H3021 relative humidity and temperature controller with two COMET relay outputs

Description

H3021 Relative humidity and temperature controller with two relay outputs for indoor and outdoor use.

The controller can convert the measured humidity value into a format: dew-point temperature, absolute humidity, specific humidity, mixing ratio or other. The built-in capacitive polymer humidity sensor ensures long-term stability of the humidity calibration, independent of the influence of water and condensation. The controller is equipped with three binary inputs for water, smoke, glass break or door contact detection.

The device is equipped with a T+RV probe (sensor) with a 1, 2 or 4 metre cable.
