Description of functions
Synchronization of clock time
The clock time can be set on any of the Synco 700
controllers (RMH, RMS, RMB) and is synchronized
throughout the system.
Time switch
Geographical zone
The time switch master – in this case the central
control unit (RMB) – forwards the Comfort, Precomfort
and Economy modes to all room controllers (RXB) in
its geographical zone. This means that all room con-
trollers (RXB) operate according to the time switch of
the time switch master.
With room controllers (RXB), the address of the time
switch master’s geographical zone must be set on the
slave zone’s time switch.
Holidays / special days
Geographical zone
With the room controllers (RXB), it is not possible to
set a holidays / special day zone. This information is
distributed in the geographical zone via the time
program.
Outside temperature
Outside temperature zone
The central control unit (RMB) distributes the outside
temperature in outside temperature zone 1. All de-
vices in outside temperature zone 1 operate with the
same outside temperature.
Optimization of energy usage room
Heat distribution zone
When the room calls for heat, the room controller
(RXB) forwards a heat request to the central control
unit (RMB) via heat distribution zone 2.
Refrigeration distribution zone
When the room calls for cooling, the room controller
(RXB) forwards a refrigeration request to the central
control unit (RMB) via refrigeration distribution zone 2.
Optimization of energy usage primary side
Heat distribution zone
The central control unit collects the heat requests,
evaluates them and forwards a heat request to heat
generation (RMH) via heat distribution zone 1.
Heat generation (RMH) provides heat only when at
least one of the consumers in the system calls for it
(demand-dependent control).
Refrigeration distribution zone
The central control unit collects the refrigeration re-
quests, evaluates them and forwards a refrigeration
request to refrigeration generation (RMS) via refrigera-
tion distribution zone 1.
Refrigeration generation provides chilled water only
when at least one of the consumers in the system
calls for it (demand-dependent control). In addition,
the production of chilled water is locked via the time
switch.

To enable the controller to give
consideration to refrigeration de-
mands, it must be internally con-
nected to function block ”Refrigera-
tion demand”
