    Exclamation HR92 wildly inaccurate

    Hi

    I have a new HR92 on a radiator that is reporting very confusing temperatures and hence very variable heating. Others in the house work fine.

    I put a Sanus digital thermostat on top of the HR92 to compare the readings as closely as possible. Here's a sample:

    HR92__Sanus
    17_____19.5
    17_____22.5
    20_____18.5
    20_____23.5

    Readings from analogue thermometers and the feel of the room generally agree with the Sanus

    The difference is not a constant or even in the same direction so using the calibration offset isn't going to help.

    Any solutions or shall I just get a replacement?
