2.0 GENERAL DESCRIPTION
The HRX-aQ appliance is a key part of a whole house ventilation system
specifically designed to improve indoor air quality in dwellings. The
system is designed to provide measured amounts of filtered, fresh air to
living areas while constantly removing polluted, stale air from bathing,
cooking and washing areas at the same gentle rate. Any available heat
in the outgoing stale air is recovered by a built-in heat exchanger and
used to pre-warm the fresh supply air.
A manual boost switch is provided to increase the ventilation rate, e.g.
when cooking or showering thereby maintaining a comfortable indoor
environment.
A programmable user interface is provided to thereby maintaining a
comfortable indoor environment and includes the following features:
•
Time and date functions
•
Independent fan control adjustable at three levels; Low, Boost, Max
•
Programmable filter check reminder
•
Programmable 100% Thermal bypass
•
Optional 3 minute delay-on boost switching
•
Optional 5 to 30 minute delay-off boost switching
•
Optional programmable frost protection
•
Programmable humidity level boost switching
•
Temperature controlled switching available for optional duct heater
(supplied by others)
•
Elapsed runtime meter
The boost facility can also be triggered from a lighting circuit; contacts
to accommodate external sensors or switches are also available (Section
5.1).
The G3 filters in the appliance ensure that the fresh supply air is clean as
it enters the home. Additionally, the stale extract air is filtered to protect
the heat exchanger from unwanted contamination. These filters have
to be cleaned regularly, depending on the levels of pollution. The filters
should be replaced when they start to show visible signs of wear.
