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.

Technical Specification

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.

User Menu Screens
From the Normal Airflow screen, press the button to access the rest of the User Menu screens.
Changing the value of a setting (if adjustable) is typically a 3-step procedure:
1. Press to select the setting (the setting will flash).
2. Use the or buttons to adjust the value. To scroll quickly, press and hold the or buttons for
more than 2 seconds.
3. Press again to enter the new settings and move to the next screen.
To return to the Normal Airflow screen, press the button repeatedly or press and hold the button for 5
seconds. Alternatively, the Normal Airflow screen will be restored if no buttons are pressed for two minutes
(timeout). Settings are stored in a the memory and will be retained in the event of mains power supply failure.
Low Airflow / Normal Airflow / Boost Airflow Screen
When the start-up screens are finished, the Low or
Normal screen is displayed showing operating status
(Low Airflow X % or Normal Airflow X % or Boost
Airflow X %).
The Normal screen displays the rate of normal airflow
(supply air) through the unit.
If the installation has proportional sensors or an internal
humidity sensor fitted, and any of these are boosting
the airflow, an αsymbol will be displayed.

An interval can be set, see page 40 of the Installation
and Commissioning manual, at which the unit reminds
the user to check the filters. This will be 6, 12 or 18
months. The normal screen top line will include Check
Filter as a reminder to check and, if necessary, clean or
replace the filters.
When this has been done, press and hold the and
buttons for 5 seconds to reset the automatic
message.
