Thermostats terneo sneg + OSA for snow melting

terneo sneg + OSA takes into account all weather conditions

The thermostat is designed to work with anti-icing and snow melting systems. You can use it to heat any open areas, sidewalks and roads to avoid sleet.

terneo sneg + OSA will only switch the heating on when the air temperature is within the set limits and it detects precipitation on the surface of the precipitation sensor. The thermostat terneo sneg + OSA is designed to work with the precipitation sensor OSA, which is included in the set. The length of the connecting wire of the sensor is 10 m.

To melt the snow and avoid ice crusts forming on the surface of the sensitive contacts, the sensor is heated internally. If moisture is detected, the internal heater will run continuously and the load (heating cable) will turn on. 

Short video overview

Maximal efficiency

Optimal operation of the system is provided by temperature and precipitation sensors. Due to their combination, heating will be switched on under two conditions:

• air temperature will be within the limits at which snow can melt;
• there is snow that needs to be melted.

Thus, turning on the heating will only happen when it is actually needed. This allows you to more efficiently consume electricity and significantly save on payments.

Forced heating

You can turn on the heating manually when you wish, even if the sensors do not capture the need. The duration of forced heating can be set from 0.5 to 9 hours, and the countdown to the end of heating will be displayed on the screen.

The thermostat also has a post-heating function: after the precipitation sensor stops detecting the presence of snow on the surface, the system will operate for a given period of time (from 0.5 to 9 hours). This will ensure the complete melting of snow on the entire surface of the anti-icing and snow melting system.

Easy operation

The thermostat is set up with only three buttons! The digital screen displays the temperature of the air, as well as the precipitation sensor and moisture resistance on its surface. It provides easy menu navigation and displays system alerts.

Easy installation

The thermostat is installed in the switchboard on a standard 35 mm wide DIN-rail. The package contains everything necessary for installation: the thermostat itself, precipitation and temperature sensors with connecting wires 10 and 4 m long, accordingly.

Safe usage

The thermostat is equipped with an overheating protection system: if the temperature inside the housing rises above 80 ° C, the heating will stop. Heating will resume only after the temperature has dropped to 65 ° C.

Universal compatibility

You can use a thermostat with most of the heating cables on the market. The device works with both analog (R18) and digital (D18) sensors.
