Key operation

· Check parameter set value:

Press ▲ and then loosen to display the set upper limit; Press and then loosen▼to display the.

Modify parameter set value

· Press set for more than 3s to cnter into parameter modifying status the last,display the last adjusted

menu after electrified with parameter modifying indicator light on.

· Press ▲ or▼to go forward or backward the menu item; press set to display the current.

Parameter set value

· Press set and ■ or ■ simultaneously can adjust the current parameter set value;press set and ■

simultaneously more than 1s will increase current parameter set value quickly; press set and ■

simultaneously more than 1s will decrease current parameter set value puickly;

· Press rst or no key operation in 30s will save the modified parameter and retutn to normal

temperature display status.

Restore the parameter setting

· When electrify the controller,first check the

parameter setting,if parameter setting is

wrong, LED display E1 with buzzer sound,at

this time press Set will restore default

parameter setting.

· Advise to reset the parameter.

Control output

· Compressor: When the storage temp.Is higher than set temp.Upper limit,compressor starts,

lower than set temp. Lower limit,compressor stops, When sensor errir, compressor works

proportionably as on -15 minutes off -30 minutes. After electrified or compressor stops .

Compressor restart-up is allowed after running out of compressor protection time.

· Alarm: While temp.exceeding valus is not 0.LED blinkingly displays current temperature

when storage temperature is higher than set temperature upper limip +exceeding temp

value or lower than set lower limit-exceeding temp. value. When rumming out of the

exceeding temp.limit alarm delay after electrified. exceeding temp.limit alarm starts

with buzzer sound,and alarm cancel when temperature return to normal temperature

LED blinkingly Display E1 with buzzer sound when memorizer error; display E2 with

buzzer sound when sensor error, Display HH when temp. Higher than 99°C and lower

than 120'C. Press any key to cancel alarm sound, but alarm status remains.

Safety regulations

· Danger: Strictly distinguish the sensor down-lead,power wire and output relay interface

from one another,prohibit wrong connections or overloading the relay. All connections

should be modified under electricity cut-off.

· Warning: Prohibit to use the machine in water or under the environment of ower damp,

high temperature,string electromagnetism interference ir string corrosion.

· Caution: The power supply should conform to one labeled on the machine,and ensure

the stability of the power voltage. Sensor down-lead and power should be kept for a

proper distance to avoid possible interferences.
