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.

Flow Rate settings
The Sentinel Kinetic Advance has four (4) user defined speeds in addition to the non-adjustable Maximum speed.
User defined speeds can be assigned a Mode name from the list below. (some options may not be available in your
region)
- Low
- Normal (Unit default operating mode)
- Boost
- Purge
- Holiday
- Night time
- Party
- Unoccupied
- Over pressure
- Fireplace
Note: The flow rate for each mode is set independently and not defined by the mode name.
When setting up Over Pressure or Fireplace Mode, the supply rate must be set higher than extract rate. This is to
provide a positive internal pressure in the dwelling to assist with the initial expulsion of combustion products from
the fireplace via the flue.
Fireplace mode does not prevent under-pressure
Mechanical Ventilation with Heat Recovery (MVHR) systems are not designed to provide combustion air.
NOTE: It is the responsibility of the open-flued appliance installer to ensure conformance with the current local
building regulations for fuel burning appliances.

Technical Data
Sentinel Kinetic Advance MVHR Installation & Commissioning Instructions PN 474957 9
Summer Bypass Mode
The Sentinel Kinetic Advance includes a Summer Bypass (SBP) feature to bypass the heat exchanger to
provide cooling when the desired Indoor Temperature is above the ambient temperature.
Note that the volume of air provided by a 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.
Modes of operation
Bypass Mode Operation
Off Bypass feature is disabled
Normal The unit will run on Normal Mode, unless cancelled
Evening Fresh The unit will run on the user selected Mode for 5-hours before
reverting to Normal, unless cancelled
Night Time Fresh*The unit will run at the user selected Mode, unless cancelled
Bypass mode will operate when both the Indoor and Outdoor temperature thresholds are exceeded, and the
outdoor temperature is below the indoor temperature.
Indoor Temp: This is the maximum desired indoor temperature. Above the set indoor temperature the
summer bypass will operate.
Indoor temp should be set, 2-3°C higher than the central heating thermostat to prevent the bypass operating
in winter, and 2-3°C lower than any air conditioning thermostat if fitted.
Outdoor Temp: This is the minimum allowed outdoor air temperature. The air temperature must be above
this value for the Bypass to operate, use this value to prevent the bypass operating in winter.
The suggested Outdoor Temp, is 14°C, set as appropriate for your region.
Bypass mode will be cancelled when either:
- The internal air temperature drops below the Indoor Temp threshold, or
- The external air temperature drops below the Outdoor Temp threshold
Note: Pressing the Boost button during Evening Fresh and Night Time fresh operation will revert the unit to
Normal bypass mode.
It is recommended that the user selected mode chosen for Evening Fresh and Night Time Fresh is higher
than Normal flow rate to reduce the indoor temperature more rapidly.
*Night Time Fresh Mode is intended for use 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 flowrate, ducting design, layout
and the size and type of vents used in the rooms. If improvements are required please contact your
installer.
