Temperature and humidity controller with RS232 output ^*Step required

TECHNICAL DATA

Transmitter temperature and humidity with two relay outputs.

Use Case exterior and interior.

Relative humidity, temperature probe on cable.

The measured values ​​are also converted to other interpretations of humidity: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy. Three inputs with two states.
