4.2- CANCELATION: when RT-SENSOR is working normally.
1) START: by pressing TEMP. CONTROL button 30 times continuously.
2) CANCEL: by pressing TEMP. CONTROL button 30 times continuously
Cf. the system generally operates when the limit time 60 hrs. passes.
3) DISPLAY: All of LED lamps are on.
4) CONTROL: COMP & FAN will be on independent of the operation
condition. (There is no defrost mode on this test.)
1) HOW TO REDUCE: (There is no FAST KEY on PCB for MP.)
1 min: click FAST KEY one time.
30 min: if you press FAST KEY continuously, you can reduce 30 minutes
on each second.
2) Practical Use: can be applied to reduce needless time on test.
EX) function of stop for 6 min.
1) START: by pressing FUZZY button one time
2) CANCEL: by pressing FUZZY button again.
3) DISPLAY: start - VAC~4 LED lamps and AUTO LED lamp on.
cancel -It returns to the last TEMP. MODE.
4) CONTROL by RT-S
•Protection for over-cooling of Room vegetable.
1) LOW RT TEMP: RT SENSOR ≤ 24ºC
2) Hysteresis Difference: 1ºC
2.1- Mode of LOW TEMP.: RT SENSOR ≤ 24ºC
2.2- Mode of General TEMP.: RT SENSOR ≥ 25ºC
2.3- Mode of TEMP. just before control: 24ºC≤RT-S≥25ºC
• During operating under 19ºC, the system operates on LOW RT
Mode until the temperature arrives between 24ºC and 25ºC
RT-S: ~24ºC(operating) 24~25ºC (arriving)
•During operating over 25ºC, the system operates on General RT Mode
until the temperature arrives between 24ºC and 25ºC
RT-S: ~25ºC(operating) _ 24~25ºC (arriving)
3) Control
2.1 -When Comp. is on, R-SENSOR HTR is off.
When it passes 6 min after COMP. was off, R-SENSOR HTR is on.
