condition of compressor activation/halt:
◆ The shortest operation time and halt time of compressor should be met.
6.7 Fault detection and protection
◆ Compressor protection
the shortest halt time of compressor is 3 min. and it must be re-initiated for
fault detection and actions after at least 3 min.
!

The compressor will restart in 1 min. delay after the reset of compressor and the
downtime of compressor is larger than the shortest halt time(3 min.)
◆ Fault codes lookup
in case of new fault, the Nixie tubes get to show the relative information;press
“▲+SET” in the main interface to look up the first malfunciton in record when
the reset is not proceeded, press“▲ ” or“▼ ” to repeatedly find the other
faults in queue, press“▲+SET”to quite the fault lookup interface.

condition of its stoppage：inside temperature<[ fan starting 15]-2 celsius(defult 12 celsius).
◆ logic control of external circuit fan
external fan and compressor delay to coordinate, after 5 s of compressor activation,eternal
fan is started; while the fan is halted after 5 s of compressor stoppage.
◆ compressor of external circuit fan
after 10 s of internal fan activation, system checks if the inside temperature can be met to
start up the compressor：
condition of its activation： inside temperatre≥[ refrigerating temperature](defalut 35
celsius,settable)；
cndition of its halt：inside temperature <[refrigerating temperature]- [difference
3](default 32 celsius).
