Configuration Parameters
Parameter Description
1. Cross Over Source Sets the source that triggers switching PID sets. Process or Set
Point.
PID Set No. 1 - Prop Band
2. Heat (indirect) Sets the proportional band value for the heat outputs.
3. Cool (direct) Sets the proportional band value for the cool outputs.
PID Set No. 1 - Integral
4. Heat (indirect) Sets the integral value for the heat outputs.
5. Cool (direct) Sets the integral value for the cool outputs.
PID Set No. 1 - Derivative
6. Heat (indirect) Sets the derivative value for the heat outputs.
7. Cool (direct) Sets the derivative value for the cool outputs.
PID Set No. 1 - Dead Band
8. Heat (indirect) Sets the offset value of the heating proportional band from the set
point.
9. Cool (direct) Sets the offset value of the cooling proportional band from the set
point.
PID Set No. 1 - Cross Over Point
10. Cross Over Point Sets the process or set point value where the PID sets cross over.
Greater than or equal to this value activates this PID set. Must be
within set point range limits.
