Heating Cables
• establish the optimal positioning for the tem-
perature and moisture sensor – a place which
would be especially vulnerable to prolonged
low temperatures and increased moisture
deposition (e.g. in a shade or exposed to
wind operation) – place here the installation
tube of the sensor on the prepared hardened
base,
• feed the protective conduit with the so called
“draw wire” from the installation tube to
the switchboard (after the surface has been
completed, the protective pipe will enable
feeding the temperature and moisture sen-
sor’s wire),
In case of a significant sensor’s distance from
the switchboard, or bending of the protective
conduit, it is necessary to:
• install an additional sealed electric box “on
the way” to the board, or
• install the protective conduit with a twisted
pair screened control cable, min. 3-pair
– the sensor’s wire with the control cable is
to be connected with a heat shrink joint.

moisture sensor’s
installation
preparation
Note:
The protective conduit should be run
in such a way to enable the future exchange
of the temperature and moisture sensor,
if required.
