Slave Bypassed
This message is seen at the master as a B on the display in place of the slave number.
This indication is not actually a fault but indicates an action was taken by the user to
prevent the operation of a slave.
VFD Trouble
The Variable Frequency Drive (VFD) has reported a fault. See the documentation for the
VFD to determine the cause and resolution.
Lockout
The master keeps fault count for each slave. If four faults occur on a slave without this
count being reset, the master will prevent that slave from operating. This is called a
lockout and is indicated on the master with an L on the master status screen in place of
the slave number. A lockout is cleared by pressing the unlock button. The fault
count for a slave is reset when it is unlocked, the power button is pressed, or if the master
turns off the slave.
Pump Not Responding
This fault is seen at the master if a programmed pump control is not responding.
Low Seawater Temperature
Seawater temperature is below 40°F (4.4°C) for over 5 minutes in reverse cycle heat.
