Upon powering the unit, the Symbio 700 performs self
diagnostic checks to verify all internal controls are
functional. When the user interface is ready or the mobile
app is connected to the Symbio 700 controls, use the
following test procedure to start the unit at the control
panel. Each test step can be activated individually by
selecting the unit operating stage desired. The unit can be
left in any test step for up to one hour (adjustable to values
between 1 and 120 minutes) before Service Test will
automatically terminate. Once Service Test has been
terminated, a system reset will occur and the unit will revert
to the normal system control.
