Assortment / System Description

Room controllers RXB/RXL and central control unit RMB795B

Controls providing room functions should be located on the same KNX line as the

devices with which they exchange data via the KNX bus, which means:

• RXB/RXL room controllers and RMB795B control unit on the same KNX line

In every room controller, the heat and refrigeration distribution zone is to be

configured with a zone address. Data exchange always takes place within the line.

On a line with RXB/RXL room controllers, the RMB795B central control unit is used

as a "collector".

In the "collector", the heat and refrigeration distribution zone on the generation side

is configured with a zone address. Data exchange in LTE mode takes place via line

couplers (Lc) and area couplers (Ac).

The "collector" forwards the room controllers’ heat/cooling energy demand to the

Synco 700 controllers for the production of heat and cooling energy.
