Power up Display
The model (ZL-6231A) and software version (Version 2.0) will display after power supplied:

Operation

Set Set-Point (Factory Default Setting = 37.8℃)

• Keep〖S〗depressed for 3 seconds to enter into the status. The current set-point value displays.
• Press〖▲〗or〖▼〗to set the value (keeping depressed can fast set).
• Press〖S〗to exit, and save the settings.
  The status will exit, and the setting will not be saved if no key operation within 30 seconds.

Set System Parameters

• Keep〖P〗depressed for 3 seconds, digits show “—0”.
• Press〖▼〗to select the digit of the password, press〖▲〗to set the value of the digit.
• Press〖S〗to confirm: If the password is correct, enter into the parameter setting status, else display “Err”, and exit.

Set in parameter setting status:

• Press〖▲〗or〖▼〗to select the parameter code (see parameter code table below).
• Press〖S〗to display the value of the code. Press〖▲〗or〖▼〗to set the value. Press〖S〗to return to parameter code selection.
• Keep〖P〗depressed for 3 seconds to exit, and save the settings.
  The status will exit, and the settings will not be saved if no key operation for 30 seconds.

Note:

• U46 will be saved to permanent memory once every hour.
• Limit Protection:
  • Troom: Temperature of the room.
  • SP: Temperature set point.
• When U44 = 2:
  If Troom ≥ SP + U54 in heating mode (U90 = HE), or if Troom ≤ SP – U55 in cooling mode (U90 = CO), then R2 will be energized.

Control

• Cooling Control (U90 = C0)

  • If Troom ≥ Set-point + U22, and Temp. Output has been de-energized for U10, then Temp. Output energized.
  • If Troom ≤ Set-point, then Temp. Output de-energized.

• Heating Control (U90 = HE)

  • If Troom ≤ Set-point – U22, then Temp. Output energized.
  • If Troom ≥ Set-point, then Temp. Output de-energized.

• Temp. Output Load Delay Protection (only for cooling control)

  • After power supplied, Temp. Output could be energized after U10;
  • After Temp. Output de-energized, it could be energized again after U10.

• Buzzer Function
  Every key press, there will be a short beep. Every confirmation key press, there will be a long beep. Every error operation, there will be three short beeps.
  When there is failure, or external warning input: If U62 = 0, no buzzing warning. If U62 = 1, there will be continuous buzzing of warning.
  The waring will stop, if press〖P〗, or warning condition disappears.

• External Warning Input

  • NO: normal open. If open, no warning; if closed, warning.
  • NC: normal close. If closed, no warning; if open, warning.
  • Locked: Warning keeps after the external warning disappeared. Press〖P〗 to stop warning.
  • Unlocked: Warning stops after the external warning disappeared.
    Note: When there is external warning, the output(s) will be de-energized.

• Sensor Fail
  R1 stop energized.

• Sensor Calibration
  The sensor can be calibrated by U20.

• Restore to Factory Default Settings
  Keep〖P〗and〖▲〗depressed simultaneously for 5 sec, there will be a beep, and “UnL” displays.
  Press〖▼〗twice, there will be a beep, all settings will be restored to factory default settings.

Installation

1st: Insert into drilling hole

Attention

• Wiring work should be manipulated by certified technicians.
• Wrong connection could damage the controller, and the loads. Power supply to terminal 7 and 8 to check the controller. If there is a multimeter, check the outputs, as well as input, by the help of settings.
• Sensor and input signal wires should not be laid together with power supply wire, and even in same pipe.
• Sensor wire is better as short as possible. Not wind the redundant length wire to electrical noise equipment.
• The loads should be within the specification of the controller output driving ability. If using ac/dc module as load, or tungsten lamp, or motor, following the below requirements to avoid surging current damaging or shorten the lifetime of the controller outputs:
  • For ac/dc module as load, the rated current should be no more 1/10th of output specification under pure resistance.
  • For tungsten lamp as load, the rated current should be no more 1/15th of output specification under pure resistance.
  • For motor, the rate current should be no more 1/5th of output specification under pure resistance.
• For example: if drive a 1500W tungsten lamp with 7A (pure resistance spec.) relay, the relay contactor will be burnt immediately.
• Don’t touch inside components.
• Avoid installing controller in the following environment:
  More wet than 90%RH, or easily dew; Vibrating, or will be shocked; Possible sprayed; Under erosive air; Under explosive air.
