General Guidance
Your system may be set up to boost from trickle speed automatically via sensors (e.g.
Passive Infrared Sensors) or manually via simple switch controls. These may be timed
switches or push/pull switches. Boost options, if provided and if required, should be used
when excess pollutants are being generated within the home (Cooking, Bathing etc.)
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 ade
quately
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 1.3 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. (note a double
pole light switch is required when used to operate the boost function).
*The items detailed above are examples of the types of Automatic Control Options that
are typically used in conjunction with the Brookvent aircycle 1.3*
