Advanced Virtual Thermostat

[MadMAX]

Hello,
does anyone got some experiance with the Advanced Virtual Thermostat?

My problem is that the times I set are act randomly.
I set the run time on 60min and the pause time on 30min but it switches my heater randomly on/off.

Can some help me with that?

I don't fully understand what you try to achieve. What kind of tempertature sensor do you have in your water heater. I guess it is a non z-wave sensor?
