Hello Mark!
Using an external trigger does not work well at all.
I would try the following first. Set the Offset to 0 degrees then the Eve Thermo to 23 degrees. Wait for 2-3 hours and measure the temperature in the middle of the room with a thermometer. Would ist be 19,5 degrees, set the offset to -3,5 degrees. I would give it a try. Best regards, volker
