    Just waiting until Monday to call Tarm, but I noticed the last couple of days my house temps have been lower than normal. It has a couple of degrees colder than thermostat is set at. I checked mt LK 130 thermostat and it had a reading of 68 degrees (I wouldn't mind 68 degrees in VT) but actually it was 31 degrees outside. The settings won't allow me to adjust that much of difference. Just wondering if anybody had any ideas what this could be? Bad outdoor sensor?

    Hi sparky, check the sensor specs possibly you could ohm it out to check accuracy. Are the wires tight in the terminals?

    Checked both ends are solid connections one is the probe the other has a modular plug like a phone
    I even tried to do a clear all reset

    Out of curiosity I’d take a ohm reading on the outdoor sensor before the modular plug and one at the lead ends?

    Not sure if I can do a ohm reading the probe is sealed at that end and the other end plugs into controller
    I will look at modular plug and see if I can get a reading
    I have some small probes I use on my generators it might work
    There are 4 contacts maybe they use the inner 2

    You don’t have to worry about a reading at the probe end , both leads will give a ohm reading that can be translated on a chart to temp. This will work if it’s a 10k ohm sensor, go online and look up a ohms to temp chart for a 10k ohm sensor, it’s a common sensor for this sort of thing , the leads have to be removed from the terminals to get a reading.

    All fixed. It was a bad probe. Good thing I live close to Tarm. Called Monday am had part Tuesday afternoon. Thanks TCaldwell for your help.

    Temp sensors can be flukie, a non moving part, works one day and not the next!
    Glad it’s resolved.
