Digital electronic regulator ETO2-4550-EU28

ETO2-4550-EU28 is a digital electronic controller for automated control of the snow and ice melting process, based on humidity and temperature measurements. The front of the controller is dominated by a data display and a programming button. It can operate one or two independent heating zones.

In the case of guiding the melting of snow and ice in gutters, it is equipped with a SZT-2 temperature sensor and one or two SOV-2 humidity sensors. When conducting the process of melting snow and ice on external surfaces, it is equipped with a moisture and temperature sensor type ETOG-55 and a temperature sensor STT-2 or with two sensors type ETOG-55. It has 3 relay outputs for currents up to 16 A and one relay output for alarm, which signals faults on the temperature sensor. The heating process can be conducted on the basis of temperature and humidity measurements, temperature only or manually, but with a limited operating time (up to 18 hours).
