Technical Data
Product Description
The Vent-Axia Sentinel Kinetic Advance models S & SX 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,
utility rooms and kitchens. As the stale air is extracted, a heat exchanger within the unit transfers up to
93% of the waste air’s room temperature, into the supply air entering the bedrooms and lounge. This
design concept provides significant energy recovery on household heat costs, coupled with the optimum
comfort conditions.
In addition, a Kinetic Advance SX unit maintains a constant airflow independent of change in system
pressure.

Sentinel Kinetic Advance Summer Bypass
The Sentinel Kinetic Advance includes a unique Summer Bypass (SBP) feature to 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.
Modes of operation
There are 4 Modes of Operation: Normal / Evening Fresh / Night Time Fresh and Off
Normal.
Airflow rate is determined by sensors, boost control and/or timed settings, otherwise it operates at 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 Fresh.
Intended for use as the outdoor temperature cools in the evening, but reverts to Normal mode after a set
time so that any increase in noise is avoided overnight.
The unit will go onto ‘Boost’ speed when the summer bypass opens and continue on this speed for five
hours If the external minimum temperature is reached before the end of the purge period, the unit will revert
to normal operating mode.
Air flow rate for ‘Boost’ speed is selected in the “GO TO MODE” screen
Night Time Fresh.
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.
The unit will go onto ‘Boost’ speed when the summer bypass opens and continue on this speed until the
external temperature is higher than the internal temperature and then revert to normal operating mode. If the
external minimum temperature is reached before the end of the purge period the unit will revert to normal
operating mode.
Air flow rate for ‘Boost’ speed is selected in the “GO TO MODE” screen.
Off
The summer bypass is switched off and will not provide energy free cooling.
Note: Pressing the Boost button during Evening Fresh and Night Time fresh modes will revert the unit to
normal bypass mode.
