Introducing OJ Electronics Type ETO2 Control & Sensors System for Ice & Snow Melting

We are very impressed with OJ Electronics powerful, highly capable new controls:

OJ Electronics Type ETO2 Control & Sensors System for Ice & Snow Melting

Energy efficient control of ice and snow melting – Type ETO2

An intelligent all-in-one solution for ice and snow melting usable for all applications within hydronic as well as electrical heating.

Optimal operation is ensured due to output control which makes the system both effective and economical.
ETO2 offers you the possibility of snow melting – the green way.


  • Electronic on/off control up to 11 KW
  • 2 zone control, individually controlled at the same time
  • Economical control – minimizing energy consumption
  • Adjustable moisture sensitivity
  • Detection of temperature and moisture
  • Display and “knob wheel” for easy programming
  • Control of electrical or waterbased ice and snow melting systems
  • Language options

Green Comfort – Save 66% CO2
Thermostat functions ensuring minimal energy comsumption

Using readings from temperature and moisture sensors, the controller ensures economical control of power consumptions when keeping outdoor areas and roofs free of ice and snow. The moisture sensor is installed in the surface of the outdoor area or placed in the gutter. As soon as moisture is detected, the ETO2 controller activates the snow melting system.
Once the sensor has dried out, the thermostat immediately goes in afterrun and the system will continue to provide heat for a chosen time.

For Gutters – ETO2-4550, ETOR-55 and ETF-744/99:
The sensor type ETOR is designed for mounting in gutters and down pipes etc. ETOR detects moisture, while ETF detects temperature.

For Outdoor areas – ETO2-4550 and ETOG-55 is used:
The sensor type ETOG is designed for embedding into the surface of the outdoor area. ETOG detects ground temperature and moisture. The air sensor type ETF-744/99 can be used for measuring rapidly temperature decreases.

Remote control:
It is possible to control the ETO2 from an external signal (day/week timer, GSM-module or other signal source) The ETO2 can be switched on/off (standby) and the heating system can be forced on, in the after run time that has been set in the menu.
