Control Function Instruction
Temperature control
eat mode【t0 = 】
When Room temp. ≤ Set temp. (TP) –【t1】, and Temp. Output (R3) has stopped for【t2】,
Temp. Output (R3) will be energized.
When Room temp. ≥ Set temp. (TP), Temp. Output (R3) will be deenergized.
Cool mode【t0 = C】
When Room temp. ≥ Set temp. (TP) +【t1】, and Temp. Output (R3) has stopped for【t2】,
Temp. Output (R3) will be energized.
When Room temp. ≤ Set temp. (TP), Temp. Output (R3) will be deenergized.
Over high temperature limit protection (only for heat mode)
When Room temp. ≥ Set temp. (TP) +【t4】, Fan Output (R1) will be energized.
When Room temp. ≤ Set temp. (TP) +【t4】-【t5】, Fan Output (R1) will be deenergized.

umidity control
umidify mode【h0 = 】
When Room humidity ≤ Set humidity ( P) -【h1】, and Humi. Output (R2) has stopped for【h2】,
Humi. Output (R2) will be energized.
When Room humidity ≥ Set humidity ( P), Humi. Output (R2) will be deenergized.
Dehumidify mode【t0 = P】
When Room humidity ≥ Set humidity ( P) +【h1】, and Humi. Output (R2) has stopped for【h2】,
Humi. Output (R2) will be energized.
When Room humidity ≤ Set humidity ( P), Humi. Output (R2) will be deenergized.
Over high humidity limit protection (only for humidify mode)
When Room humidity ≥ Set humidity ( P) +【h4】, Fan Output (R1) will be energized.
When Room humidity ≤ Set humidity ( P)】+【h4】-【h5】, Fan Output (R1) will be deenergized.
Turn egg control（R4, R5）
Egg-Turn Output will be energized (R4 and R5 alternatively) for【u1】after deenergized for【u0】,
periodically.
One full egg turn = one left turn (R4) + one right turn (R5).
There will be no egg turn after full egg turn has executed for【u2】times, and the egg turn signs will
blink.
Keeping【▲】depressed for 2 seconds starts manual egg right turning; keeping 【▼】depressed for
2 seconds starts manual egg left turning.
Pressing 【S】and【▼】simultaneously shows the full egg turn counter value.
Power on reset will reset the full egg turn counter value to zero.
Timer exhaustion control (R1)
Fan Output (R1) will be energized for【u4】after deenergized for【u3】, periodically.
Warning control
When there is warning, the buzzer will beep.
The buzzer warning could be stopped/restored by pressing【P】.
igh temp. warning: if Room temp. ≥ Set temp. (TP) +【t6】, Room temp./“t i” displays alternatively.
Low temp. warning: if Room temp. ≤Set temp. (TP) -【t7】, Room temp./“tLo” displays alternatively.
igh humidity warning: if Room humidity ≥ Set humidity ( P) +【h6】, Room humidity//“h ” displays
alternatively.
Low humidity warning: if Room humidity ≤ Set humidity ( P) -【h7】, Room humidity//“hL” displays
alternatively.
The warning Press【P】
Sensor
The Room temp. can be calibrated. If Room temp. is 0.2℃ lower than real temp., set 【t3】= 0.2.
The Room humidity can be calibrated. If Room humidity is 2%R higher than real, set 【h3】= -2.
When sensor fails, the Temp. and Humi. Output (R3, R2) will be deenergized, and “E01” will display.
Note: do not plug in/off the sensor when power supplied.
