I have added the vision 1 system to a munckin contender to control water temps for infloor radiant. I am only using the outdoor sensor. I followed the manual, programmed the heat curve however the boiler continues to run at the setpoint used before the vision 1 was installed. I can scroll through the menu and it will show the outdoor temperature but it is not functioning as it should. I have emailed and called HT products but havent gotten a response. I am not a contractor however the boiler and system was installed by my father who is a licensed heating contractor but he is not trained on the vision 1 system. Any help is appreciated! thanks
