Hi,

I found that on my setup, when the dew temp is negative the dewheater does not work well.

Dew point is -4°C when sensor temp is 4°C.
I need to set the gap between these temperatures to 10°C to activate the dewheater where initialy I set it to 2°C.

Is there a way that the "trigger temp" follow the negative state of the dew point to stay within the 2°C rather than modifiy it manually when dewpoint temp was negative ?

Can you clarify this a little, might just be me being slow but ....

If you have a limit of 2 then in your case

4 - 2 = 2 which is above the dewpoint so the heater will staff off

4 - 10 = -6 which is below the dew point so the heater will turn on

Am I missing something?

Many thanks

Alex
