Sentinel Kinetic Range Summer By Pass Models.
The Sentinel Kinetic B, BH, Plus B, Plus BS, S BH, 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.
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.

Installation
Overview
The following instructions are intended to help prevent potential hazards and installation should only be carried
out by a qualified electrician and installer. This booklet covers both the Kinetic and Kinetic Plus. The control
systems are identical on all units. There are some differences during the physical installation that the installer
needs to be aware of.
NOTE: we advise installers to fix all mains and sensor wiring along with any internal accessories prior
to fixing the MVHR unit in position, leaving approximately 500 mm tails to allow for internal routing.
Before Installation of the Unit
Inspect the Unit
When taking delivery of the unit, check the items delivered against the enclosed delivery note. Inspect the unit
for damage in transit. If in doubt, contact Customer Services. Each box contains a Kinetic HR unit and an
accessory pack containing wall brackets, condensate drain link pipe, worm-drive clip, fixings and product
documentation.
Lift and Move the Unit Safely
On page 5 check the weight of the unit that you are installing. Always use appropriate lifting techniques and
appliances when moving heavy equipment.
Check Site Requirements and Safety Notices
Check that the physical and environmental conditions for the site meet, or exceed, the requirements detailed in
the Technical Specification on page 5.
Read and observe the safety notices listed in Warnings and Safety Information on page 2.
Unit Installation
The Sentinel Kinetic unit is typically installed on a wall in a kitchen, storage cupboard, roof void, or similar. It will
fit in a 600 mm (external) x 300 mm deep (internal) kitchen wall cupboard.
The Sentinel Kinetic Plus unit is typically installed on a wall in a utility room, storage cupboard, roof void, or
similar.
The wall should have sufficient strength to support the unit.
Take into consideration the position of the electrical services and the condensate drain.
Ensure there is adequate access for installation, operation and maintenance.
It is recommended that a local disconnection mains and sensor terminal box is installed within 1m of the unit to
facilitate future maintenance.
The unit MUST always be mounted vertically with ducting exiting vertically or horizontally. Do not use this unit
as a support for any other equipment.
Select Unit Orientation
The unit is supplied from the factory with the condensate exit (and the atmosphere spigots) to the right of the
unit, when viewed from the front. Access is required to the Control Unit on the front of the unit in order to
commission, operate and maintain the unit. If the unit is to be installed as supplied, skip the following section
and go to Vertical Discharge Condensate Installation on page 13.
Sentinel Kinetic MVHR Installation & Commissioning 10
Page 11
Installation
If the orientation of the condensate exit (and the atmosphere spigots) would be better suited on the left of the
unit, the front Control Unit and the rear Cable Inlet Plate can be swapped over to allow the unit to be installed in
the opposite orientation.
Sentinel Kinetic Plus CVP is supplied with condensate drain exit to the right of the unit and cannot be installed in
the opposite orientation (LH).
Installing the Unit in the Opposite Orientation (LH Condensate)
This procedure for opposite orientation applies to all
Sentinel Kinetic range named in this document,
except Kinetic Plus CVP.
Installing the unit in the opposite orientation involves
removing the front cover (and associated Control Unit
Panel), and the rear cover (and associated Cable
Inlet Plate), rotating the unit chassis and covers
through 180 degrees and then re-attaching them.
This moves the condensate drain exit from the right
(rear) corner of the unit to the left (front) corner of the
unit, when viewed from the front (viewing the Control
Unit).
The arrow labels on the top edge of the Covers
should be correctly matched to the arrow labels on
the top of the Case.

Electrical Installation
Connect Switches and Sensors
The unit can be switched to boost by a variety of methods:
Applying 240 V to the LS input .
Switching across 1 of 5 pairs of switch terminals.
Applying between 0 and 10 V as a proportional input to two input terminals.
N.B Alternative functions are assigned to SW/1, SW/2, SW/3 & SW/5 when Control Mode 02 is selected in
the start-up screens see Appendix One for further details.
In addition, fitting a Vent-Wise Accessory to the unit means that switch terminals 1-3 can be connected to be
switched by a current detector (for example, detecting a hob being switched on) or a temperature sensor (for
example, detecting the flow of hot water). Terminal 4 can be used in conjunction with a momentary switch or
switches.
Connect any switches or sensors required to control the unit by connecting to the terminal connectors at the
bottom of the control unit as shown below and in Table 1. If necessary contact Vent-Axia regarding the wiring
and fixing of accessories and sensors.
The cable entry back plate may have grommets or easy knock-out positions. If the knock-outs are used then
ensure that you use a grommet or gland to protect against potential water ingress.
When fitting external controls the appropriate cord anchorage and glands, according to country
requirements for cable size should be fitted, these glands should have a minimum water ingress
protection of IPX2.

WARNINGS
1. MAINS SUPPLY VOLTAGES (220-240 V AC) ARE PRESENT IN THIS EQUIPMENT WHICH MAY CAUSE
DEATH OR SERIOUS INJURY BY ELECTRIC SHOCK. ONLY A QUALIFIED ELECTRICIAN OR INSTALLER
SHOULD CONNECT THE POWER SUPPLY TO THIS UNIT.
2. THIS UNIT MUST BE CORRECTLY EARTHED.
This unit is designed for operation from a single-phase alternating current source (220-240 V AC). A 1.5 m cable
is connected internally to the unit for connection to a switched fused spur.
To connect the power supply:
1. Ensure the local AC power supply is switched off.
One end of the power cable supplied is already connected to the unit and routed through the Cable Inlet
Plate via a suitable gland to ensure the IP rating of the unit is not affected.
Connect the other end of the cable to the switched fused spur.
Use cable clamps and clips to secure the cable, as appropriate.

Installation
Connecting a Boost (Light) Switch
A Switched Live (LS) may be used to boost the airflow when a light is turned on, for instance in a bathroom or
kitchen. If the LS core of the mains cable is not used it should be terminated in an appropriate manner.
Power supplied to the unit via a 3 pole isolating switch must be supplied via the same circuit as the LS
connection. Alternatively an isolator relay controller, part number 442030, may be used.

Vent-Wise Screens
These screens are only displayed if a Vent-Wise Card is fitted. Replacing J4 3-4 link with a Vent-Wise board
converts S/W1, S/W2 and S/W3 from switch inputs to Vent-Wise inputs. In addition SW4 can be used by a
momentary switch.
Vent-Wise sensors measure current or temperature. When the current or temperature exceeds a ‘trip’ level,
boost airflow is selected. Low / Normal airflow is resumed after a timed delay once the current or temperature
has dropped below the trip level.
Any of the sensor types can be connected to S/W1, S/W2 or S/W3 but once the Vent-Wise Card is fitted,
ordinary switches must not be used.
In use, the Vent-Wise Card with three sensors will run hot to the touch albeit well below its maximum
temperature. If any input is shorted (e.g. used with switch), the board will overheat and shut down.
Nominal trip level is with the Load Pot set to (60 %). A temperature sensor will trip with hot water at around 40ºC
and a current one around 1.5 A. Time Pot setting is from 1 to 25 minutes with a default of 20 minutes.
A one-second push on a momentary switch wired to SW4 will run boost for up to 25 minutes. The overrun timer
can be set from 15 to 30 mins. A second one-second push will cancel the boost as would a “cancel boost”

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
step 4 to 1. Do not over tighten the screws for
securing clips. The clips should just slightly
grip the rubber grommet strips as over
tightening of the clips can block the air
pressure.
Sentinel Kinetic Plus CVP Control, Microbore tube connection to PCB
Sentinel Kinetic Plus CVP control PCB includes two
pressure sensors with Microbore tubes (pressure tubes)
connected to them. A pressure port identification label is
used adjacent to the pressure sensors with dots and
numbers 1 to 4 representing the pressure ports and
labels 1 to 4 on the Microbore tubes.
Note:
Wrong connection of the Microbore tubes will cause
failure in constant volume operation.

Room Too Cold Screen
The Room Too Cold screen displays the status of the
fan. If the heating system in the building fails or is
switched off and the internal temperature drops below
5°C, the unit will stop running so as to not bring cold air
into an already cold house. The unit will start up every
hour and will run for a short time to measure the
temperature of the property. When the temperature
rises, e.g. the heating system is switched back on, the
unit will restart and continue normal operation.
Bottom line of display may be ( Fan Off, Fan

Note: Access to the commissioning screens is prevented if the display shows Antifrost Active, Room
Too Cold or a Fault Code. In this event, switch the unit off and on again and enter the commissioning
screens within one minute. If you are within the commissioning screens the Antifrost and Room Too
Cold Failures modes will not operate allowing the flow rates to be adjusted even in a property which is
below 5C.

Appendix Two
Appendix Two: Options and Accessories
CO2 Sensor
An optional wall-mounted CO2 Sensor (433257) may be used to control airflow. The CO2 sensor measures the
CO
level in ppm (parts per million) and the unit adjusts the fan speed accordingly. When the CO2 level is below
2
the lower threshold (adjustable), the fan will run at Normal speed. When the CO
threshold (also adjustable), the fan will run at Boost speed. If the CO
thresholds, the fan will run at a speed between Normal and Boost proportional to the difference between the
CO
level and the thresholds.
2
Normal / Boost Switch
An optional Normal/Boost Switch (455213) may be used to control airflow. Connecting a switch will enable a
manual control to be used in conjunction with other boost controls.
Humidistats
An internal Relative Humidity Sensor PCB (441838) may be used to control airflow. The unit 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 rapid increase in relative humidity typically generated by such activities
as showering or cooking.

Connecting a System Cooker Hood
A system cooker hood that has a Switched Live output to trigger the unit from normal to cooker hood boost can
be connected as follows. The cooker hood must be double insulated.
1. Remove a blind grommet from the Cable Inlet plate
and insert the 3 core cable from Cooker hood.
2. Connect the 3 wires to the terminal block
marked J12
Brown = L
Grey = N
Black = LS
Connecting an opto-coupler (447340)
The LED terminals are intended to drive a remote LED to indicate that a fault has occurred. They provide a 5 V
LED driving signal output between the + and – terminals that enables remote indication of a unit fault. See the
Control Panel for fault code (Refer to installation and commissioning guide listed above). This signal could also
be used by a BMS system so that it is informed that a fault has occurred. If a volt-free contact is required then
use this opto-coupler to provide electrical separation.
Connect the flying leads of the opto-coupler pcb into the LED terminals, + to + and - to Connect the pair of leads from the BMS to the terminal block of the opto-coupler pcb. Polarity does not matter
here.

3. Ensure that the system address, set by the 6-way DIP switch on the Wireless Switch PCB matches that on
the Wireless Receiver PCB. For multiple systems in close proximity to each other, the system addresses
need to be different. The Wireless Switch PCBs also have a 2-way DIP switch to set the transmitter address.
Up to four Wireless Switch’s can be used to control any one unit. The Wireless Switch address needs to be
different for each Switch in a system.
