L1020502 Quick start iAV control valve (Revision F | 25.10.2022)
01
Application
The iAV Control valve is an intelligent control valve that enables demand control to be set both centrally and zonally, in combination
with a pressure-controlled or non-pressure-controlled (roof) fan� This valve is therefore extremely suitable for ventilation projects
with collective exhaust, such as flats, student houses, studios��� as well as in utility construction (schools / offices / residential and
care centres)�
The iAV Control Valve is available with a built-in sensor (CO
2
or humidity) or without sensor�
01.A
Master / Slave
One or more iAV Control Valves can be provided per zone� These can function as master (stand alone) or as slave (with external
control)� An iAV Control Valve can be paired with an IQ unit or another master iAV Control Valve�
To control multiple iAV Control Valves simultaneously with one or more actuators (= zone with multiple valves), iAV Control Valves
can be added as a wireless (RF) slave under a master iAV Control Valve� If an iAV is added as a slave , it can no longer be paired as a
wired component with an IQ unit�
01.B
IQ unit
When using a pressure-controlled fan , the iAV Control Valve can operate independently� For a non-pressurised fan an IQ unit is
required that controls the fan with a PWM signal�
1
� For systems to be paired with a building management system (via ModBus), an
IQ unit must be provided, regardless of the fan type� Please refer to the manual of the IQ unit for more information�
01.C
Possible configurations
Depending on your situation, there are a few possible configurations:
Configuration A: one iAV Control valve per zone without IQ unit
This configuration is especially suitable for residential applications and rooms with small flow rates, in combination with a pres-
sure-controlled fan� All valves operate automatically based on measurements in the iAV itself or from an external component such
as a Room sensor� The valves operate independently of each other�

PWM = Pulse width modulation = pulses are emitted at a fixed frequency to control actuators, among other things
