2.0 Installation
2.1 Overview
2.1.1 The following instructions are intended to help prevent hazards. Installation should only be
carried out by a qualified electrician and competent persons in clean, dry conditions where
dust and humidity are at minimum levels
Note: we advise installers to fix all mains, switch and sensor wiring (in accordance with the
latest edition of the Wiring Regulations) prior to fixing the HRX-aQ unit in position
2.2 Preparation
2.2.1 When accepting delivery of the appliance, inspect for transit damage. If in doubt, call our
Customer Service Team on 03443 715523
2.2.2 The HRX-aQ appliance can be fitted directly to a concrete ceiling or suitable horizontal
timber support
2.2.3 Appropriate screw fixings to suit the support medium will need to be supplied by the
installer. The built-in mounts suit 4 x 4mm (No.8) pan head screws
2.2.4 Important: Ensure that there is sufficient space for access to the wiring centre (cover
removal), the condensation fittings and ductwork
2.2.5 Ensure that there is sufficient space below the appliance to access the filters and for
carrying out any future maintenance on the appliance
2.2.6 When viewed from below, the filter access and duct configuration is as shown on the
diagram below:

1.3 Main features
1.3.1 Thermal bypass
1.3.1.1 The AQH200-B and AQH240-B models are fitted with a fully automatic 100% heat
exchanger bypass mechanism. Time clock control and manual override are also
available
1.3.1.2 In automatic mode, the bypass will open when the indoor target temperature reaches a
pre-set value. Using the interface, the trigger temperature can be set between +15°C and
25°C
1.3.1.3 The interface contains an optional frost protection system. During periods of very cold
weather, the fresh air supply fan will automatically reduce in speed to approximately 20%
of its commissioned setting to reduce the load on your heating system and avoid
possible freezing of the heat exchanger. During these periods, the extract fan will
increase in speed to its commissioned boost speed to maintain an even air pressure.
Using the interface, the trigger temperature can be set between -15°C and +5°C

6.0 Maintenance
6.1 Routine maintenance
6.1.1 The two appliance G3 filters should be cleaned on a regular basis, the exact frequency will
be determined by individual living conditions.
6.1.2 The word ‘FILTER’ will appear on the home screen of the digital user-interface after the
set time has elapsed – when this occurs, clean the filters – see 5.1.4 for resetting details.
6.1.3 Before cleaning the filters, turn off the appliance at the isolator switch.
6.1.4 To remove the two filters, pull out the two caps from the front of the appliance and gently
slide out the filters in their carrier frames.
6.1.5 Lightly vacuum the filters to remove surface debris and then gently wash through in warm
soapy water. Ensure that the filters are completely dry before refitting. Important: do not
dry on a radiator or use excessive heat as this may distort the carrier frames.

1.1 Overview
1.1.1 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
1.1.2 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
1.1.3 The boost facility can also be triggered from a lighting circuit; contacts to accommodate
external sensors or switches are also available (see page 10)
1.1.4 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
1.1.5 This product is listed in the NCM PCDB, (was SAP Appendix Q) therefore, part of the
installation process requires that an installation checklist is completed and submitted to
the Building Control Body (BCB). Blank checklists are available at http://www.ncm-
pcdb.org.uk/sap/filelibrary/pdf/Check_Lists/Domestic_Ventilation_Compliance_Guide_201
0_-_Checklist_(extract).pdf
1.1.6 Pack includes:
•Domus HRX-aQ appliance
•Ventilation user-control centre
•4m length of 4 core signal cable (to connect AQH wiring centre and user-control)
•Installation and operating instructions manual
•Householders operating manual
•ErP label and data fiche
1.1.7 Ancillary items as required:
