Description of functions
Synchronization of clock time
The clock time can be set on any of the Synco 700
controllers (RMH, RMU, RMS, RMB) and is synchro-
nized 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 the room controllers (RXB), the address to be
set for the time switch zone is the address of the time
switch master’s geographical zone.
Holidays / special days
Geographical zone
With the room controllers (RXB), it is not possible to set
a holidays / special day zone. This information is dis-
tributed 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 flow tempera
ture controller (RMU, basic type C) via heat distribu-
tion zone 2.
Refrigeration distribution zone
When the room calls for cooling, the room controller
(RXB) forwards a refrigeration request to the flow
temperature controller (RMU, basic type C) via refrig-
eration distribution zone 2.
Heating / cooling changeover
The flow temperature controller (RMU, basic type C)
transmits the heating / cooling changeover signal in
the heat and refrigeration distribution zone. This func-
tion must be activated via Extra configuration.
The room controller (RXB) decides whether the water
is suited for heating or cooling.
Optimization of energy usage primary side
Heat distribution zone
When flow temperature control (RMU, basic type C)
calls for heat, it forwards a heat request to heat gen-
eration (RMH) via heat distribution zone 1, provided
heating / cooling changeover demands heat.
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
When flow temperature control (RMU, basic type C)
calls for cooling, it forwards a refrigeration request to
refrigeration generation (RMS) via refrigeration distri-
bution zone 1, provided heating / cooling changeover
demands cooling.
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.
