Description

Room hygro-thermostat HYGRASREG® RHT - 30
Electronic HYGRASREG® RHT-30 room hygrostat and/or room thermostat with one continuous and two switching outputs, adjustable switching thresholds, with/without optional display for indicating ACTUAL humidity and/or ACTUAL temperature (accuracy class ±2.0% RH). The setpoints can be allocated to relative humidity and/or temperature.
The sensor device is suitable for regulating and monitoring relative humidity (humidifying and dehumidifying) and/or temperature (heating and cooling) e.g. in ventilation and air conditioning ducts, laboratories, production facilities, climate test chambers, indoor swimming pools, greenhouses, etc., for humidifying and dehumidifying equipment or heating system control. The measuring transducer has been 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.

Technical details

Function
Humidifying/heating:1st step: wire contacts 11 - 12.
If actual humidity falls more than 3 % RH / 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 % RH / 1 K (hysteresis) below
switching threshold S2, the changeover contact switches to 21 - 22.
Terminal 2: output relative humidity / temperature

Dehumidifying/cooling:

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.
Terminal 2: output relative humidity / temperature
