Siemens VAV modular controller ASV181.1E/3 CE1N3545en
Building Technologies 2019-03-21
With master/slave control, the DC 0/2…10 V output signal of the controller is fed
into the supply air volume controller (master controller) as the reference variable.
The extract air volume controller (slave controller) receives the master controller’s
actual value signal of the air volume flow as the reference variable (setpoint).
Minimum and maximum limitation of air volume flow
The limitation to
min
V

or
max
V

is made on the relevant controller. This means that
the OEM does not set these limit values on the VAV modular controllers. The
factory settings made by Siemens are 0 % and 100 % and will not be changed.
Here, a differentiation is to be made between two cases, which must be considered
when ordering the air volume controller with the OEM:
• The OEM sets the limit values (
min
V

and
max
V

) on the VAV modular controllers
• The limit values (
min
V

and
max
V

) are set on the assigned room temperature
controller, provided the controller used offers this facility
Disposal
The device is considered electrical and electronic equipment for disposal
in terms of the applicable European Directive and may not be disposed of
as domestic garbage.
• Dispose of the device through channels provided for this purpose.
• Comply with all local and currently applicable laws and regulations.
