USER GUIDE

WiFi connection indicator: This Indicates whether or
not you are connected to your home WiFi router.
24-hour clock: This is updated via the internet or
where you have no internet connection you are able to
manually adjust.
System settings
Day or Night: Near the top right of the screen is
a small Sun or Moon icon. There is an ability
in the DVS® to make the system behave dierently
depending on the time of day or night.
Note: Typically, this is not needed as the system
will self-adjust to the changes in day and night
temperature, humidity and CO2levels if needed. If you
would like to nd out more about this setting please
call us on 0800 387 387.
Fan: The fan icon near the top right of the screen will
rotate if the system fan(s) is rotating.
Note: if it is not rotating the system has stopped the
fan(s). This could be for a number of control logic
reasons and is nothing to be concerned about.
House: In the “roof space” section of the house you
can see the air supply temperature and humidity level
bar indicator. The “inside” section of the house shows
you the temperature and humidity level at the control
panel and also a bar indicating CO2levels in the home.
The humidity levels indicated are Absolute Humidity.
Your DVS® Premium
Connect system
represents the latest in
positive pressure home
ventilation technology.
The large easy to read
touch screen allows you
to see what Is happening
with your system and to
make adjustments if you
need to. The system Is
also able to be connected
to your home Internet

CO2levels
Note: The system is equipped with one CO2
sensor. A plug-in device which pairs with your
Connect control panel. If the CO2control function
is enabled (using the Settings menu) the system is
programmed to increase the ventilation rate when
the CO2level rises above 1000ppm. For specic
CO2level information see the graphs section of
the diagnostics menu. The system can be tted
with up to 4 of these remote sensors. When more
than one sensor is tted the system calculates the
average CO2concentration across the sensors.
Set Temperature and adjustment: To the right of
the house is an up arrow , a down arrow and a
temperature. The temperature displayed is the target
temperature the system will try to achieve when
the air supply temperature is able to help achieve it.
You can touch the and icons to adjust the set
temperature.

How to adjust or check on the operation
of your DVS®
Note: Most Customers nd they don’t need to make any
adjustments to their system. The system costs very little
to run and is programmed to give optimal ventilation
performance for your home whilst being as unobtrusive as
possible. However, if you need to make adjustments or to
check on what the system is doing, the instructions below are
a handy guide for you.
Turning the system ON or OFF
Touch the settings icon at the top right of the home
screen then – POWER OFF. The system is now OFF. To turn the
system ON – touch the screen. The system will re-start.
Set Temperature
Touch or
arrows to adjust. This is the temperature the
system will try to achieve.
Set and Forget or Customise: You can, for example set
this to 21oC. A typically ecient setting to provide good
'year-round' performance, or you can adjust seasonally if you
wish. In Summer, if you select a Set Temperature of 18oC for
example, the house will reach this temperature quickly. The
system will turn o, preventing warm air being introduced.
The system starts again when the air supply is cooler than
18oC. In Winter, you could select a higher Set Temperature of
23oC for example. When or if there is heat available from the
air supply, the system will be in Heat Recovery mode and will
try to reach 23oC in the home more quickly.
Note: The system will continue to operate even if the roof
space is cooler than the house. The system will automatically
reduce the air supply rate to the minimum normally needed
for a drier healthier home.
Help icon
Where applicable, the settings adjustment screens will
also contain a ?. If you touch that you will be given an
explanation of the nature of the settings and if applicable the
eect of adjusting them.
Fan Settings
Adjusting your fan settings increases or decreases the
level of ventilation or how aggressive your system is. Your
system has been programmed for your home. The DVS® will
typically perform well without the need to make fan settings
adjustments. However, you are of course able to make
adjustments.
Fan Boost
Touch settings icon then – SETTINGS > FAN SETTINGS >
FAN BOOST – Scroll up to set the time you wish to have fan
boost – OK > EXIT > EXIT
The system will be in fan boost mode and will return to
normal after the selected time.
Fan Speed programming adjustment
Touch settings icon then – SETTINGS > FAN SETTINGS >
FAN CONTROL – Slide the Fan Speed bar up (to the right) or
down (to the left) – OK > EXIT > EXIT
This setting changes the programmed minimum condensation
control fan speed for your system. Heat recovery and heat
retention fan settings are indexed to this speed and so will
increase or decrease the fan speed relative to this setting.
Heat Recovery settings
Touch settings icon then – SETTINGS > FAN SETTINGS >
FAN CONTROL – Slide the Heat Recovery bar up (to the right)
or down (to the left) – OK > EXIT > EXIT
This setting adjusts how aggressively the system reacts
when the air supply being introduced is warmer than the air
temperature (measured at the control panel) in the home.
Heat Retention settings
If you experience cooling from the system, this feature can
help. We suggest making small changes, then assessing the
need to increase it.
Touch settings icon then – SETTINGS > FAN SETTINGS >
FAN CONTROL – Slide the Heat Retention bar up (to the right)
or down (to the left) – OK > EXIT > EXIT
This setting adjusts how passively the system behaves
when the air supply being introduced is colder than the air
temperature (measured at the control panel) in the home.
Note: if you have Heat Retention activated the system will
reduce air supply to below the programmed minimum. This
can aect the performance of the system and so you may
see more condensation or dampness on cooler days than the
DVS® would normally allow.
For further assistance please call DVS®on 0800 387 387 3

Humidity Settings
For adjusting the sensitivity of the system to an
air supply which is more humid than the air inside
the home. A higher setting will mean the system
reacts more quickly to a humid air supply then
remains o for a period of time and until the air
supply is dry enough to continue ventilating your
home. The DVS® technician sets this function
when the system is installed, however, this
setting can be increased or decreased.
Note: To prevent nuisance stopping and starting
(oversensitivity) the DVS® is programmed to
allow some minor higher air supply humidity
readings before it will stop ventilating. Please call
DVS® on 0800 387 387 if you need assistance
and before you adjust these settings.
Humidity settings
Touch settings icon then – SETTINGS >
HUMIDITY CONTROL – Scroll the Humidity
sensitivity or Humidity time up or down to the
level you wish - OK > EXIT
CO2Sensing & Control
For enabling or disabling the CO2control function. The DVS®
technician enables this function and pairs the sensor(s) when the
system is installed, however, this function can be Enabled (turned
on) or Disabled (Turned o).
CO2Enable / Disable
Touch settings icon then – SETTINGS > CO2CONTROL > ENABLE
(touch the Enable/Disable slide switch icon to change to Enable or
Disable) - OK > EXIT
CO2Sensors - connecting to the system
The DVS® Connect range has one remote plug in CO2sensor as a
standard inclusion. Extra sensors can be tted with a maximum
of four sensors per system. When multiple sensors are tted the
system uses the average CO2reading across all sensors to activate
a higher ventilation rate when the average CO2concentration rises
above 1000ppm.
Connecting to the system
Plug in the CO2sensor in your room of choice and turn on the switch
on the plug so the sensor has power to it (leave the sensor plugged
in and turned on at all times) – Go to the control panel and touch
the settings icon then – UTILITIES > MANAGE CO2> ADD SENSOR
– Go back to the sensor, hold in (you will need to use a toothpick,
matchstick, sharpened pencil or similar) the recessed button on the
sensor for 5 seconds until the green light emitting from the bottom
of the sensor holds solid (this starts the pairing process) – Go back to
the control panel and when the pairing is complete - EXIT > EXIT
If the system did not have a CO2sensor connected previously you
will notice a new bar appears on the home screen. This is the CO2
level indicator mentioned above in the “On your home screen”
section.
WiFi connection and software upgrades
To check for upgrades or reconnect to your WiFi
Touch the WiFi icon then choose – WiFi Scan or Check for upgrades (whichever is applicable) – then follow the instructions.

Some guidance on optional feature settings
The system will give you the ability to control the optional
feature(s). These can include running the feature for a
short period of time as and when you need to. This is called
a Manual option. Alternatively, you may wish to run the
optional feature(s) at a set time every day or night. This is
called a Timer option. If you select this control option, you
will then be asked to set up the timer appropriately. There
is also the ability to activate the optional feature(s) using
temperature as the activation method. If you choose that
option, you will then be asked to set the temperature and

System Performance
Your DVS® will help to provide a healthier, drier living
environment.
Ventilation, heating (in cooler months) and cooling (in
warmer months) are all keys to providing a drier, healthier
and more comfortable living environment.
Winter (or cooler months)
Your DVS® is programmed to supply enough ventilation for
your home based on the size of your home. If the home is
now drier, you may wish to reduce the level of ventilation
using the Fan Speed adjustment. The ideal being to
have the minimum level of ventilation while retaining a
drier, healthier home. If the home is not yet drier, you can
increase the Fan Speed adjustment to ventilate at a higher
level.
Summer (or warmer months)
Experience has found increasing the Fan Speed setting to
higher levels provides better ventilation in warmer months.
Note: If you feel you have DVS® system performance
issues, turn the system o and call 0800 387 387 so that
we can assist with this issue.
Filter(s)
Maintenance of the equipment, including replacement of
the air lter(s) with genuine DVS® lter(s), is required to
