Lowering water temps on Viessmann vitogas
I have a Vitogas 100 with one heating circuit and 2 zones. i have gone to constant circ. Rooms are still too warm. I have vitotronic 200 control with ODR. I have turned the curve down to .08 the water temp is still 133 degrees. Outside temp right now is 37. Does not seem to go lower when turning curve down. Is there a setting or code that reduces minimum water temp. I am trying to get rooms down to 69 but they are staying at 73 or 74. Have also reset the odr damped temp to read every 60 min. Any suggestions.
