HG 125 Trotec Climate Controller

Thermo-hygrostat HG 125 - TROTEC

Monitor temperature and humidity in real time

The HG 125 integrates two independent switching contacts (relative humidity and temperature) for precise electronic control, even in extreme conditions down to -30 °C.

An external climate sensor ensures continuous measurement of temperature and relative humidity, installable up to 5 meters away. Values alternate on the digital display of the HG 125.

Optimal compatibility

This thermohygrostat connects directly to dehumidifiers equipped with a 7-pin DIN socket. For devices with a 4-pin DIN socket, an optional adapter transformer is required.

The HG 125 also pairs with combined heating systems featuring a 7-pin DIN connection, such as the TAC XT 18 and TAC XT 27 multi-airhandlers. These units provide decentralized ambient air heating via ventilation networks or textile diffusers, automatically controlled based on measured temperature.

Significant reduction in energy costs

The HG 125 hygrostat optimizes power consumption during dehumidification or dry keeping of damp rooms. Simply plug the programmable switch into your dehumidifier via the 7-pin DIN connector to activate automatic regulation based on ambient humidity.

As soon as the target humidity level is reached, the device automatically shuts off, considerably reducing energy consumption. The investment in the HG 125 thus pays for itself quickly thanks to its economical performance.

Unlike the approximate settings of many standard dehumidifiers, the HG 125 offers fine regulation of ambient humidity from 0% to 100% in 2% increments, ensuring optimal precision of target values.

Practical advantages:

Two independently configurable contacts for temperature and relative humidity

External climate sensor with 5-meter cable

7-pin DIN connector with 5-meter cable

Programmable adjustment ranges: 0 to 100% RH for humidity, -30 °C to +70 °C for temperature
