Note Depending on the type of application, it may be that only “Primary Heat” or only “Primary Cool” is incorporated.
Caution With changeover applications, the current position of the control valve of the RXC controller is always sent to nvoHeatPrimary. As it is not possible to distinguish
between heating and cooling without additional information (integration of the NV “Unit Status”), the current valve position is mapped to @TCRn.OXWA.
