1. Sygnal Connect Operation
Your Sygnal Connect control system coordinates the operation of the Sygnal indoor and outdoor units and
zone dampers to provide the finest indoor climate control solution currently available.
The system features variable refrigeration and airflow (VRAF) and multi-zone variable air volume (VAV)
capacity modulation to ensure the appropriate amount of heating or cooling capacity is distributed to each
area.
Individual temperature sensors located in the touchpad for each VAV zone detect subtle temperature
variations and the system responds by increasing or decreasing the amount of air to each area to maintain the
required comfort level.
While this is occurring the VRAF capacity matching system monitors the requirements of the space as a whole
and increases or decreases the conditioning output from the compressor and the speed of the indoor fan to
suite.
Timer programs allow you to schedule the start and stop time for the entire system and individual zone on and
off times to suit your needs.
To turn on your system simply press at any touchpad. In the default auto mode the system will begin
heating or cooling as required. When all areas are off the conditioning system shuts down.
Please read on for more information about controlling your indoor environment.

4. Manufacturers Recommendations
The following information is a guide to efficient use of your new Sygnal system. Following these tips will
contribute to the long life of the unit and could save you money.
4.1 Essential Operating Guidelines
The Filters must be in place to run the unit. Never operate the unit without the filters.
4.2 Tips for saving energy
For optimum unit efficiency, cost benefit and comfort levels we recommend setting the temperature
between 20°C and 24°C for both heating and cooling.
By covering windows with blinds or curtains you increase the cooling (heating) efficiency.
Dirty air filters cause inefficient operation and reduce unit efficiency. Clean monthly by either vacuum
or hand wash in mild detergent.
Turn the system off at the circuit breaker (located near the outdoor unit) prior to going on holidays to
ensure timer programs don’t cause unnecessary operation.
4.3 Power Failures
Your new Sygnal system has a memory function that automatically stores settings in the event of a power
failure. After power is restored the unit will automatically re-start with the same settings active before the
power failure and in accordance with any timer setting. This feature covers all operating settings.
5. Maintenance
Regular maintenance will ensure your Sygnal system operates at maximum efficiency.
5.1 Return Air filter cleaning
Cleaning the filter in the return air grille is recommended every month. Filters may be cleaned by either
vacuum or hand wash in mild detergent. Never operate the air conditioner without the filter. Ensure the filter
is in good condition, if not contact your installer for a replacement filter (a charge will apply)
5.2 Outdoor Unit
Do not place any object in front of the condenser. Keep free of grass, leaves and any other form of debris. This
will allow for proper air flow and ensure unit efficiency.
5.3 Vents & Return Air Grill
Regular cleaning of the return air grill and air vents is recommended. This will prevent build-up of dust and
dirt.
5.4 Controller
Clean the wall control with a dry cloth. Do not use a spray detergent or water.
The control circuits for the indoor and outdoor units carry voltages > 240 VAC which can cause serious injury or death.

Air Conditioner has restarted but does not operate
for 4 minutes
The normal operating behaviour to protect the
compressor. Wait until the air conditioner begins
operating.
Operation stops for up to 12 minutes during heating
and a different noise/sound comes from the unit.
The unit has entered defrost mode to melt the frost
which has accumulated on the outdoor unit. This
will take no longer than about 12 minutes so wait
for the unit to resume normal operation. (Frost
accumulates on the outdoor unit when the outdoor
temperature is low and the humidity is high. Water
comes out from the outdoor unit).
The air conditioner does not operate.
Has the mode been set correctly?
Is at least one zone ON.
Has the setpoint for ON zones been set low enough
for cooling or high enough for heating?
Has the circuit breaker been tripped?
The air conditioner does not cool/heat effectively.
Has the mode been set correctly?
Are all the windows and doors closed?
Are the filters dirty?
Are the intake or outlet vents of the outdoor unit
obstructed?
The outside temperature maybe below or above
design conditions. Turning OFF any zones not
required may help.
Abnormal noise is heard during operation (except
during the defrosting operation).
Water leaks from the indoor unit.
Switches or buttons do not operate properly.
Fault code is displayed on the controller.

8. Warranty key points in large print.
Sygnal HVAC systems used in human comfort applications are covered by a parts and labour on-site warranty
as explained in detail later in this document. Sygnal is committed to making sure that our clients get years of
trouble free operation from what we believe to be the world’s best residential concealed ducted air
conditioning system. Like all warranty policies the Sygnal HVAC warranty provides peace of mind for clients
and details the rights and responsibilities of Sygnal and the client.
HVAC systems like all machines require regular maintenance. If regular maintenance is not completed the
system operation is compromised and although Sygnal systems have many safety systems built into their
operation system longevity will be compromised. In most residential environments a single service per year
completed in accordance with the programmed maintenance schedule is sufficient to ensure that system
performance is not compromised and warranty terms and conditions are met.
Sygnal tracks all activity relating to your system and all other systems no matter where they are installed. This
allows us to make sure that all performance information is passed directly back to our Engineering Team so
that Future Sygnal systems can continue to set a new standard in product reliability. Tracking all system
activity also helps our Service Team identify any environmental factors, unusual activity or a repeat faults. To
achieve the required level of tracking to provide peace of mind for our clients we require that all systems are
registered on the Sygnal website within the first twelve months of operation. Immediately on completion of
the online registration form a unique identifier will be sent to the nominated email address, your system
warranty will be extended from twelve months to six years from date of manufacture or five years from date
of installation (whichever expires first).
1. Register your system: https://www.sygnal.com.au/register-your-system
2. Keep your system well maintained (If a fault occurs due to lack of maintenance or would have been rectified
sooner if noted during programmed maintenance your claim may be declined or reduced).
3. Be mindful of possible travel charges (is there an appointed service agent within 100km from your home?).
4. Be mindful of broader system components that are not unmanufactured by Sygnal and may have different
warranty terms and conditions (This may include iPads, motorised dampers, three phase soft start modules,
ductwork, diffusers and grilles).
5. Be mindful that in the rare event that a failure occurs the replacement component is covered by twelve
months or the remaining term of the system wide warranty whichever is the longest. System Registration
