    If anyone was interested in repairing or making such a sensor, then I make the task easier because it took me a few hours to search the catalogs of the actuator that is in this sensor. KTY81 / 110 the sensor under the name CT4 is found in ecoMAX controllers and probably in many others
    auxiliary materials

    And what is the resistor in the outside temperature sensor
    CT-4P? Maybe someone knows because after inserting the resistor PT 1000 shows 30C too much?

    I gave the ready answer, it is not a resistor, but a temperature sensor KTY81 / 110 search google I thought I described it clearly

    For CO and DHW temperature sensors, the KTY81 / 110 sensor fits,
    whereas when connecting KTY81 / 110 as an external temperature sensor, the PLUM controller shows about 20st too little.

    It looks like the outdoor sensor and chimney sensor use the same sensor - PT106053 / SA10201521. I found 2 variants of this sensor.
