12.7 TEMPERATURE SENSORS
CONNECTION
Wires of the sensors can be extended by
wires with diameter not smaller than
0,5mm
2 . Total length of wires in each sensor
should not exceed 15m.
Boiler temperature sensor should be installed
in thermostatic pipe installed in boiler.
Temperature sensor of hot water silo should
be installed in thermostatic pipe welded into
the silo. Mixer temperature sensor should be
installed in sleeve located in stream of
running water in pipe, but also it can be
installed on the pipe, on condition that it is
thermo isolated from the pipe.
Sensor must be protected from
getting loose from the surfaces to
which they are connected.
Good thermo contact should be maintained
between sensors and measured surface. To
this purpose thermoleading paste 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 10cm. It is not
acceptable to allow for contact between wires
of the sensors and hot parts of the boiler and
heating installation. Wires of the sensors are
resistant to temperature not exceeding 100
degrees C.
12.8 WEATHER SENSORS CONNECTION
The controller cooperates solely with weather
sensor type CT4-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 connect 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 controller.
The sensor should be screw to the wall.
Access to assembly holes is possible after
unscrewing the cover of the sensor.

12.9 WEATHER SENSORS CHECKING
Temperature sensors CT4/CT4-P can be
checked by measuring their resistance in
given temperature. In case of big differences
between measured resistance value and
values in table below, the sensor should be
replaced with a new one.
