4.7.2. Connecting external temperature sensor
This is applicable only to Termo Extra boilers with option C or W, Termo Blok boilers with
option C and Termo Blok PTV boilers.
External temperature sensor (delivered with boiler) must be fitted in such manner that it is not affected
by sudden temperature changes (exposure to direct sunlight). When fitting sensor please observe the
arrow marking top position (it can be seen when protective cover is removed).
Connector for outdoor temperature sensor has factory mounted resistor for testing boiler at -13ºC.
After installation and initial testing, resistor must be removed and wires from external temperature
sensor must be connected.

4.7.3. Connecting domestic hot water temperature sensor
This is applicable only to Termo Extra boilers with option C and Termo Blok PTV boilers.
Domestic hot water temperature sensor (delivered with the boiler) must be fitted in such manner that
reading of correct cylinder temperature is ensured. Water cylinder usually has a spot provided for
inserting temperature sensor. If this is not the case temperature sensor must have contact with metal
part of the cylinder (under the insulation).
