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.
