A Humidity and Temperature Controller
Version A1.01a
Specification
Power supply: 12Vac, or 12Vdc
Input: One humidity and temperature sensor, wire length 1.5 meters, system will be
stable when the wire length is up to 50 meters
Sensor precision: Humidity ±3% RH@25℃; Temperature ±1%@25℃
Setting range: Humidity 0.0 ～ 99.9% RH; Temperature 0.0 ～ 80.0℃
Output: Every output ≤ 7A (250Vac, pure resistance)
Working environment: -10 ～ 45℃; ≤ 90% RH without dew
Power consumption: 2W
Display
When the sensor is not connected well, or fails, display shows “--.-“.
When the temperature output is energized, the up LED “out” is on;
When the humidity output is energized, the bottom LED “out” is on.
Setting Operation
Keep〖S〗depressed for 2 seconds to enter into set status:
The up window displays the parameter code.
The bottom window displays the value of the code.
Press〖S〗to select the code: S01->S02->SC1->S03->S04->SC2.
Press〖▲〗or〖▼〗 to set the value (keep depressed make fast set).
Keep〖S〗depressed for 2 seconds to exit, and the settings are saved.
Note: The status will exit if no key operation for 30 seconds, and the settings will be saved.
Code
Function Set Range Remark Factory Set
SO1 Temperature output energized 0.0 ～ 99.9℃ Set point for on 22.0
SO2 Temperature output de-energized
0.0 ～ 99.9℃ Set point for off
20.0
SC1 Temperature calibration -5.0 ～ 5.0℃ 0.0
SO3 Humidity output energized 0.0 ～ 99.9% RH
Set point for on 10.0
SO4 Humidity output de-energized 0.0 ～ 99.9% RH
Set point for off
20.0
SC2 Humidity calibration -5.0 ～ 5.0% RH
0.0
Control Function
Temperature control
If SO1 = SO2, there will be no temperature control function.
If SO1 < SO2, work in heating mode:
When Troom ≤ SO1, temperature output energized;
When Troom ≥ SO2, temperature output de-energized.
If SO1 > SO2, work in cooling mode:
When Troom ≥ SO1, temperature output energized;
When Troom ≤ SO2, temperature output de-energized.
