With certain dwellings the system may be configured to operate at what is known as a
“constant ventilation rate”. This means that there is no boost required to adequately
ventilate the home and the system operates at one set level at all times requiring no user
input/control.
8.1 Typical Automatic Control Options
Your system commissioning certificate completed by your system installer should detail
your automatic control options (if any).
Passive Infra-red (PIR) Sensors
These are motion sensing switches; these sensors trigger the system into boost mode
when activity/ motion is detected in a particular room. They are typically put into sanitary
accommodation or bathrooms.
Humidistat
These sensors detect humidity in the air and trigger the system into boost mode when
humidity reaches a certain level. These are typically placed in bathrooms or in kitchens.
Please note that the aircycle 4.1 system has an In-built humidistat that operates in the
same fashion.
Light switch
The lighting circuit of the home can be used to boost the system meaning that when the
occupier enters the room and turns the on the light, the system is triggered into boost
mode. This is typically used in sanitary accommodation and bathrooms. A double pole
switch should be used.
*The items detailed above are examples of the types of Automatic Control Options that
are typically used in conjunction with the Brookvent aircycle 4.1*
8.2 Typical Manual Control Options
Your system commissioning certificate completed by your system installer should
detail your manual control options (if any).
Spring loaded switch
This switch may be placed in any room within the house; however, it is typically used in
sanitary accommodation, bathrooms and or kitchens. When pressed, it will trigger the
system into purge mode for a defined time.
