HYGRASREG RHT - 30
Electronic room hygrostat and/or room thermostat HYGRASREG
thresholds, with ⁄ without optional display for indicating ACTUAL humidity and/or ACTUAL temperature (accuracy class ± 3 % r.H.). The setpoints can
be allocated to the relative humidity and/or to the temperature. It is suitable for regulating and monitoring relative humidity (humidifying and
dehumidifying) and/or the temperature (heating and cooling), e.g. in ventilation and air conditioning ducts, laboratories, production facilities, climatic
test cabinets, indoor swimming pools, greenhouses, etc., to control humidifying and dehumidifying equipment or heating system control. The measuring
transducers are designed for exact humidity/temperature measurement. The RHT-30 uses a digital, long-term stable sensor as a measuring element. It
is used in dust-free, unpolluted, non-aggressive air.

1st step: wire contacts 11 - 12.
If actual humidity falls more than 3 % r.H. / 1 K (hysteresis) below switching threshold S1,
the changeover contact switches to 11 - 12.
2. step: wire contacts 21 - 22.
If actual humidity falls more than 3 % r.H. / 1 K (hysteresis) below switching threshold S2,
the changeover contact switches to 21 - 22.
Terminal 2: output relative humidity / temperature
1st step: wire contacts 11 - 13.
When actual humidity exceeds switching threshold S1, the changeover contact switches to 11 - 13.
2. step: wire contacts 21 - 23.
When actual humidity exceeds switching threshold S 2, the changeover contact switches to 21 - 23.
