Explain offset

edited December 2019 in Technical Questions
I’m not sure which way the offset works, if the valve says it’s 19 but it’s actually 22 does that mean the offset needs to be 3, as in it’s 3 degrees higher?
Or do you need to tell it -3 as in the valve is registering 3 degrees lower than actual temp?
I think tado should show a couple of examples on how to correctly set this to work properly.


  • First description is correct. Reading here offset on the TRVs is pretty much useless. Either mount them horizontally ( bit of plumbing required), get another TRV and use as external temp monitor or get the expensive wall thermostat.

    Has various suggestions
  • Mine are mounted horizontal, I was just wondering if to set +3 or -3 in the example. I will be getting a temp gauge to check real temp compared to the valves temp.
