4 Wiring
CAUTION: Device wiring and commissioning can only be carried out by qualified professionals.
Always make the wirings while the power is switched off.
24V 24 Vac/dc, < 1 VA supply
0V 0 V
Out1 Output 1: humidity output (%rH), 0...10 Vdc, 2 mA / 4…20 mA
Out2 Output 2: temperature output (°C), 0...10 Vdc, 2 mA / 4…20 mA
2.5 Setting the display mode (KLU 100-N only)
