The ETO is a thermostat for economical control of snow melting systems, e.g. in walkways, steps, parking areas, loading platforms - and also gutters and down pipes etc. Cold temperatures do not necessarily create ice unless moisture is present. The ETO detects both the outdoor temperature and moisture, and the snow melting system will normally only be energized when snow or ice occur. ETO is used for control of electric heating cables as well as other heat sources.
Setting of temperature with TEMP SET:
Selection of temperature setting to start the snow melting system, e.g. 1°C. By using a thermometer, the scale can be adjusted to correspond exactly to the outdoor temperature.
Setting of detecting mode with MOIST CONTROL:
Normal position ON: The snow melting system is energized only when the outdoor temperature is below the selected setting and the sensor is also detecting moisture.
Position OFF: The system is energized when the outdoor temperature is below the selected setting. This position is used on demand.
Manual snow melting:
The ETO has a built-in timer for manual snow melting. In this function the sensors are deactivated. With TIME SET it is possible to set the timer to 1-6 hours. The system is started
with TIMER START or by using a remote switch.
Remote day/week timer:
It is possible to connect a timer to start the snow melting system only in the pre-determined periods.
Ground sensor type ETOG:
Designed for embedding into the surface of the outdoor area. Detects temperature and moisture.
MOIST CONTROL in normal position ON: Detects temperature and moisture, the snow melting system will be energized only when the outdoor temperature is below the selected setting and snow occurs on the sensor.
Position OFF: The sensor detects temperature only.
Gutter sensor type ETOR:
Designed for mounting in gutters and down pipes etc. Detects moisture only. Is mounted in combination with outdoor sensor type ETF.
MOIST CONTROL in normal position ON: ETOR detects moisture, while ETR detects temperature. The snow melting system will be energized only when the outdoor temperature
is below the selected setting and snow occurs on the ETOR.
Position OFF: The ETF detects temperature only.
Outdoor sensor type ETF:
Detects temperature. Is used in combination with gutter sensor ETOR, but can also be used separately only for temperature detection.
