DVS G3 Instruction Manual

OPERATING GUIDELINES
DVS-G3® Reclaim System
Introd ction
Your G3 Reclaim system is the next generation whole house heat
exchange ventilation system. It is designed for the New Zealand
climate and is automated as far as practicable to allow for easy use
and operation to improve air uality, reduce moisture and reclaim
energy otherwise lost from your home.
When we install your G3 Reclaim we will tailor its settings to the size
and layout of your home so that it operates with optimum efficiency
with the fan speed calibrated for the size of your home. Note that both
fans run at the same speed irrespective of the number of supply and
exhaust diffusers so that the air through the heat exchange core is
matched.
There are two seasonal settings WINTER and SUMMER which you will
need to activate at the appropriate time (we have not automated this
because seasons are different throughout NZ and from year to year).
These Operating Guidelines explain how you can:
View the current status and settings of your G3 Reclaim system; and
Change and fine-tune your G3 Reclaim settings.
Along with this guide we have included information about changing your filters and some fre uently
asked uestions about the G3 Reclaim in the appendices to this guide. You will also find other
fre uently asked uestions about home ventilation in general in our booklet ‘General Guidelines and
Principles for All DVS ® Systems’.
Viewing Yo r C rrent Stat s and Settings
To view the status of your G3 Reclaim and its current settings go to the LCD touch screen control
panel and touch any part of the LCD screen.
This moves you from Screen-Saver mode to the Current Status screen, which will display the current
status of your G3 Reclaim as described below.
NOTE: Warning or Reminder Screens.
Your LCD screen will alternate between white and black and a warning or reminder will be shown
in faint text if:
The power to your G3 Reclaim system has been interrupted and the CLOCK needs to
be reset (see ‘Resetting or Changing Your Clock’ page 4);
Your air filter is due to be serviced (see ‘Changing Your Filter Service Reminder’ page
5 and Appendix 2);
In all cases the screen will flash once every 20-30 seconds. Touching the screen once will
activate the screen so you can read the message easily.

If a picture of a small child holding a stop sign is showing in the top right hand corner of the screen,
this indicates that the CHILD LOCK is on. You will need to deactivate the child lock before you can
proceed. To do this follow the steps set out in ‘Changing the Child Lock FUNCTION’ on page 3.
As noted above in certain circumstances your screen may be blank and alternating between white
and black. Touch the screen and a message will appear about either a power interruption, or to
remind you to change your filter.
The message for a power interruption will advise you to reset your clock and you will need to do this
before you can access the Current Status screen and operate your G3 Reclaim. Proceed to reset the
clock by following the steps in ‘Resetting or Changing your Clock’ on page 4.
The Current Status Screen shows icons and other information
summarising the current status and main settings of your G3
Reclaim system, in the example shown at right:
Roof-space temperature is 18º Celsius (the reading is
shown in the roof-space of the house diagram on the screen);
House temperature is 20º Celsius (the reading is shown
in the room space of the house diagram);
Current Status Screen
The day/time is Tuesday 08:37. The day and time
showing is the “system” clock time essential for controlling the
operation of timers in the system. It is a 24-hour clock.
The Fan symbol at top left showing ON indicates that the
fans are operating normally.
oIf the word BOOST and a time (half-hour, one hour, one and a half hours, or two
hours) is showing in the fan symbol, this indicates that the fans are operating at 200% speed for the
time shown;
oIf the word TIMER is showing in the fan symbol, this indicates that the timer is on
and the DVS® Reclaim will only start working according to the ON and OFF times set.
Season SUMMER is currently the season selected. The two seasons (‘winter’ and
‘summer’), set temperature will initially have been set by your DVS® installer. The temperature is the
same for both but will activate, if the temperature of the house is below that set in Summer and above
that set in Winter, by turning the exhaust fan off.
The MENU button is used to access one of the four operating menus. Pressing it will take
you to the MAIN MENU 1 screen, from which by pressing the MORE button you can access MAIN
MENU 2 and MAIN MENU 3. The four operating menus are accessed from the main menu screens.

Changing Yo r G3 Reclaim Settings
This section provides information on some desired changes and options available to fine tune your
system. Once you are more familiar with the contents of this section, you may find that the ‘ G3
Reclaim Quick Guide’ at Appendix 1 provides an easier guide for uickly navigating around the
system and its various menus.
Changing the Child Lock FUNCTION
When the Child Lock is enabled, access to the G3 Reclaim’s functions and menus is restricted,
eliminating the possibility of accidental changes being made to your system settings. When your
system is “locked” a small picture of a child holding a stop sign will appear in the top right corner of
the Current Status screen.
If the Child Lock is on, you will need to temporarily unlock the screen, before you can change any
settings, including the Child Lock.
To do so press the CHILD LOCK icon (top right hand corner) followed uickly by the bottom left hand
corner of the screen, and repeat until the Child Lock icon disappears. If this does not work at first,
keep trying but go faster.
With the Child Lock temporarily off, you can turn the Child Lock off permanently if you wish. You do
this by pressing the CHILD LOCK button until OFF appears (the CHILD LOCK button “toggles”
between on and off.). You reach this button by pressing MENU in the Current Status screen then
MORE on the MAIN MENU 1 screen to take you to MAIN MENU 2, then SYSTEM MENU.
When Child Lock is turned OFF, you or anyone else will be able to access all the menus and change
any setting by pressing the screen and menu buttons.
To turn the Child Lock ON, go to press MAIN MENU 2, SYSTEM MENU and press the CHILD LOCK
button until ON appears.
T rning yo r G3 Reclaim On and Off
Go to the POWER menu by pressing MENU on the Current Status Screen. This will take you to MAIN
MENU 1. Press POWER. This allows you to turn your whole G3 Reclaim system ON or OFF via the
MODE button, or to operate on pre-set TIMER settings via SET TIMER button.
MODE Selection
Press MODE to change the POWER setting to either:
ON (RECOMMENDED for normal use) The G3 Reclaim system will run continuously.
OFF (NOT RECOMMENDED for normal use.) The G3 Reclaim system will remain turned
off until ON or TIMER is selected.
SET TIMER (NOT RECOMMENDED for normal use.) The G3 Reclaim system turns on
and off according to times set.
3
NOTE: If you do not turn the Child Lock off permanently, it will automatically be activated when
you next return to the Current Status screen after making any changes, or after approximately 60
seconds of inactivity.
IMPORTANT SAFETY NOTE: Although the Air Handling Unit and other e uipment attached to
the G3 Reclaim may be switched off via the touch screen control panel or may have turned itself
off because of your timer selection, it is still connected to the house power supply. You MUST
disconnect electrical power to your G3 Reclaim by unplugging the Air Handling Unit’s 3-pin plug
before undertaking any servicing of your G3 Reclaim system. NOT RECOMMENDED. The Core
itself should only be opened by trained personnel.

Changing Airflow
The AIRFLOW menu enables you to adjust and fine-tune the airflow level higher or lower than the
pre-set calibrated level (represented by the ‘0’ setting).
Using the Up and DOWN Fan Controls
In MAIN MENU 1 press AIRFLOW to open the AIRFLOW MENU. To change airflow, press the UP or
DOWN arrows on the right hand side of the screen.
The AIR FLOW setting of ‘0’ is the calibrated and recommended level of airflow for your home.
Using Fan Boost
FAN BOOST changes the airflow to double the normal calibrated speed for a selected period of time.
Once the timer has expired the airflow will revert to the speed determined by the AIRFLOW menu and
the calibrated setting for your home. Pressing FAN BOOST cycles through 1/2HR, 1HR, 11/2HR or
2HR and OFF).
This option is useful for when you are taking a shower as it will enable the bathroom to be cleared
more uickly of the extra moisture created.
Changing Seasons
Changing Between Seasons
To change between SUMMER and WINTER touch the word shown on the Current Status Screen.
This automatically changes between Summer and Winter.
The only change that this makes to the system is to the logic within the algorithm used to determine
when the exhaust air stream fan is switched off. There will be circumstances when it is detrimental to
have the exhaust air passing through the exchange core and transferring its warmth to the incoming
supply air. The circumstances change from SUMMER to WINTER so it is important to change from
one season to the other at the appropriate time. When in SUMMER this will be when the incoming air
temperature is above that set. If in WINTER it will be when the incoming air temperature is below that
set.
Please do not hesitate to call our service staff on 0800 387 387 if you need help.
Resetting or Changing the Clock
As mentioned previously, a power interruption will cause the CLOCK to lose its settings. All other G3
Reclaim settings including any pre-set TIMER settings will be saved during a power interruption.
However, any TIMER settings will be inactive until the CLOCK has been reset.
The Clock will also need to be changed at the start and end of daylight savings.
Setting the Clock
It is important to check and set the CLOCK correctly as all TIMER settings rely on the correct day and time
being programmed.
Press the day/time figures on the Current Status screen or press the MENU and MORE buttons to
bring up the MAIN MENU 2 screen. Select SYSTEM menu and then press SET CLOCK.
4
NOTE: Increasing Airflow
You may wish to increase airflow in order to allow for a temporary increase in the number of
people living in your home, or to improve the extraction of stale air or moist air, for example
from your bathroom(s) – although FAN BOOST is the primary means to achieve the latter, see
below.
You can experiment using this feature, but if you consider a permanent increase or decrease in
the fan speeds is necessary, please contact DVS on 0800 387 387.

Select today’s day and time by pressing the DAY, HOUR and MIN buttons (to make them change
faster hold the button down). If you go past your desired day and/or time, just keep pressing the DAY,
HOUR and MIN buttons until the desired day and/or time re-appears. Press EXIT to finish.
Changing the Filter Service Reminder
The FILTER reminder screen will appear when the filter service timer has counted down to 0 months.
This is a reminder that your filters should be changed or serviced. We recommend changing your
filters approximately every 12 months. The filter reminder timer will have been set by our installer at
the time of installation.
We recommend that the G3 Reclaim is serviced annually to check the system, replace the filters and
clean the condensate drain. DVS has a Service Contract that can be ordered for this purpose. With
the Service Contract, there is no need to contact DVS as we will have a service technician call you to
book a time each year. Alternatively, you can contact DVS to book an annual service or order
replacement filters and undertake the work yourself. “Appendix 2” provides information on how to
change your filter.
Changing Screen Contrast
To Adjust the Screen Contrast for easier viewing if the LCD screen is too dark or light. Use the
MENU and MORE buttons to bring up the SYSTEM MENU then access and adjust the Screen
Contrast to best suit its position in your home and the surrounding conditions.
De-activating the Screen for Cleaning
To de-activate the touch screen for 30 seconds to allow the surface to be cleaned (with a soft dry
cloth), press and hold down the ‘387 387’ numbers at the bottom of the screen for 5 seconds until the
screen goes blank and a message “Touch screen disabled to allow cleaning” appears. After 30
seconds, the screen will return to the Current Status screen. Repeat if more time is needed to
complete cleaning. See Section below on Care of Your LCD screen

Care of Yo r G3 Reclaim LCD To ch Screen
The LCD touch screen is a sensitive piece of electronic e uipment. To get the best performance
and longest life possible from your screen please follow the guidelines below:
The display panel is made of glass. While the G3 Reclaim LCD Screen and Control
panel is uite robust, do not subject the screen to a mechanical shock by knocking or hitting the
surface, or pressing it with excessive force;
If the display panel is damaged and the li uid crystal substance leaks out, avoid getting
any in your mouth. In case of ingestion please contact the National Poison Centre 0800 764 766
(0800 POISON) for advice. If the substance contacts your skin or clothes, w ash it off using soap
and water;
Do not apply excessive force to the display surface of the LCD module when pressing
as it is soft and easily scratched;
Do not scratch the surface with a hard or sharp object;
DO NOT use any solvents to clean the screen as they may damage the polarised
surface of the glass. In particular do NOT use water, ketone or aromatic solvents under any
circumstances.
T
o clean the screen surface, first de-activate the touch screen for 30 seconds by pressing on the
387 387 phone number at the bottom of the screen and holding it down for 5 seconds.
Alternatively, if the CHILD LOCK is activated this will lock the screen. Then breathe on the face
plate and wipe it gently with any lint-free, soft, dry cloth or tissue to remove any dirt or smudges
from the screen.
NOTE: This is a 24 hour clock so please ensure that the correct time is set, e.g. 4.30pm should
be set as 16:30.
NOTE: Once you enter the FILTER menu, it will automatically re-set the due period to 12. Any
other time frame can be set by using the UP/DOWN arrows.

Filter Replacement Instr ctions
The G3 Reclaim has two filters as standard and a third filter if the optional Roof Vent is installed.
Customers may wish to avail themselves of DVS’s filter service or a DVS Service Contract to change
the filters and to carry out any maintenance or adjustments Please contact DVS on 0800-387-387 if
you would like DVS to do this for you.
Before going into the roof-space to change your G3 Reclaim filters:
Ensure that you have the 2 filters, (3 if you have roof vent fitted) a clean dry cloth, and a
good torch or safety lamp and some ducting tape,
Switch your G3 Reclaim system OFF at the control panel.
Read these instructions.
Carefully enter the roof-space. Take care not to stand on or trip over the G3 Reclaim ducting or
electrical cables connecting the G3 Reclaim Air Handling Units, the Reclaim core casing or any other
e uipment that may be connected to your system.
Locate where the filters are installed in the ducting by tracing the ducting before it enters the Reclaim
casing. This location will be after all the exhaust ducting comes to a common point and in the fresh air
intake for the supply air. The location will be identified by a metal tag sticking up above the white
insulated ducting. Remove the ducting from the end away from the casing by unwinding the black duct
tape. Reach inside the ducting and remove the filter from inside the metal tube and replace with the
new filter ensuring that the metal ring in the filter is pulled tight against the swage inside the filter tube.
Then re-tape the ducting to the filter tube,
Repeat for the other filter.
Note if you have a roof vent attached to your Reclaim there will be a third filter that needs replacing on
that as well. This is a standard filter that is attached via some plastic ties. These should be cut with a
pair of scissors and once the filter is replaced then retightened with the new cable ties which are
included with the filter. The cable ties should be joined together before putting around the filter and in
fact can be done before entering the roof space.
Remember to switch yo r G3 Reclaim back on at the control panel in yo r home.
You may also need to clean any dust from the ceiling outlet(s) and surrounding ceiling in the house
with a clean brush or dry cloth. Do NOT use a wet cloth.
Please note that in the vast majority of cases, dust around the ceiling diffuser is the result of dust
already inside the home being attracted by tiny electrostatic charges that build up on the surface of the
ceiling or diffuser as the incoming air brushes past these surfaces.
For Yo r Safety
Please take special care when climbing into your roof-space, and while in the roof-space walk only
on load-bearing roof beams or trusses. We suggest you ensure another person is in the house or
tell a neighbour you are climbing into your roof-space so that you can get assistance uickly if you
slip or have an accident.
Switch your DVS® OFF at the control panel - refer to Specific Operating Guidelines for your model of
DVS®.
Do NOT remove, open or attempt to service any DVS e uipment while it is connected to the house
power supply.

Appendix 3
Answers to Commonly Asked G3 Reclaim Q estions
Why can I hear an occasional beep’ from the LCD screen?
The G3 Reclaim will beep when touched and if any of its reminder alerts have been activated. There
are two reminder alerts programmed into the G3 Reclaim - the filter change reminder alert and the
power failure alert. If the filter change alert has activated, phone us on 0800 DVS DVS (0800 387
387) to organise a replacement. If the power failure alert has activated, all you need to do is reset the
clock. With the preset reminder alert you need to consider if it is time to change from Summer to
Winter or vice versa, based on current weather patterns. All other settings will revert to those in use
prior to the power failure.
Why does it beep’ when I press the touch screen, but nothing changes?
The screen will beep under very light contact but the touch mechanism will only activate under
moderate pressure. Try pressing slightly harder and also check that Child Lock is OFF.
When I use my touch screen, it makes a slight buzzing noise. Is this normal?
All LCD touch screens emit a faint ‘buzz’ when they are activated. This is normal and will stop when
the screen is no longer in use, and returns to Screen Saver mode.
How do I clean the LCD touch screen?
See ‘Care of Your G3 Reclaim LCD Touch Screen’ on page 6 of this Operating Guide.
