4. OPERATION
The Raystat V5 has a LED user screen interface:
The unit will switch to the main screen after 2 minutes of non-interaction on the
parameter input screens.
4.1 Quick install
When the unit is powered up for the first time, a quick setup must be executed before
the unit is ready to start. The Quick start helps to set all important settings, the
unit will go in main screen mode automatically when done. Quick start is sufficient
for normal operations. More settings are available in the Setup menu for special
installation conditions.
The Quick start will only start if no pre-setting is done.
The parameters can be changed by pressing the check mark button for 6 sec.
The controller can be protected by a keylock. If this keylock function is active, the
code (see SP 12 in parameter list) needs to be entered to unlock the unit. Resetting
the Raystat V5 to factory settings is done by simultaneously pressing the arrow up,
down arrow and OK buttons for 6 seconds.
