Electronic thermohygrostat HG 125

Humidity/temperature-based device control in operating environments from -30 °C even at very low humidity values – Made in Germany

Temperature and humidity at a glance

The HG 125 comes with two configurable switching contacts (RH/temp.) and enables electronic control even at very low humidity values in operating environments from -30 °C.

An external climate sensor continuously records temperature and humidity values at the measuring spot at a distance of up to 5 m, which are indicated in turns on the digital display of the HG 125.

The thermohygrostat is designed for direct connection to Trotec dehumidifiers with DIN socket for 7-pin plugs. If intending to use the hygrostat with 4-pin DIN socket Trotec dehumidifiers, the optionally available adapter transformer will be required in addition.

The thermohygrostat can also be used for combined heating with all Trotec devices which have a 7-pin DIN socket for connection, such as the multi air handlers TAC XT 18 and TAC XT 27. These devices can be temperature-controlled for decentralised room air heating via existing ventilation systems or textile air distributors using the HG 125.

Save electricity and money on dehumidification

With our HG 125 hygrostat, you save additional cash when dehumidifying or keeping damp rooms dry. The programmable switch is simply plugged into the dehumidifier with the 7-pin DIN connector to regulate dehumidification based on the measured humidity.

When the desired target humidity is reached, the hygrostat shuts down the unit, noticeably reducing the unit's energy consumption. The initial cost of the energy-saving HG 125 thus pays for itself in a very short time.

Furthermore, many dehumidifiers only have coarse target settings for optimum humidity. The HG 125 hygrostat allows the room humidity to be regulated in 2 % steps between 0 % and 100 % by connected dehumidifiers and thus offers a much more precise target humidity selection.
