Product Description
Sentinel Kinetic Sentinel Kinetic F Sentinel Kinetic Plus & Sentinel Kinetic High Flow
The Vent-Axia Sentinel Kinetic, Sentinel Kinetic F, Sentinel Kinetic Plus & Sentinel Kinetic High Flow
Mechanical Ventilation/Heat Recovery (MVHR) are heat recovery units designed for the energy efficient
ventilation of houses and similar dwellings, conforming to the latest requirements of the Building Regulations
document F 2010.
The units are designed for continuous 24 hour exhaust ventilation of stale moist air from bathrooms, toilets and
kitchens. As the stale air is extracted, a heat exchanger within the unit transfers up to 90% of the heat into the
supply air entering the bedrooms and lounge.

Sentinel Kinetic Range Summer By Pass Models.
The Sentinel Kinetic B, BH, FH, Plus B, Plus BH and High Flow are fitted with a Summer By Pass (SBP) and will
provide energy-free cooling when the house temperature and ambient temperature allows.
Note that the volume of air provided by this ventilation system is a fraction of that required for space heating or
space cooling and will not in itself be sufficient to cool a room. It will however, provide a contribution and make a
difference.
There are three operating modes, Normal, Evening Purge and Night-time purge.
Normal Mode.
Air flow rate is determined by sensors, boost and timing settings, otherwise is normal rate.
If the room is warmer than the set (shown as "indoor") temperature (i.e. you need the room to be cooler) and the
outdoor air is cooler than the actual room temperature (i.e. the outdoor air could cool your room) then the SBP will
open and the unit will supply cooler air to your room.
Note that the above only applies whilst the outdoor air temperature is above 14 C (adjustable) in order to prevent
cold draughts.
The set ("indoor") temperature should be set 2 or 3 degrees higher than the central heating thermostat and 2 or 3
degrees below any air conditioning thermostat if fitted. This will prevent any clash between the separate systems.
Evening purge Mode.
Intended for use as the outdoor temperature cools in the evening, but reverts to normal control after a set time so
that any increase in noise is avoided overnight.
Air flow rate is always at boost.
The bypass closes and the purge stops if the temperature conditions described in Standard Mode are no longer
met or 5 hours after the bypass opened.
Night-time purge Mode.
Intended for use as the outdoor temperature cools in the evening and continues through the night when cooling is
a higher priority than any increase of noise. Note that the air noise in your system is influenced by the ducting
design and layout and the size and type of vents used in the rooms. If improvements are required speak to your
installer.
Air flow rate is boost.
The bypass closes and the purge stops if the temperature conditions described in Standard Mode are no longer
met.

Defrost Active Screen
The Antifrost screen is only displayed if a summer

pressure is not permitted during antifrost operation, set
this to bypass mode.
Available options: Airflow Mode (default) and Bypass
Mode.
Airflow Mode - When the supply air temperature is
between 0° and -20°C, antifrost will automatically
activate. This will reduce the supply airflow rate and
increase the extract airflow rate to prevent frost forming
on the heat exchanger. During antifrost operation the
supply motor can stop for 15 minutes and run for 45,
depending on the temperature below 0°C. If the supply
air temperature is -20°C or below the supply fan
switches off and the extract fan continues to run at
reduced rate to prevent frost forming on the heat
exchanger.
Bypass Mode - While the supply air temperature is
below 0°C, the antifrost mode will automatically
activate. This mode will open the bypass to prevent
frost forming on the heat exchanger.

Room Too Cold Screen
The Room Too Cold screen displays the status of the
fan. If the heating system in the building fails or is
switched off and the internal temperature drops below
5°C, the unit will stop running so as to not bring cold air
into an already cold house. The unit will start up every
hour and will run for a short time to measure the
temperature of the property. When the temperature
rises, e.g. the heating system is switched back on, the
unit will restart and continue normal operation.
Bottom line of display may be ( Fan Off, Fan

Maintenance
Caring for the Unit
Heat recovery units, by their very nature, require regular maintenance. The Sentinel Kinetic has been designed
to facilitate access to enable maintenance to be carried out easily.
Filter Maintenance
Item
Action
Fan Filters
When the unit displays “Check filters”. This is a reminder to ensure that the filters are not so
dirty that they are blocking the airflow or allowing dirt to pass through. The rate at which the
filters become dirty will vary hugely depending on the environment and the activity within the
property.
1. Open the filter flaps and remove the 2 filters.
2. Clean gently by tapping or carefully using a vacuum cleaner if necessary.
3. Replace the filters
4. Close the filter flaps.
5. To Reset the filter service time:-
i) press and hold both the and buttons for 5 seconds until “Reset Filter?” is shown.
ii) Press to confirm reset “Filter Reset” will be shown.
Periodic Maintenance

2. Insert the replacement filters.
3. Close the filter flaps.
4. To Reset the filter service time:-
i) press and hold both the and buttons for 5 seconds until “Reset Filter?” is shown.
ii) Press to confirm reset “Filter Reset” will be shown.
Unit & Heat Exchanger
Cell
Inspect and clean the unit
1. Isolate the mains power supply.
2. Remove front cover from the unit.
3. Remove the 2 filters.
4. Slide out the heat exchanger.
5. Wash the outer cover and heat exchanger in warm water using a mild detergent and dry
thoroughly.
NOTE: Keep water away from all electrical components and wiring within the unit.
Motors
Inspect the motors for build-up of dust and dirt on the impeller blades, which could cause
imbalance and increased noise levels. Vacuum or clean if necessary.
Condensate Drain
Check the condensate drain tube is secure and clear of debris. Clean if necessary.
Fastenings
Check that all unit and wall-mount fastenings are sufficiently tight and have not become
loose. Re-tighten if necessary.

Overview
The functional differences described in this Appendix are available when Control Mode 02 is selected from the start-up
screens. Control Mode 02 assigns alternative functions to certain wiring Terminal Connections (described in Appendix
One of the Installation and Commissioning Manual) and allows additional airflow settings to be accessed via the
button on the front of the Kinetic unit or remote control as shown below:

If the wireless boost option is fitted, this can be triggered from the wireless transmitter/boost switch.
If the installation has switch sensors, is wired to the lighting, has Vent-Wise sensors, Vent-Wise momentary switch or if
the internal time switch is set for periodic operation, operation will change from normal to boost automatically. Pressing
the button will reveal a code to show which device has activated boost.
s4 = Switch SW4
ls = Switched live (LS)
w1-4 = Wireless controller
c1-3 = Internal Time switch
If running on boost due to pressing the button, another device may ‘take over’ the boost. Flow will return to normal
when that device switches off. If a number of different devices are calling for boost flow, the unit will run at boost until the
last one has reverted to normal.
