Control

Multifunction Output R1

Over hot / wet protection: If R1 drives an exhaustion fan, it has the function to cool down or dry quickly.
Ref. to

Temperature control

-> Over hot protection, and
Humidity control
-> Over wet protection.
Timer output: R1 will be energized for【u4】after de-energized for【u3】, periodically.
Temperature control

Heat mode 【t0 = H】

If Room temp. ≤ Set temp. (TP) –【t1】, and Temp. Output (R3) has stopped for【t2】, then Temp. Output will be energized. If Room temp. ≥ Set temp., then Temp. Output will be de-energized.
Suzhou Lily Tech. CO., Ltd.
Page 4, Total 7 Pages

Cool mode【t0 = C】

If Room temp. ≥ Set temp. +【t1】, and Temp. Output has stopped for【t2】, then Temp. Output will be energized. If Room temp. ≤ Set temp., then Temp. Output will be de-energized.

Over hot protection

If Room temp. ≥ Set temp. +【t4】, then output R1 will be energized. If Room temp. ≤ Set temp. +【t4】-【t5】, then output R1 will be de-energized. This protection function is only effective in heat mode. If【t4】=【t5】= 0.0, disable the protection function.

Humidity control

Humidify mode 【h0 = H】

If Room humidity ≤ Set humidity (HP) -【h1】, and Humi. Output (R2) has stopped for【h2】, then Humi. Output will be
energized. If Room humidity ≥ Set humidity, then Humi. Output will be de-energized.

Dehumidify mode【h0 = P】

If Room humidity ≥ Set humidity +【h1】, and Humi. Output has stopped for【h2】, then Humi. Output will be energized. If Room humidity ≤ Set humidity, then Humi. Output will be de-energized.

Over wet protection

If Room humidity ≥ Set humidity +【h4】, then output R1 will be energized. If Room humidity ≤ Set humidity +【h4】-【h5】, then output R1 will be de-energized. This protection function is only effective in humidify mode. If【h4】=【h5】= 0.0, disable the protection function.

Timer output R4 and R5

R4 and R5 are controlled by parameter【u0】,【u1】and【u2
】
.
R4 and R5 will be energized for【u1
】
time alternatively. A period includes an R4 energized and an R5 energized.
There is a counter counting the times of the period. Every time after the power supplied, the counting value is reset to zero.
keeping 【S】and【▼
】
depressed simultaneously will show the counting value for 3 seconds.
If 【u2】> 0, when the counting value reaches 【u2
】
, R4 and R5 will stop energized, and display and will blink.
If 【u2
】
is set to zero,R4 and R5 will never stop energized.
Forced energized manually:
Keeping【▲
】
depressed for 2 seconds makes R5 being energized, until the key is released.
Keeping【▼
】
depressed for 2 seconds makes R4 being energized, until the key is released.
R4 and R5 could be used for incubator egg tray control.

Alarm

High temp. alarm: if Room temp. ≥ Set temp. (TP) +【t6】, display “tHi”. If【t6】= 0.0, the function disable. Low temp. alarm: if Room temp. ≤ Set temp. -【t7】, display “tLo”. If【t7】= 0.0, the function disable. High humidity alarm: if Room humidity ≥ Set humidity (HP) +【h6】, display “hH”. If【h6】= 0.0, the function disable. Low humidity alarm: if Room humidity ≤ Set humidity -【h7】, display “hL”. If【h7】= 0.0, the function disable.

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%RH higher than real, set 【h3】= -2. When sensor fails, the Temp. and Humi. Output (R3, R2) will not be energized, and “E01” will display. Note: do not plug in/off the sensor when power supplied.

Keypad lock

Keep〖S〗and〖P〗depressed simultaneously for 3 seconds to lock the keypad, “Lo” displays for 3 seconds. When keypad locked, any key press will not be executed, but display “Lo”. Keep〖S〗and〖P〗depressed simultaneously for 3 seconds to unlock, “Un” displays for 3 seconds.

Restore settings to factory default set

Keep〖P〗and〖▲〗depressed simultaneously for 3 seconds, “UnL” displays. Then press〖▼〗 twice, all parameter settings will restore to factory default set value.

Attention

1. Do not connect wiring when power is supplied.
2. Electrical wiring must be manipulated by certified electrician.
3. Read this manual carefully. Connect according to electrical wiring diagram. Wrong connection will damage the device.
4. Do not lay the sensor bundle together with power supply bundle.
5. Avoid working in erosive, wet, strong electrical-magnetic field environment.
6. This device has been checked fully before shipment. The warranty time is one year, damaged by wrong usage, such as wrong connection, is not warranted.
