General
Your Silavent 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 programmable user interface has been provided to help maintain a comfortable indoor
environment which includes the following features:
Time and date functions
Filter check reminder
Fingertip fan control; Low, Boost, Max
Automatic, summer heat exchanger-bypass operation
Automatic humidity level boost-switching
Your system may also have been wired to trigger Boost from a lighting circuit or a number of
lighting circuits.
The two 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.
AQH200-B and AQH240-B models are fitted with a fully automatic heat exchanger bypass
mechanism. The bypass will operate when the indoor target temperature reaches a pre-set value.
Using the digital user-interface, the trigger temperature for this operation can be set between
+15°C and 25°C.
Further details regarding your system are contained in the full installation manual which should
accompany this abridged householder guide.
