Product Description
Sentinel Kinetic 200Z, 200ZH, 300ZH
The Vent-Axia Sentinel Kinetic 200Z, 200ZH, 300ZH Mechanical Ventilation / Heat Recovery (MVHR) is a
heat recovery unit designed for the energy efficient ventilation of houses and similar dwellings, conforming to
the latest requirements of the Building Regulations document F 2010.
The unit is 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 the heat into the supply air
entering the bedrooms and lounge.
Sentinel Kinetic 200Z, 200ZH, 300ZH Summer By Pass.
The Sentinel Kinetic units are fitted with a Summer By Pass (SBP) and will provide energy-free heating and
energy-free cooling when the house temperature and ambient temperature allows.
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.
If the room is cooler than the set ("indoor") temperature (i.e. you need the room heating) and the outdoor air is
warmer than the actual room temperature (i.e the outdoor air could heat your room) then the SBP will open and
the unit will supply warmer air to your room.
Note that the above only applies whilst the outdoor air temperature is above 14C (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

If the installation has switch sensors, is wired to the
lighting, has Vent-Wise sensors 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.

If running on boost due to pressing the button, a
device will ‘take over’ the boost. Flow will return to low /
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.

Purge Screen
Pressing and holding the button for 5 seconds
activates purge mode when you want to purge air from
the building. The unit will revert to normal flow by
pressing and holding the button again for 5

be triggered from the wireless transmitter/boost switch.
Purge mode runs the fans at full speed for 2 hours (120
minutes). The Purge screen displays a countdown of

is set to Off.
The Normal Airflow mode can be set to run during the
daytime i.e. from 6am to 11pm, the Low Airflow mode
will then run during the night from 11pm to 6pm.

Status Message Screens
The status message screens override the Normal Airflow and other user screens, and display status and key
operational conditions (temperatures or pressures, etc.) according to how the unit has been configured. If there
is more than one status item to be displayed, the highest priority message is shown.
These screens are displayed in a loop during normal operation of the unit, either after displaying the start-up
screens, or when commissioning has been completed. After a few seconds the display backlight is turned off in
order to minimise power consumption. The and buttons can be used to stop the loop sequence in order
to display individual screens for a longer period with the backlight turned on, if required.
Dryout Mode Screen
The Dryout Mode screen displays the time remaining
for the building to dry out. The unit runs at maximum
flow for 1 week.
Dryout Mode
168 h
Defrost Active Screen
The Defrost Active screen displays the status of the
defrost (antifrost) mode. If the external air drops below
0°C, to reduce the risk of frost forming in the heat
exchanger the defrost mode is activated. Defrost mode
can either alter the airflows or open the bypass and will
be pre-set by the commissioning engineer.
Defrost Active
Airflow Mode
Bottom line of display may be (Airflow Mode, 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 defrost mode will automatically activate.
This mode will open the bypass to prevent frost forming
on the heat exchanger.

Heating Failure 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
Restarting).

Maintenance
Caring for the Unit
Heat recovery units, by their very nature, require regular maintenance. The Sentinel Kinetic unit 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. Remove 2 filter cover plates and filters.
2. Clean gently by tapping or carefully using a vacuum cleaner if necessary.
3. Replace the filters and cover plates
4. Reset the automatic message, press and hold the and
buttons for 5 seconds.
12 Monthly Maintenance
Item Action
Fan Filters
(Interval to suit
environment)
Change the Fan Filters depending on which environment the unit has been installed; urban,
suburban or rural.
1. Remove 2 filter cover plates and filters.
2. Insert the replacement filters.
3. Replace the filters and cover plates.
4. Reset the automatic message, press and hold the and
buttons for 5 seconds.
Unit & Heat Exchanger
Cell Inspect and clean the unit: See the following pages
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.
