THERMASREG
Mechanical temperature controller ⁄ wet room temperature controller THERMASREG
working without external voltage. It is used for moni toring and to control temperatures in heat generation plants, in heating, ventilation and air
conditioning systems, for ventilation, cooling and climate control in halls, cold storage rooms, greenhouses, nurseries, stables, breeding rooms, as
industrial room thermostat or surface-mounted thermostat in industrial applications as well as in wet room and outdoor areas.

The switch-on value is lower by the amount of operating difference.
Contact 2 - 3 breaks when temperature rises to the preset value.
The switch-off value is lower by the amount of operating difference.
Contact 1 - 2 closes when temperature rises to the preset value.
