    Has anyone else suffered similar issues with their analogue temp probe?

    Device Details
    ProfiLux 3.1N
    FW-Version 6.38

    Official GHL Temp Probe with Mini-Din connection connected in to the lower din on the ProfiLux. When the probe is fully inserted it reads 14.8c and if you loosen the connection it climbs to 40c. I have replaced the temp probe with a brand new probe and the same issue happens.

    The ProfiLux was purchased second hand so I have no way on knowing if the issue was present before, however I was advised there were no issues.

    I have tried cleaning the din socket on the ProfiLux with a dry toothbrush and the same result.

    I have performed a re-calibration on the ProfiLux itself and via the control centre whereby the ADC values are set to 677 and 319.

    The temp holds at 14.8 and if you correct/adjust the temp it simply stays put and does not increase or decrease.

    I have changed the signal strength in the command centre and this has no affect at highest, middle and lowest strengths.

    As the din is on the main circuit board I suspect there should be no loose connection internally however I will disconnect the device and check for issues if no one has any other option to resolve the issue.

    I have reviewed the forum and and tried the previous posted suggestions to no avail.

    If anyone is able to assist with this I would be truly grateful.

    Do you habe a multimeter?
    Try to find the 2 Pins at the probe with About 1kO
    It should Change of you Change the temperature of the probe.
    Otherwise the probe is defekt.
    Second step connect a 1kO Resistor to the 2 Pins at the profilux. This should the profilux accept as 20 Degree Celsius. Otherwise you habe a Problem with the profilux.

    Hi Gandalf, many thanks for your reply.

    Will get on Amazon and purchase a multi-meter.

    Perhaps somebody from ghl will be so kind and name you the 2 pins you have to check.

    That would indeed be useful.

    GHL are you able to advise?

    Should be pin 4 and 5. You can test as Gandalf said ca. 1kOhm at 20 C, if the probe is good.220px-MiniDIN-6_Connector_Pinout.svg.png

    Hi MatthiasF,

    What would the resistance be at 26c?

    Hi MatthiasF,

    This should be around 1.1 kOhms.
