Setting values
In a typical application, the individual RXB room controllers signal their heat demand
direct to the primary controller by bypassing the RMB control unit (to the RMH760 in the
above illustration).
(1) and (2) stand for the distribution zone numbers.
This application can also be applied similarly to refrigeration distribution zones as
well as CLC and RAD applications.
If not 2-pipe fan coil is selected, heating and refrigeration demand is sent
simultaneously to generation.
