sEnsOr InsTallaTIOn
Ground sensor - ETOG, figs 1+3:
For installation in outdoor surfaces where ice and snow are a
regular problem. The sensor must be embedded horizontally
with its top flush with the surrounding surface.
The sensor cable must be installed in accordance with current
regulations.
NOTE: We strongly recommend the use of cable pipes in order
to protect the sensor cable. Detailed installation instructions are
supplied with the sensor.
With ETOG-55, use the accompanying installation plate.
With ETOG-56, use the ETOK-1 mounting kit.
NOTE: Remove the installation plate from ETOG-55
before initial start-up.
Gutter sensor - ETOr, figs 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.
Outdoor sensor - ETf-744/99, figs 2+4:
Although ETF is designed for use with gutter sensor ETOR, it
can also be used separately for the detection of temperature
alone. The sensor should be mounted on the wall beneath the
eaves on the north side of the building.
water pipe sensor - ETf-522:
Is only used with hydronic heating systems to detect the
temperature of the supply and return water. Must be fastened to
the pipe directly with strips.
sensor cables:
With the exception of ETOG-56, which has a 32.8 ft (10 m)
cable, ETOG and ETOR sensors are supplied with a 82.02 ft
