Press SET key to revert to PV display.
000: Buzzer off
001: Buzzer on

time) alternately. Press SET key to revert to PV display.
8. Differential (The point of compressor ON and OFF )
COMP ON:
COMP OFF:
SV +0.4㷄
SV -2.2㷄 (for SV is -90㷄~-60㷄), SV -0.5 (for SV is -59㷄~-50㷄)
9. Offset value
1) PV+0.5㷄 is the offset value to adjust the difference between temperature of temp. sensor
and the center of internal chamber.
2) PVat + (-3.0C) is the offset value to correct the ambient temperature.
*Note) PVat = Temperature of AT sensor
10. Remote alarm terminal
In normal condition:
㸣
In alarm condition &
power failure :
Remote alarm contact is N.O. N.C.
㸣
Remote alarm contact is N.C. N.O.
11. Cycling of High stage compressor
If the filter sensor is higher than or equal to 60㷄, the High stage compressor will be turned off.
When the filter sensor is within 10㷄 of the ambient temperature sensor, the High stage
compressor will be allowed to turn back on.
12. Sensor failure
(1) Temp. sensor
Open circuit:
E01 and 50㷄 are displayed alternately, the buzzer beeps intermittently
and remote alarm contact outputs.
The compressor would be allowed to turn on.
Press BUZZER key to stop the buzzer beeping.
Short circuit:
E02 and -170㷄>PV>-180㷄 are displayed alternately, the buzzer beeps
intermittently and remote alarm contact outputs.
The compressor would be allowed to turn on.
Press BUZZER key to stop the buzzer beeping.
(2) Cascade sensor
Open circuited: E03 and PV are displayed alternately, the buzzer beeps intermittently
and remote alarm contact outputs.
The resistance value would be 㺙㱅 and temperature would be -34.1㷄
or lower. Compressor (L) is not forcibly turned off.
Press BUZZER key to stop the buzzer beeping.
Short circuited: E04 and PV are displayed alternately, the buzzer beeps intermittently
and remote alarm contact outputs.
Press BUZZER key to stop the buzzer beeping.
The resistance value would be 0㱅 and temperature would be -12㷄 or
higher that causes to be compressor (L) failure. Compressor (L) is
forcibly turned off.
