Have trouble with a Siemens tec hope someone can help. Using application 2281 one of our tec will no longer allow me to control the fan. When using global commander it just comes back as a fault, when using datamate it says "unable to memorize point". I have tried to cold start, that did not help. I reset it to factory defaults (App 2299) and I can control DO8 which is the fan control on app 2281 changed app back to a 2281 and I still can't control the fan. Anyone have any idea why it is doing this?
I tried to turn up the night set point to see if the tec would bring the fan on by itself, it would not.
