4 User Menu Settings: Under running status, press and hold SET key for 5 sec until the Room Temp display screen appears SET to enter user menu setting mode, the on temp indicator light on, then to page down and check the parameter item by repeatedly pressing SET key, the indicator light will be on when the accordingly parameter item appears in screen. After entering the user menu, press and key to modify the parameter setting value in the Set Temp display screen. System Menu Settings: Under running status, press and hold bot SET key and key simultaneously for 5 sec, until the Room Temp display screen appears F1 item, the system enters the system menu setting mode, then to page down and check all the parameter items by repeatedly pressing SET key. After entering the system menu, press and key to modify the parameter value in the Set Temp display screen, all the parameter indicator lights are off at this time. Administrator s Menu Checking: Under running status, press and hold SET key for 3 sec until the on temp indicator light on, you can page down and check all the parameter items by repeatedly pressing SET key, and the parameter indicator light on with the accordingly parameter item is chosen. Under parameter checking mode, the parameter cannot be modified. If hold pressing the SET key for 3 sec or no key operations within 10 sec, exit from the parameter checking mode, on the Room temp display screen, it appears the current storage temperature. Under running status, press and release the key (Defrost surplus time), the Room Temp display screen appears defrosting surplus time and system exits 5 sec later. Under running status, the defrost time and the defrost cycle is not as 0, under the non-defrosting status, the defrost sensor temperature is lower than the setting defrost stop temperature, pressing the key (Forcible defrost key) for 5 sec to enter the forcible defrosting status, the defrosting indicator light is on, Under running status, during the defrosting procedure, pressing the (Forcible defrost key) for 5 sec to exit from defrosting status, the defrosting indicator light is off.

5 Under running status, and non-defrosting, non-refrigeration, non-dripping, when the storage temperature is higher than the stop temp, meantime is lower the start temp, pressing the key ( Forcible refrigerating key) for 5 sec to enter forcible refrigerating status, refrigerating indicator light flashes when compressor delay time not exceed the set delay time. Refrigerating indicator light is on when compressor delay time exceeds the set delay time. Under running status, pressing key ( Forcible refrigerating key) for 5 sec to exit from the refrigerating status, the refrigerating indicator light is off. Under running status, press and release the key to cancel the alarm sound. Under running status, press and release key, the Room Temp display screen appears the defrosting sensors temperature, 5 sec later it exit automatically. Function Control Output: 1) Compressor Control Compressor start up when all the following conditions are satisfied: a) Compressor delay time exceeds the setting compressor delay time. b) Under the non-defrosting, dripping while defrost is not going status, the storage temperature is the setting start temperature or when the forcible refrigerating or hot gas defrosting. Compressor close when any of the following condition is satisfied a) The storage temperature the setting stop temperature b) When the electric heating defrosting start c) When hot gas defrosting is end d) When forcible refrigeration is end 2) Defrost Control Defrosting start when all the following conditions are satisfied: a) Both defrost time and defrost cycle are not set as 0 b) The storage temperature the setting defrost stop temperature c) When system reaches the setting defrost cycle time, or the forcible defrosting starts Defrosting stops when all of the following are satisfied: a) When defrost time is set as 0 b) When defrost cycle is set as 0 c) Defrosting running time runs out d) Defrosting temperature is higher than defrosting stop temperature e) Pressing the ( forcible defrost key) to end defrosting

6 3) Alarm Output Controller own 1 output: buzzer alarm sound output. Under the running mode, when the sensor error or temperature exceeds the temperature range or when the buzzer alarms, please press and release the key to cancel the alarm sound. Wiring Diagram: Error Code Function Explanation: Code E1 E2 E3 E4 Reasons and Display Mode Sensor will be short circuit open circuit if the storage sensor is not connected in a correct way, and the refrigerating run as per mode: stop for 30 mins and run for 15 mins, the buzzer output. Sensor will be short circuit or open circuit if the defrost sensor is not connected in the correct way, and the defroster will run as present defrost cycle and the defrost duration time, meanwhile the buzzer output. Refrigerating will run as the proportional time (stop for 30 mins and run for 15 mins) when the storage temperature exceeds the setting temperature upper limit, the buzzer output. Defroster will run as the present defrost cycle and the defrost duration time when the storage temperature exceeds the setting temperature upper limit, and the buzzer output.

7 Safety Rule: Danger 1. Strictly distinguish the sensor down-lead, power wire and output line of the relay, and prohibit wrong connections or overloading the relay. 2. Prohibit connecting the wire terminals without electricity cut-off. Warning Prohibit using the machine under the environment of over damp, high temperature, strong electromagnetism interference or strong corrosion. Notice 1. The power supply should conform to the voltage value indicated in the instruction, and make sure the power supply is steady. 2. To avoid the possible interference, the sensor down-lead and power wire should be kept a distance.
