SENSOR INSTALLATION
Ground sensor ETOG, fig. 1+3:
For installation on outdoor areas where snow and ice is a
regular problem. The sensor must be embedded
horizontally with its top flush with the surroundings. Use
the accompanying installation plate.
The sensor cable must be installed in accordance with
current regulations. We recommend that cable pipes be
laid to protect the sensor cable. Detailed installation
instructions are supplied with the sensor.
Gutter sensor ETOR, fig. 2+4:
For installation in a gutter, or downpipe on the sunny side
of the building. It is important to ensure that the sensor
contact elements face against the flow of melt water. If
necessary, two sensors can be installed in parallel.
Detailed installation instructions are supplied with the
sensor.
Note that the pink and grey wires are not used.
