Stage 3: Temperature and
moisture sensor’s
installation preparation
• 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).
• Feed the protective conduit with the so called
“draw wire” from the planned sensor’s posi-
tioning to the switchboard (after the surface
has been completed, the protective conduit
will enable feeding the temperature and
moisture sensor’s wire).
Note:
Fill the spot selected for the sensor’s installa-
tion with material to be removed after concre-
te or asphalt has been cured (e.g. a wooden
block of 100 x 100 mm and the height equal to
the planned thickness of the finished surface).
!
Note:
The protective conduit should be run in such
a way to enable the future exchange of the tem-
perature and moisture sensor, if required.
!
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 (e.g.
LIYCY-P 3x2x1.5)
– the sensor’s wire with the control cable is to be
connected with a heat shrink connecting joint.
