Suction Pressure
Control Activation
Level
SucPress Act Lvl
When the suction pressure drops below this level for more than
the Q5-26 time, Suction Pressure Control is activated allowing
it to affect the output frequency. When the suction pressure rises
above this level for more than the Q5-26 time, Suction Pressure
is deactivated causing it to have no effect on the output
frequency.
Suction Pressure Control is always active (if enabled) when set
to 0.
Default: 10.0

When the suction pressure drops below the Q5-25 level for more
than this time, Suction Pressure Control is activated allowing it
to affect the output frequency. When the suction pressure rises
above the Q5-25 level for more than this time, Suction Pressure
Control is deactivated causing it to have no effect on the output
frequency.
