Product Description
Sentinel Kinetic MVHR with Cooker Hood
The Vent-Axia Sentinel Kinetic Mechanical Ventilation Heat Recovery (MVHR) unit is a heat recovery unit
with a Cooker Hood designed for the energy efficient ventilation of houses and similar dwellings, conforming to
the latest requirements of the Building Regulations document F 2010.
In case of a fire or severe overheating on the hob, the unit is fitted with an intumescent fire damper to close the
duct as required by BRE Digest 398 and a thermal fuse to switch off the electrical power.
The unit is designed to be mounted in the kitchen above a cooker hob in a standard cupboard space for
continuous 24-hour exhaust ventilation of stale moist air from bathrooms, toilets and kitchens. The unit should
be switched to boost mode by extending the cooker hood during cooking, or by use of any of the standard
switches or sensors. As the stale air is extracted, a heat exchanger within the unit retains up to 90% of the heat
and transfers it to the supply air entering the bedrooms and lounge.

Models
441483, 441484, 441485, 441486 - Sentinel Kinetic with Cooker Hood and with summer bypass. An
internal damper is activated when the outside temperature is equal to, or greater than, the pre-set ‘Comfort
Temperature’ (adjustable between 16 and 30°C). The damper opens allowing cooler fresh air to bypass
the Heat Recovery Cell and reduce the internal temperature to the pre-set ‘Comfort Temperature’. When
the inside air temperature reaches the pre set ‘Comfort Temperature’ the bypass damper closes. (See
page 10 within the Operation & Monitoring leaflet for further information). Note that when the cooker hood
is extended the heat recovery cell bypass opens ensuring that grease and other contaminants from
cooking do not reduce its efficiency during normal use.
Accessories
441838 - Plug-in integral humidity sensor.
441865 - Wireless enable kit (consists of wireless receiver and one wireless switch).
437827 - Additional wireless switch (up to four may be connected).
441780 - Vent-wise accessory pack.
443131 – Wired remote control.
A range of sensors can be used to manage system demand and control the ventilation rate. These include an
internal humidity sensor, humidity sensors for independent mounting in rooms, wireless receiver and wireless
boost switches, CO2sensor, manual switches and pull cords. For these alternative control options, see
www.vent-axia.com
User Information
Operation of Cooker Hood
The unit is operated in boost mode when the telescopic hood is pulled out. Close it to return the unit to its

Appendix A: Options and Accessories
Humidistats
An optional internal humidistat is available as an accessory. (Part Number 441838). This adjusts the fan speed
proportionally depending on the temperature and relative humidity levels in the extracted air whilst avoiding
nuisance tripping at night time when temperatures drop and relative humidity naturally rises. The unit does not
just look for relative humidity levels above a set point, which can be unreliable in products that extract from
multiple rooms, but it also looks for a rapid increase in relative humidity typically generated by such activities as
showering or cooking.
For further details on options and accessories, refer to Sentinel Kinetic installation & commissioning
documentation.
