8.2 Connection of temperature sensors
Use only following sensor types: CT10, CT6-P. The use of other sensors is prohibited. Sensors cables could be extended by a cable with cross-sectional
area ≥ 0,5 mm2, a total cable length ≤ 15 m. Boiler temperature sensor should be installed in thermostatic pipe installed in boiler. 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 environment.
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 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 betweens wires of the
sensors and hot parts of the boiler and heating installation. Wires of the sensors are resistant to temperature not exceeding 100ºC. From the regulator
can also be formed to correct an error reading from temperature sensors: circuit heating, external, return and boiler to the nearest 0,1°C. The value
correction set in:
