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

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�

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

or humidity) or without sensor�
