• The VRP-M system solution is not allowed be used for applications outside the specified field
of application, especially in aircraft or in any other airborne means of transport.
• Only components explicitly approved for this purpose by Belimo are allowed to be used for
the VRP-M system solution.
• The equipment configuration and settings form part of the unit manufacturer‘s system solu-
tion (OEM) and are not allowed to be modified without prior authorisation. All changes are
liable to disrupt operation and cause damage to the system or injury to persons!
• Attention must be paid to the following during the planning phase and before the VRP-M
system solution is operated:
– The compatibility of the VFP-.. sensor with the medium to be controlled must be verified,
– The specifications supplied by the VAV unit manufacturer (design, installation site) must
be consulted,
– All local regulations must be observed.
• Applications with fast-running actuator NMQB24-SRV-ST: The actuator moves into the
«CLOSED» position (left or right end stop, depending on the position of the direction of rota-
tion switch) when the supply voltage is switched on, in the event of a power failure >5 s or if
the pushbutton is actuated again. It then moves into the position required by the system. The
VRP-M control function is inoperative during this procedure.
• If the VRP solution is operated in a bus system, the cycle times of the MP-Bus and the
higher-level system must be taken into account.
• The manufacturer of the VAV unit (OEM) is responsible for ensuring that the VRP-M-system
solution is installed and set correctly as well as for the overall precision of the VAV unit.
If replacement devices are ordered, they are configured by the OEM at the factory according
to the installed system.
The VRP-M system solution is sold exclusively via the OEM channel for this reason.
System characteristics
Control characteristics
Adaptive, digital PID VAV controller (see «System components», page 3).
Pressure measurement
Static Belimo pressure sensors (see «System components», page 3).
Damper actuators
Belimo VAV damper actuators (see «System components», page 3).
Optimally matched components
In addition to standard VAV and CAV applications, the VRP-M system solution is also suitable for
fast-running applications such as those used in laboratories. The solution comprises optimally
matched, ready-to-connect components. These are only permitted for use in the controller-sen-
sor-actuator combinations specified by Belimo and selected by the unit manufacturer (see «Sys-
tem components», page 3).
VAV – variable air volume
Variable air volume applications based on a modulating reference signal, e.g. supplied by a DDC
controller, room temperature controller, EIB Konnex or LONWORKS
®
system.
The reference signal for the
min
...
max
working range can be set as follows:
DC 2 ... 10 V / DC 0 ... 10 V / adjustable DC range / bus operation
CAV – constant air volume
Constant air volume applications with operating steps (relays, switching contacts).
The following operating steps are available: CLOSED /
min
/
mid
/
max
/ OPEN / bus operation
Bus function
Up to eight Belimo MP devices (VRP-M / VAV-Compact / damper actuator / valve) can be con-
nected via the MP-Bus and integrated into the following systems:
– DDC controller with integrated MP-Bus protocol
– EIB Konnex system with Belimo UK24EIB interface
– LONWORKS
®
system with Belimo UK24LON interface

Diagnostics tool
VRP-M-Tool, plugged either directly onto the VRP-M VAV controller or via a terminal in the cont-
rol cabinet (connection 4 – PP/MP)
