HR92 temperature adjustment

[KeironS]

I know you can adjust the temperature calibration on an HR92 radiator valve having read a few threads discussing this but, and forgive me for being a Geologist where +/- 1 million is usually close enough, I can't get my head around which way to adjust.

I have 1 room where the HR92 is kind of cramped into a "cold" corner. The sensor shows the room as 17ºC as does the EvoHome Controller but 3 independent thermometers in the middle of the room all show a 3ºC difference in actual temperature. In this case the room appears colder than the sensor thinks it is. I'm presuming the sensor is reading the local temperature right by the radiator and suffering a lack of clear convection to "read" the room.

So do I calibrate with +3 to indicate the sensor is reading high or -3 to indicate the room is cooler?

This is the only room I'm particularly worried about as the rest of the house either has good circulation or has wall mounted thermostats.

Cheers

I've never had to do this... But I believe you would set negative if you want the room to be hotter than it thinks it is.
