C13 CMDE Control Mode:
0: both heating and cooling controlled by demand percentage
1: heating controlled from mixed air or supply temperature sensor, cooling by demand percent
2: cooling controlled from mixed air or supply temperature sensor, heating by demand percent
3: Both heating and cooling controlled from mixed air or supply temperature sensor
- 0 0 to 3
C14 MXWS Maximum Wind Speed: windspeed at which dampers are forced shut; override factor equals 0 m/sec 0 0 to 25
C15 MNWS Minimum Wind Speed: windspeed at which dampers are not effected; override factor equals 100 m/sec 0 0 to 25
