3.1.8.3 If no more command is given within 5 seconds or press
[SET]
button, parameter will
be saved automatically and return to indoor temperature showing.
3.2 Function:
3.2.1 Operation of compressor:
3.2.1.1 When indoor temperature
≤
“tS”, compressor OFF: when indoor temperature
≥
( “tS” , “td” ),
compressor On: If the time of AC delay doesn’t arrive, compressor OFF.
3.2.1.2 When the compressor stops, it starts to count the time of AC.
3.2.1.3 When the power supply, the compressor will delay at least one minutes to start.
(When AC=0)
3.2.1.4 During defrost time, please refer to Manual 3.2.2 about the defrost operation.
3.2.1.5 Break down operation: When E1,E2,E4,EE, the compressor starts according to
“Cr” time and operates automatically according to “CS” stopped time.
3.2.2 Manual defrost:
3.2.2.1 Calculation of defrost:
3.2.2.1.1 When the controller turns on, the first defrost period will not defrost. The
defrost will be re-calculated and start on the second period. (for example: if
“dF” sets 6 hours, the cycle of defrost will be started on the 6th hour.)
3.2.2.1.2 When the time arrives “dF” the defrost mode starts (defrost automatically): if
it is already in the manual defrost condition, the defrost time will not be
recalculated.
3.2.2.1.3 Defrost manually (in normal mode, press
[
▲
]
and
[
▼
]
button for 3 seconds in
the meantime) can enter/end the defrost mode manually. It will not affect the
calculation of defrost cycle.
3.2.2.1.4 If the controller breaks down or alarms, the defrost cycle will not be affected.
3.2.2.1.5 After amending “dF” , the new setting value will be loaded in next cycle: after
amending “dt” , “dt” becomes effectively, if you miss to set the defrost during
the defrost automatically cycle or “dt” setting, it will be loaded in next cycle.
3.2.2.2 Defrost operation:
3.2.2.2.1 Parameters
“dO”
and
“dr”
works in this RS-411.
3.2.2.2.2 Power-off defrost applies on RS-411.
3.2.2.2.3 When defrost begins, it starts to calculate “dt”. Compressor is OFF,
Fan is On.
3.2.2.2.4 When indoor temp.
≥
“dS” during defrost period, defrost ends immediately.
3.2.2.2.5 When “dt” time ends - defrost Off.
3.2.2.3 End of defrost: When
“dt”
time ends - it returns to normal operation mode.
3.2.2.4 Defrost temp. locked( “dL” ).
3.2.2.4.1 When “dL”=0 , after entering the defrost mode, indoor temperature shows
normally.
3.2.2.4.2 When “dL”=1 , after entering the defrost mode, indoor temperature reaches
the entered defrost temperature : After finishing defrost, if indoor
temperature detection
≤
set point (
“tS”
) it will restore to show the normal
indoor temperature.
3.2.3 Fan operation:
3.2.3.1 Parameter “Ft” works in RS-411.
3.2.3.2 During the defrost time, fan On.
3.2.3.3 Fan select “FC”=0 , the compressor will ON/OFF.
3.2.3.4 Fan select
“FC”=1
, fan operates continually ON.
3.2.4 Memory shut down: When the shut down happens during the operation, after power restores,
the system will operate refer to the parameter value before shut down. (the memory doesn’t
include the defrost condition/cycle).
3.2.5 Indoor temperature compensation: Showing temperature = indoor detective tempe
probe calibration ( “Ot” ).
3.2.6 Temperature alarm:
3.2.6.1 When indoor temperature is higher than
“AU”
(UA/indoor temperature alternant
glisten) or lower than
“AL”
(La/indoor temperature alternant glisten), it starts to
calculate the alarm delay ( “Ad” ), after delay protection ends, the alarm starts
(condition : after turn on the machine, the temperature alarm function appears only if
indoor temperature has been reached to set temperature).
3.2.6.2 Board temperature alarm : when the board temperature
≥
95 °C, the controller closes
the output contact compulsorily and show “tA” the alarm starts immediately :
waiting until the board temperature
≤
75 °C, the alarm removed.
3.2.6.3 Condenser temperature alarm : when the condenser temperature
≥
“Ct” , the
controller closes the output contact compulsorily and show “
CA
/indoor temp.”
alternant glisten : waiting until the condenser temperature
≤
“Ct”
., the
“CA”
alarm
removed.
