Hi Archie32, thanks for sharing your experience. Initially I also followed the same procedure. Unfortunately, the calibration with the radiators turned off proved to be ineffective for me . With the radiators in operation, the difference between the temperature detected by the HR92 valve and that of ...

Thanks for the suggestion but my spoken English is much worse than the written one and I suppose the costs of the call from Italy, where I live, are not negligible...

If the HR92 isn't showing the correct temp to the room, then we normally advise you add a room thermostat (as the sensor for the room) to represent the air temp better (such as DT4R - https://thesmartthermostatshop.co.uk/product-category/honeywell-home-evohome/wireless-thermostats/) This is not the ...

Can't answer this sorry. Why are you offsetting the temp? Example. The temperature of my room is 20 degrees celsius. The temperature shown by the HR92 valve is 23 degrees celsius. By setting an offset of -3 the temperature displayed by the valve shows 20 degrees like the room thermometer. If the ...

To calibrate the temperature detected by the hr92 valve with that of a thermometer, is it advisable for the radiators to be turned off or on?
