Definition of Keys

Instructions of operation

1. When the controller is powered on, 3Display window shows “TH” 5 Display window shows”V01″, the buzzer gives a short beep. After about 2 seconds, it will enter the normal display state.

2. The modification of setting values
   In normal display state, click setting key the two identifiers, “TIME” and “SV” flash at the same time. At this time, the value of the number flashed by the cursor can be modified by shift, increase, decrease keys, and click setting key again to switch to the next group of values. After modification, long press the setting key for 1 second to exit the setting state, or in the fixed mode, continuously click the setting key and modify a group of data and exit. The buzzer will give a short beep to enter the normal display interface, and the parameters will be saved automatically.
   When the controller is running in the program mode, click the setting key, and the value of segments starts to flash. At this time, you can view the setting values of time, temperature, humidity and illuminance under the corresponding number of segments by modifying the value of segments with the increase, decrease keys. And then click the setting key again to modify the setting parameters one by one in the present segment. When the cursor returns to the value of segments and flashes, modify the value of segments again to modify the next segment. When the controller is running in the DAY /NIGHT mode, click the setting key, and the “DAY” identifier will flash. Through the increase, decrease keys, it can be switched, and the “NIGHT” identifier flashes, to view the setting parameters under the day and night. Click the setting key to modify the setting parameters in the day or night mode.

3. To set the number of segments or cycle
   In the non-fixed value mode (see parameter table-1-u1 for details), when the controller stops running, long press the setting key for 3 seconds, the (1) display window displays the “LC” prompt, and the (2) display window displays the password. Modify the password to 3 through the increase, decrease keys to enter the cycle and segment number settings. In the program mode, if the “PRO” prompt flashes, you can set the total operation sections; when you click the setting key, and the “CYC” prompt flashes, you can set the total operation cycles (when the number of cycles is set to 0, the controller always runs). After setting, long press the setting key for 3 seconds to exit the setting and the parameters will be saved automatically. In the day and night mode, there is no total operation sections, only the cycle can be set.

4. Start and stop
   Long press the R / S key U7 (see user parameter TABLE-1 for details) seconds to start the the controller, and the remaining running time will be displayed in (2) display window . When the operation time is over, the controller will stop working, and the buzzer will beep u9 (see user parameter TABLE-1 for details) seconds.(2) display windowwill display “End”, or long press R / S key U7 seconds to stop the controller working and (2) display window will display “oFF”. When the controller is running in program mode and the total number of segments is greater than 1, if the constant temperature and humidity condition (see parameter table-1-u5, U6 for details) is not on, it is necessary to set each segment of time before starting the controller. When the time is all set to 0, the start will fail.

5. Reservation function
   When the value of the reservation function AP (see the user parameter table-7) is set to 1, click the setting key again to set the reservation time, and the unit is minutes. Otherwise, it will directly exit the normal display interface. After the reservation time setting, it is needed to click the R / S key to start the machine. In the reservation timing, you can enter the parameter table again to modify the reservation time, or click the R / S key to stop the controller, and the setting time of running the machine is automatically cleared, which is only valid once.

6. The memory function for power-down By modifying the parameter of power down memory (see “U2” parameter: internal parameter TABLE-1), you can select whether there is memory function for power-down.

Instructions for humidifier

Connect the water inlet hole of the humidifier and the water tank with the hose of the machine, and add water to the water tank of the humidifier at the same time.

Precautions for Use

1. This indicator has pre-set the following functions and protective measures:
2. When the unit is energized for the first time or after the power failure, the compressor can enter into the operating state 1 to 3 minutes later.
3. During the time: from starting the indicator or resetting the temperature to the temperature of the indicator firstly reaches the setting temperature:

  * No dehumidification when heating.
  * No humidification when refrigerating.
3. When the temperature in the indicator is 4 over or under the setting value, the buzzer will beep. The power of the internal heating tube will cut off when the temperature is over 70.

2. In case of the circuit protection act caused by a too long door-opening time, the main power can be cut off.
3. When turning high humidity to low humidity or using the low humidity function from low-temperature area to high-temperature area, please check whether there is any water in the incubator. If there is some, clear it out before use.
4. There shall not be too much culture in the incubator, otherwise the air circulation inside will be affected.
5. Do not impact the unit, or pull the probe in the unit, so as to avoid that it goes out of control.

Wiring connection

1. As shown in the figure, connect pins 1 and 2 of the printer controller and power Cords of the printer (the red are positive) to 5V output terminals of power supply of switch(4 and 5 terminals); 1 and 2 pins of power supply of switch are connected with 220 V AC.
2. Connect the communication ports (A and B) of the matching temperature-control instrument with the communication ports (5 and 6) of the printer controller. Connect PC communication ports (3, 4) with PC. (Note: the communication connecting wires must be placed separately from the strong wires. It is better to use shielded wires to avoid interference.)

Special reminder

1. In order to reduce the interference to the instrument during wiring, please pay attention to the separation of strong current lines (such as power lines and load lines) and weak current lines (communication data lines, etc.).
2. The cables between the printer and the controller must be compressed, otherwise there will be printing errors.
3. The power supply of both the printer and its controller is DC5V, only the power supply at the switch needs to be connected to AC220V. Do not connect the terminals of high voltage power supply and low voltage power supply incorrectly.
4. If the computer monitoring is not needed, communication ports of the PC does not need wiring. Please refer to the printer manual for maintenance and operation of the printer.
