12.6 Temperature sensors connection
The regulator is compatible only with CT4 and
CT2S sensors. The use of other sensors is
prohibited!.
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.
Mounting temperature sensor: 1 - pipe, 2 – clamps,
3 - thermal insulation, 4 - temperature sensor.
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.
12.7 Weather sensors connection
The regulator 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
regulator or properly to the used kind of
regulator.
The sensor should be screw to the wall. Access
to assembly holes is possible after unscrewing
the cover of the sensor.
12.8 Connecting exhaust sensor
The exhaust sensor should be fitted in the
boiler flue. The gap between the sensor and
the flue should be sealed. The sensor should
be installed by a qualified fitter, while
observing regulations applicable for chimney
systems. The emission sensor should be
connected to the sensor terminals acc. to The
emission sensor lead cannot touch hot
elements of the boiler and the flue, the
temperature of which exceeds 350°C. The
emission sensor should be installed in such
distance from the boiler at which it is not
directly exposed to flames, and where the
emission temperature does not exceed 450°C.
