Controller 2
In the case of a typical application, the individual RDF / RDG room thermostats –
when used with the RMB975 central control unit – signal their heat demand directly
to the primary controller (in the above example to the RMH760).
(1) and (2) designate the numbers of the distribution zone.
 This type of application can analogously be applied to refrigeration distribution
zones
 If no 2-pipe fan coil is used, heat and refrigeration demand signals are sent
simultaneously to the primary plant
