Room hygrostat HG 120 with 4-pin DIN plug
External hygrostat for humidity control and monitoring - Made in Germany
The solution for unattended continuous operation of dehumidifiers
With 4-pin DIN plug for the humidity-dependent control of desiccant dehumidifiers of the TTR series (TTR 160 to TTR 500 D) and other devices with a DIN socket for external switching.
The Trotec hygrostats HG 110, HG 120 and HG 135 are technically identical and only differ in their connection type. The HG 110 has a 6.35 mm jack plug. The HG 120 has a 4-pin DIN plug and the HG 135 is offered as a 230 V version with a maximum switching load of 10 A and a CEE 7/3 combination socket.
The external hygrostat HG 120 in combination with the matching dehumidifier serves as a two-point controller for controlling the relative humidity, for example, on indoor construction sites, in basement rooms, in climatic cabinets or for controlled dehumidification of office and computer rooms. Other areas of application are warehousing for goods or foodstuffs, cold storage rooms for fruit and vegetables, greenhouses of horticultural businesses, textile industry, paper and printing industry, film industry, hospitals. Wherever air humidity needs to be controlled or monitored, the HG 120 with the associated dehumidifier is generally applicable.
Mode of operation and mounting location
The mounting location should be chosen to ensure a representative humidity measurement, i.e. the humidity readings at the mounting location should match those of the room and the humidistat should be located in the air flow. The room hygrostat responds quickly and accurately to changes in humidity. By adjusting the setpoint knob, the lever system is intervened in such a way that when the set humidity is reached, the internal microswitch is actuated.
Save electricity and money on dehumidification
With our hygrostat HG 120 you save additional cash when dehumidifying or keeping humid rooms dry. The programmable switch is simply plugged into the dehumidifier with the 4-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 purchase costs of the energy-saving HG 120 thus pay for themselves in a very short time.
Furthermore, many dehumidifiers have only rough target settings for the optimum humidity. The HG 120 hygrostat allows the room humidity to be regulated in 1 % steps between 40 % and 90 % by connected dehumidifiers, thus offering a much more precise target humidity selection.
