2——Mode setting
1) Mode setting page can be selected by the local wire controller button operation, and under
this page, you can set the number of the unit which needs to operate.
A) On Auto mode, the mode setting is for the whole unit. The number of the units is that of
the online unit which can not be changed. The unit for start or stopping is selected by
electric controller of the main unit.
B) On Manual mode, the mode setting is for the online unit and the number of the unit can
be changed. After setting, the ON/OFF of the actual unit is controlled by wirer
controller. If you choose turning on unit, units will start in the sequence from low
address to high address until achieving the number selected. If you choose turning off
unit, units will be turned off in the sequence from high address to low address until
achieving the number selected including the units which delays to start during unit
running term.
C) When choosing Manual mode to start unit, units will start every 6s’ interval in the
sequence from low address to high address (the units which has started are free of
this 6s limit) until achieving the number selected. If one unit fails, wire controller will be
turned off it, and start the next unit in the sequence from low address to high address.
If there is no unit available, the controller will just turn off the failed one and display
corresponding failure code. When the failed one recovers, it will restart, meanwhile
the replacement will be turned off.
D) When choosing Manual mode to start unit, if one unit compressor fails and stops, it will
be restart 3 minutes later, so the start orders of this unit and the others with higher
address need to delay for 3 minutes to send, which can avoid multi-compressors
starting simultaneously.
E) Choosing Manual mode to close unit, units will be turned off in the sequence from high
address to low address.
F) Starting water pump on Manual mode is only available for the main unit. Main unit can’t
be replaced when the it fails.
G) The water pump working mode is just available for the main unit while there is no water
pump mode in auxiliary unit. After setting, irrespective of the number of unit, the wire
controller only sends the order to main unit to start up, while the auxiliary units keep
off.
H) The current setting information can not be sent to the main unit until pressing
CONFIRM. Once pressing CONFIRM, the mode setting light will be turned on, and the
order will be sent. The light will be off after it receive the response.
