Setting

• Keep 〖S 〗depressed for 2 seconds, and enter into setting status:
• The up window displays the parameter code.
• The bottom window displays the value of the code.
• Press〖S 〗to select the code. See the parameter table below for codes.
• Press〖▲ 〗or 〖▼ 〗 to set the value (keeping depressed could 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.

Control

Temperature control

• Heating control
  • When parameter tC = HE, heating control.
  • When temperature ≤ tSP – td, temperature output is energized.
  • When temperature ≥ tSP, temperature output de-energized.
• Cooling control
  • When parameter tC = CO, cooling control.
  • When temperature ≥ tSP + td, temperature output is energized.
  • When temperature ≤ tSP, temperature output de-energized.

Humidity control

• Humidify
  • When parameter HC = H, humidifying control.
  • When humidity ≤ HSP – Hd, humidity output is energized.
  • When humidity ≥ HSP, humidity output de-energized.
• Dehumidify
  • When parameter HC = p, dehumidifying control.
  • When humidity ≥ HSP + Hd, humidity output is energized.
  • When humidity ≤ HSP, humidity output de-energized.

Alarming

• Over temperature alarm
  • When temperature ≥ tSP + tHA, high-temperature alarms, the up window displays ”tHi”.
  • When temperature ≤ tSP – tLA, low-temperature alarms, the up window displays ”tLo”.
• Over wet alarm
  • When humidity ≥ HSP + HHA, high humidity alarms, the bottom window displays ”HHi”.
  • When humidity ≤ HSP – HLA, low humidity alarms, the bottom window displays ”HLo”.
• Calibration
  • The sensed temperature and humidity can be calibrated by set parameter TCA for temperature error,

HCA for humidity error

• Display
  • When the sensor has a problem or is not connected the display ”–.”.
  • When the temperature output is energized, its output lamp is on. When it is de-energized, the lamp is off.
  • When humidity output is energized, its output lamp is on. When it is de-energized, the lamp is off.
• Restore Setting
  • Keep 〖▲ 〗and 〖▼ 〗depressed simultaneously for 2 seconds, and display ”UnL”. Then press 〖▼ 〗3 times, there will be a long beep, and the settings will be restored to factory default settings.
• Attention
  • Install by a certified technician. The outputs are not allowed to drive heavier loads than their specification.
  • The PCB voids are to be exposed to super wet conditions.
