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.

2.7 Setting a zone temperature / Position (setpoint)

Zone damper behaviour is determined by whether a zone sensor is connected to the zone sensor output at the

zone control modules. If a sensor is detected the zone is configured for temperature control. If no sensor is

detected and the enable zone dipswitch is turned on the zone is configured for damper positioning control.

1. Press ZONE or or to select the target zone.

2. Press SET to adjust the target temperature / position.

3. Use or to adjust the set point to the desired level.
