DeltaSol® BX Plus
The DeltaSol® BX Plus is a compact multifunction controller for multi-store solar and heating systems. The intuitive commissioning menu leads you through the system configuration
by requiring the most important adjustments directly after connecting the
controller.
For an optimum overview, all sensor and relay allocations are listed in the service menu.
