3.1 Functional description
Condair CRC serves for the humidity measurement in rooms. For the humidity measurement a capaci-
tive humidity sensor is used. The microprocessor samples the humidity once per second. It calculates
an averaging signal over a preset number of seconds and generates the output signal. The applied
measuring technology guarantees excellent reliability and long term stability. The output signal of the
sensor 0…10 VDC, 0…20 mA or 2…10 VDC, 4…20 mA may be customized by jumpers.
3.2 Safety
Please observe all local regulations concerning electric installations.
The installation work must be performed only by adequately qualied personnel (electrician or work-
man with equivalent training).
Warning - danger of electric shock! Before starting the installation work the unit to which the Condair
CRC or CRC-NA will be connected must be disconnected from the mains and may be reconnected to
mains only after all installation work has been completed.
Warning! The electronic components inside the Condair CRC or CRC-NA and the humidier are very
susceptible to electrostatic discharges. For the protection of these components, measures must be
taken during all installation work to prevent damage caused by electrostatic discharge (ESD–protection).
