GENERAL OPERATING/WARRANTY MANUAL

FOR CHILLER, FREEZER AND HEATED DISPLAY CABINETS

4. COMPRESSOR

4.1 When indoor temp.

≥

(tS + td). compresssor turns ON. When indoor temp

≤

tS, compressor turns

OFF.

4.2 After the compressor turns off, the compressor protection time “AC” starts to count.

After the compressor protection time is reached, the compressor could be re-started again.

4.3 Even compressor protection period is set as AC=0, when the power re-supply, there will be 1 min

delay for protection purpose.

4.4 When the indoor sensor and memory fail, compressor operates and stopped cyclically for every

15 minutes, (default setting, cannot be changed).

4.5 When the input voltage error E3,E4, the compressor stops operating.

5 Defrost: Compressor stopped to defrost

5.1 When defrost, the compressor stopped, but the fan operates, and the defrost indicator flashes.

5.2 When the defrost period is reached or the defrost is manually ended, the system returns to

operation mode and the compressor will operate according to the temp change.
5.3 If the defrost “dt” and defrost cycle “df” are changed, it will take effect immediately and

be recalculated.

5.4 The defrost cycle “dF’ includes manual defrost period and auto defrost period.

5.5 After the controller is turned off, the defrost cycle and defrost period would be recalculated.

5.6 The first operating cycle does not defrost after power supply.

5.7 Defrost temp. Lock dL=0, the actual indoor temp displays during defrosting.

5.8 Defrost Temp. Lock dL=1:

5.8.1 Defrost Lock Display dd=0, dF displayed during defrost lock status.

5.8.2 Defrost Lock Display dd=1, the temp before defrost displayed during the defrost lock status.

5.8.3 Defrost lock period Lt=0, when indoor Temp.

≤

Setting Temp., the defrost lock status will be

unlocked.

5.8.4 The defrost lock period Lt

≠

0, when defrost lock period is reached, the defrost lock status

will be unlocked.

6 Fan:

6.1 Under non- malfuntion status, the fan is off during defrosting or dripping.

6.2 Fan Operation Selection FC=0, and evaporator temp. < fan stop temp., fan is ON.

6.3 Fan Operation Selection FC=0, and evaporator temp.

≥

fan stop temp., fan is OFF.

6.4 Fan Operation selection FC=1, and evaporator temp. < fan stop temp., fan turns ON when

compressor starts.

6.5 Fan Operation Selection FC=1, and evaporator temp.

≥

fan stop temp., fan is OFF.

6.6 When the sensor and memory fail, fan and compressor operated and stopped cyclically for

every 15 minutes. (default setting, cannot be changed).

6.7 When the input voltage error E3 E4, the fan turns OFF.

7. Defog:

7.1 Defog function is OFF when the controller is OFF or defog switch is Off.

7.2 When the controller is ON and defog switch is ON, if defog cycle gF=0, defog ON/OFF could

be controlled by defog switch.

7.3 When the controller is ON and defog switch is ON, if defog cycle gF

≠

0, the defog function

operates according to the defog cycle “gF” and the defog period “gt”.

8. Input voltage:

8.1 When the input voltage higher than AC 255V lasts longer than the High and Low Voltage Alarm

Delay “Ud”, high voltage alarm E3 will be activated.

8.2 When the input voltage lower than AC 182V lasts longer than High and Low Voltage Alarm

Delay “Ud”, low voltage alarm E4 will be activated.

9. Indoor Temp Lock:

9.1 When the indoor Temp Lock tL=0, the function of indoor temp. lock stops.

9.2 When power on and the indoor temp reaches temp. setting once, the function of indoor temp.

Lock starts.

9.3 Under normal operation mode (non-malfunction/defrost/defrost lock), when tL

≠

0 and indoor

temp. detection

≥

(tS + tD), the temp display is locked and indoor temp lock “tL” starts to count.

9.4 When the indoor temp is locked, the indoor temp detection < temp setting “tS” + temp difference

“td”, the Indoor Temp Lock would be unlocked immediately.

9.5 When the indoor temp lock “tL” finished, it will unlock. The function of indoor Temp Lock stops

until the indoor temp detection <temp. setting “tS” + temp. difference “tD” is detected again.

10. Indicators:

10.1 Compressor

: When the compresor is ON, the indicator is ON: when the compressor is

protection delay, the indicator is flashing; when the compressor is OFF, the indicator is OFF.

10.2 Fan : When the fan is ON, the indicator is ON; when the fan is OFF , the indicator is OFF.
