Indicator	status	Meaning
Red indicator light	on	Temperature output work
Red indicator light		off	Temperature output shutdown
Blue indicator light	on	Timing output work
Blue indicator light		off	Timed output shutdown

4. User menu description

3.1 User menu

menu	name	Parameter range	Factory setting
SE	Control temperature	F2~F3	32℃
F6	Timing output stop time	0~99 (unit is determined by F12)	15minutes
F7	Timing output power-on time	0~99 (The unit is determined by F12)	1minute

4.2 Control temperature setting: ◆In the running state, press the "temperature" button, the blue digital tube on the right will display "SE", and the left will display the control temperature. At this time, press the "▲" key or "▼" key to change the temperature set value and set After finishing, press the "temperature" button to save and exit.

4.3 Timing setting: ◆In the running state, press the "timing" button, the blue digital tube on the right will display "F6", and the left will display the corresponding timing shutdown time. At this time, press the "▲" key or "▼" key to change this set value , Press the "timing" button again, the blue digital tube on the right will display "F7", and the left will display the corresponding timing power-on time. At this time, press the "▲" key or "▼" key to change the set value, and the setting is complete Then press the "timing" button to save and exit.

FB	High and low temperature alarm return difference	1℃~20℃	2℃
FC	Temperature alarm delay	0~60minutes	2minutes
FD	Timing unit selection	0: Timing start and stop unit is minute 1: Timing start and stop unit is hour 2: Timing shutdown unit is hour, startup is minute	0

5.2 System menu setting: ◆In the running state, press the "▼" key and the "temperature" key at the same time for more than 3 seconds to display "F1" on the blue digital tube, the system enters the parameter menu setting state, and the left side can be changed by pressing the "▲" or "▼" key. For the parameter corresponding to the red digital tube, press the "temperature" button again to switch to the next parameter "F2", the same setting method, press the

"timing" button to save and exit after setting。

6. Function Description 6.1 Refrigeration control (F8=0) ◆After the compressor has passed the delay protection time, when the cabinet temperature is greater than or equal to the control temperature + temperature return difference (F1), the compressor starts; when the cabinet temperature is less than or equal to the control temperature, the compressor stops.

6.2 Heating control (F8=1) ◆After the heater has passed the delay protection time, when the cabinet temperature is less than or equal to the control temperature-temperature return difference value, the heater starts; when the cabinet temperature is greater than or equal to the control temperature, the heater stops.

6.3 Timing control ◆When the controller finishes running the timing output stop time, the timing indicator light will be on and the timing output will be on. When the timing stop time is finished, the timing indicator light will be off, and the timing will stop, and it will run cyclically. ◆Timed start-up time and timed stop time are displayed as countdown.

6.4 Alarm control ◆When cooling or heating is started once and stopped, the high and low temperature alarm function is activated. When the cabinet temperature is higher than or equal to the set high temperature value F9 and the duration exceeds FC, the high temperature alarm is triggered and the temperature flashes; when the cabinet temperature is lower than or equal to the set low temperature value FA and the duration exceeds FC, the low temperature alarm is triggered, the temperature Flashing. ◆When the cabinet temperature sensor fails, "EE" is displayed.

6.5 Switch control ◆Long press the "▼" key for more than 5 seconds, the display "---" means shutdown, and then press the "▼" key again to turn it on.

7. Wiring diagram

8. Safety Precautions ◆The power supply voltage should be consistent with the voltage marked on the machine. ◆Strictly distinguish the three interfaces of power cord, output relay, and sensor, and don't connect them wrongly! The load must not exceed the contact capacity. ◆Wiring work must be performed with the power supply completely disconnected, and a good crimp connection between the wire and the terminal should be ensured. ◆ It is forbidden to use in high temperature, high humidity, strong electromagnetic interference, strong corrosive environment. ◆ In order to avoid possible interference, it is recommended to keep a proper distance between the sensor lead and the power cord.
