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.

2. Connect LCD Touchpad Functions
The LCD touchpad allows you to adjust various aspects of your indoor climate. By default access to all control
functions are available from all LCD touchpads. Press any button on the touchpad to wake it (the LCD backlight
will come on).
Access to some control functions may be limited via hardware settings during installation. In the following
pages, functions which may be limited in this manner will be indicated with a * in the heading.
If access to a function has been limited the LCD touchpad will respond with a beep only. (For more information
refer to Sygnal Connect Installation Manual).
Access to the following functions is available by default from any LCD touchpad.
Turn all zones on or off at once.
Select the system operating mode (Heat, Cool, Auto, Vent).
View any zone status.
Turning any zone on/off.
Setting any zone target (temp set or flow set).
Select the individual zone mode (temperature or velocity target).
Naming a zone.
Setting the system clock and timer programs.
Setting individual zone timer programs.
