7.6 Control via BACnet
This example shows how to set a Hydro MPC to 50 % setpoint,
constant-pressure mode and bus control.
Before enabling control via BACnet, values for setpoint, control
mode and operating mode should be set.
• Enable bus control via the CU 351 display (settings/secondary
functions/control source, and select "controlled from bus").
• Set operating mode with Multistate output 1 (MO, 1). In this
example, the value for operating mode should be 1 (Start).
• Set control mode with Multistate output 0 (MO, 0). A value of 2
corresponds to Constant pressure.
• Set the setpoint to a value of 50 with Analog output 0 (AO, 0).
See section
7.2 Setpoint
for details on setpoint.
• To enable bus control via BACnet, set the Binary output 0
(BO, 0) to a value of 1.
Now the Hydro MPC should be running at 50 % in constant-
pressure mode with bus control.
7.7 Product simulation
Product profile simulation (booster simulation) can be useful for
testing and pre-commissioning purposes. It is possible to simulate
a booster profile when using a CIU 300 that is not connected to
any product. The CIU 300 will behave as if a booster was connected
on the GENIbus, even if that is not the case. The objects supported
by the simulated product will be available, although the data will
only be dummy values that do not simulate real booster behaviour.
Product simulation is enabled by setting the Multistate output
object "Product simulation" (MO, 2):

Note
Product simulation will always be disabled on
power-up.
Note
If a physical booster is detected on GENIbus at
power-up, it will not be possible to enable product
simulation.
