11.6 Temperature sensors connection
Wires of sensors can be extended by wires
with diameter no smaller than 0,5mm
2
. Total
length of wires in each sensor should not
exceed 15m.
The boiler temperature sensor should be
installed in a thermostatic pipe installed in
the boiler. Temperature sensor of hot water
silo should be installed in a thermostatic pipe
welded into the silo. The mixer temperature
sensor should be installed in a sleeve located
in stream of running water in pipe, but also it
can be installed on the pipe, on condition
that it is thermally isolated from the pipe
Sensor must be protected from
getting loose from the surfaces to
which they are connected.
Good thermal contact should be maintained
between sensors and the measured surface.
To this purpose thermal grease should be
used. It is not acceptable to lubricate sensors
with water or oil. Wires of sensors should be
separated from network electrical wires. In
such a case wrong readings of temperature
may be shown. Minimum length between
those wires should be 10 cm. It is not
acceptable to allow for contact between wires
of sensors and hot parts of the boiler and the
heating installation. Wires of sensors are
resistant to temperature not exceeding
100
°C degrees.
11.7 Weather sensors connection
The controller cooperates solely with the
weather sensor type CT6-P. The sensor
should be installed on the coolest wall of the
building. Usually it is the northern wall,
under the roof. The sensor should not be
exposed to direct sunrays and rain. The
sensor should be installed at least 2 m above
the ground, far away from windows,
chimneys and other sources of heat.
To make the connection use wire with
diameter at least 0,5mm2 up to 25m long.
Polarization of wires is not essential. Second
end should be connected to terminals of the
controller or properly to the used kind of
controller.
The sensor should be screw to the wall.
Access to assembly holes is possible after
unscrewing the cover of the sensor.
11.8 Testing of temperature sensors
CT4 temperature sensor may be tested by
measuring its resistance at the given
temperature.
In case of significant
differences between measured resistance
and the values indicated in the table below -
replace the sensor.
