In the case of a typical application, the individual RDF / RDG room thermostats
send 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.
