Product Description
Sentinel Kinetic & Sentinel Kinetic Plus
The Vent-Axia Sentinel Kinetic & Sentinel Kinetic Plus 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 up to 90% of the heat into the
supply air entering the bedrooms and lounge.
In addition a Kinetic Plus unit is available that maintains a constant air flow independent of change in the system
pressure.
Figure 1: Sentinel Kinetic (Front of Unit as supplied) Figure 2: Sentinel Kinetic Plus (Front of Unit as supplied)
Sentinel Kinetic Summer By Pass Models.
The Sentinel Kinetic B, BH, Plus B , Plus BS, S BH, BS and Plus CVP 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 14 C (adjustable) in order to prevent
cold draughts.

Product Description
Sentinel Kinetic MVHR Operation & Monitoring 4
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

Defrost Active Screen
The Antifrost screen is only displayed if a summer
bypass is fitted. In installations where a negative
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.

Maintenance
Sentinel Kinetic MVHR Operation & Monitoring 16
4. Pull out the cell and make sure that the rear bottom
of the cell is securely resting on the lower edge of
the foam so you can access the rear pressure tube.
Repeat step 3 to detach the rear pressure tube.
When the rear pressure tube is removed then the
cell is free to clean.
Once the cell is cleaned then attach the
pressure tubes in reverse order starting from
