I has just installed NOMA 52-2570-6 thermostat. I find the current humidity display is wrong. It always display 26-29%. I am sure that my house real humidity should be 45-55%. If anyone know how to fix it, please let me know.

Thank you very much.

If no way to adjust is shown in your owners manual then it cannot be adjusted and you will need to obtain a warranty thermostat. If adjustments are available the follow the directions.

BTW make sure you check the humidity lever with a known reference since 29% is a possibility in the

Thank you for your reply. I can't find the way to adjust from the manual. I have a reference hydrometer showing current humidity was 45-55% in the same location, So I am sure the thermostat is wrong. I did reset (soft and hard reset) but it was sill same. Please help me to find out other solution. Thank you,

This should be your stat but with a little different number.

Nothing in the directions say how to adjust the humidity reading just how to adjust the humidity setting for the humidfier to turn on and off.

See actual page 11. It also states that it will only work if a humidifier is hooked up to the thermostat.

That is all the info I have.
