Function Calculates an output according to a user-defined and adaptable heating
compensation curve. The output is used as a setpoint for a discharge control loop.
For example, HCA can be used to calculate a discharge air temperature setpoint.
Software calculates the discharge air temperature setpoint from the room
temperature setpoint and the outdoor air temperature using the heating
compensation curve. See Operation note in this section for more details.
Inputs Four analog inputs (X1 through X4) and one digital input (XD5), where:
X1 (Excel Web / Excel Web II: TSet) = Room temperature setpoint
X2 (Excel Web / Excel Web II: TOat) = Outdoor air temperature
X3 (Excel Web / Excel Web II: TRm) = Room temperature
X4 (Excel Web / Excel Web II: TWtr) = Discharge boiler water temperature
XD5 (Excel Web / Excel Web II: SPmp) = Heating pump status
The room temperature setpoint (X1) must have a user address.
The X3, X4, and XD5 inputs are only required and only appear when working with
adaptation.
Output One analog output Y (Excel Web / Excel Web II: TWtr).
