MODE
BMS access: WR RD
Equipment function:

EASYLAB
–
FH, RR with RMFM, TAM with RMF

TROX UNIVERSAL
–
RE/RS with RMF, PR*/PD* with RMF
Function

FH: Operating mode default setting for a single fume
cupboard controller, only with individual operating
mode default setting (stand-alone operation)

RMF: Operating mode default setting for the entire
room
– The valid binding of the input variable results in a
valid operating mode default setting via BACnet
or Modbus
– The invalid binding or no setting does not lead to
any operating mode default setting in the con-
troller or room.
– Which operating mode is then used depends on
the default options available on the controller
Functional values (BACnet / Modbus)

1/0 = No default: The central BMS does not default
an operating mode for the controller or room.
The operating mode is set locally, e.g. on the room
control panel, on the fume cupboard control panel,
or using switch contacts.
If the operating mode is not set locally, the controller
activates standard mode.

2/1 = Standard mode: Normal operation in the day-
time (in Germany: usually according to DIN 1946,
part 7, 25 m³/h extract air per m² main useful floor
area)

3/2 = Reduced operation: Low mode in comparison
to standard mode, e.g. as a night-time setback

4/3 = Increased operation: High mode in compar-
ison to standard mode, e.g. in an emergency

5/4 = Shut-off: Shut-off of the volume flow controller,
e.g. to save energy at night or to shut down the
system

6/5 = OPEN position: Open position of the volume
flow controller

–
RE/RS with RMF, PR*/PD* with RMF
Function

Control input signal for shading, connected to the
controller or adapter module

Switch outputs DO5 and DO6 will be used

This BACnet or Modbus default overrides any other
defaults from the local room control panel
Data point

BACnet: Multistate Value Object – Instance 6
–
1 = No default
– 2 = Close blinds (activate switch output DO6)
– 3 = Open blinds (activate switch output DO5)

Modbus: Register 38
–
0 = Close blinds
– 1 = Open blinds
– 0xFF = No default

Unit/value range:

BACnet: Percentage value in increments of 0.5 %

Modbus: 0–200 (200 corresponds to 100 %)
Function

Signalling of an external volume flow rate shift, e.g.
for adjusting the room air change rate or for external
temperature control
 The shift signal is transferred as a percentage value
of a volume flow rate change range that has been
configured in the controller
Data point
 BACnet: Analog Value Object – Instance 19

Modbus: Register 9
