Function
description
Description of functions
Synchronization of clock time
The clock time can be set on any of the Synco 700
controllers (RMH, RMU, RMS) and is synchronized
throughout the system.
Time switch
The time switch works autonomous because there are
no time switch slaves.
Outside temperature
Outside temperature zone
The ventilation controller (RMU) distributes the out-
side temperature in outside temperature zone 1. All
devices 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 ventilation controller
(RMU) forwards the heat request to the flow tempera-
ture controller (RMU, basic type C) via heat distribu-
tion 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 ventilation controller (RMU) 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)
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 calls for cooling, the
flow temperature controller (RMU, basic type C) for-
wards the refrigeration request to refrigeration genera-
tion (RMS) via refrigeration distribution zone 1, pro-
vided 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.
