2) SET area (SV): display the set temperature.
3) Heating lamp: the lamp is on when there is heating output.
4) Fan indicator light: on when there is fan output.
5) TIME: Time display window; display running time or parameter value.
2.5 Button description
6) SET button: used to modify the set value or enter the internal parameter setting, in the parameter setting state, long press the set button for more than 3 seconds to exit.
7) Shift key: used to shift the set value, internal parameters and view the ambient temperature.
8) Decrease key: used to modify the set value, various parameters, or start/stop auto-tuning.
9) Increase key: used to modify the set value, internal parameters, or view the remaining period (X)
10) RUN/STOP: Press for 3 seconds to run or stop the controller.
2.6 Check temperature control accuracy
2.6.1 Select a digital thermometer with a resolution of 0.1℃ that has passed the verification and is within the verification period as a standard and put it into the product work room, and ensure that the sensor temperature sensor is in the geometric center of the work room.
2.6.2 Choose a point within the temperature control range of the product and set the SV temperature control value. When the PV measurement value is equal to the set value, keep it at a constant temperature (1～2) hours or so (depending on the product specifications, the constant temperature time may vary) , Observe that the difference between the actual measured temperature value of the standard thermometer and the measured value displayed by the controller PV should be ≤±0.5℃.

2.3 Operation steps

1) Temperature setting: Press the "SET" button once, the value of the SET window flashes, indicating that the temperature can be set as required, and the required temperature can be set through the "increase", "decrease" and "shift" keys. Press the "SET" key again to return to the standard display mode.
2) Timing function: Press the "SET" button twice, when the time is set to 0, there is no timing function; when the time is set to 0, the controller has a timing function, press the "SET" button, the TIME value flashes, indicating the time can be set as required. Use the "increase", "decrease" and "shift" keys to set the required time value. When the time is up, the TIME window displays the "END" buzzer, and you can press any key to silence it.

Note: ① Each time you modify a parameter, you need to press the "SET" key to confirm and the modification is effective.
② After setting all the parameters, press the "RUN/STOP" key and wait for about 3 seconds to start running.

2.4 Ways to improve the accuracy of temperature control

2.4.1 After the product has been used for a period of time, the temperature control accuracy should be checked according to the method 2.6, if it exceeds ±1℃, it can be corrected according to the following method:
2.4.1.1 Enter the parameter setting, find the symbol.

After the formula is calculated, it shall be modified on the basis of the original PK value at the time of delivery (Note: One correction is not accurate, and the correction can be repeated until it meets).

2.5 Function parameter table

In the standard state, press the SET key and the shift key at the same time for more than 3 seconds, the LCD screen displays the LK code, and you can enter the password setting level interface.
1)When LK is displayed in the output area of the LCD screen, press the plus or minus key or the shift key to make LK=0000, and press the SET key to enter the user parameter level setting.

Symbol	Name	Setting range	Description	Factory set value
Pn	Work group in operation	0～8	For program control only. To set up the work group for operation of meters. When Pn is set as 8, Group 8 is for fixed value control.	Optional
Cy	Number of cycle in a period	0～99	Special parameter for program control. When CY is 0, the meter will run between the work group all the time. When CY is not 0, the meter will shut down automatically after CY in the group.	Optional
dy	Appointment boot selection	0-99：:59	0: No appointment; for other values, after pressing the run key to start, it will automatically delay the dy time and then start the machine.
ut	UV time	0-200 minute	Turn off the UV lamp after ut time, ut=0, turn off the UV lamp manually.	Optional
uS	UV switch	0-1	0: Turn off the UV light 1: Turn on the UV light.	Optional

Table1
2）When LK is displayed in the output area of the LCD screen, set LK=0003, and press the SET key to enter the equipment manufacturer's parameter level setting.The parameter hierarchy menu of the equipment manufacturer is as follows:

Symbol	Name	Setting range	Description	Factory set value
tM	Setup of maxi temperature permissible by the instrument	full range	Stop heating beyond maxi temperature and give alarm.
Po	Boot mode	0～2	①When PO =0, after open the power, the controller in a stopped state, by long press star/stop key is up and running. ②When PO =1, after open the power, the controller will be running. ③When PO =2, running from last power began to run.
AL	Setup of alarm	0～100.0	When the temperature exceeds the value of SP+AL, the alarm light is on and the alarm is output (with HOLD function).
Pb	Zero adjustment (intercept)	-100.0～100.0	When the zero error of the instrument is greater and the full scale error is smaller, the value should be adjusted. As a rule with Pt100 the value is seldom adjusted.
PK	Adjustment of full scale (slope)	-1000～1000 S	When the zero error of the instrument is smaller and the full scale error is greater, the value should be adjusted. PK=4000 × (specified value－actual display value)/actual display value and as a rule with Pt100 the value is adjusted first.
PA	Onboard room temperature sensor correction	-30-30	When there is an error between the on-board room temperature sensor and the actual situation, adjust the value.
2b	The second zero correction	-100-100	When the second channel zero error is large and the full scale error is small, adjust this value. Generally, Pt100 rarely adjusts this value.
2K	Second channel full scale adjustment	-1000～1000	When the zero error of the second channel is small and the full-scale error is large, adjust the value. PK=4000× (mercury thermometer value-display value)/display value, generally Pt100 adjust this value first.

Table 2
※The products have been strictly tested before leaving the factory. When the technical indicators meet the requirements and work normally, no correction is generally required.

2.6. Usage of“ Over-temperature Protector” (optional)

The over temperature protector is a separate protection system. When the temperature controller encounters malfunction and causes temperature out of control and when the temperature in the working room reaches the set value, the overheat protector will cut off the heating and initiate the alarm.
(See Fig. below）working room temperature is lower than set temperature limit The protection system is released after set value and the meter is restored. Cycle repeats until problem is solved.
6.1 Set value is higher or equal to (SV+AL）+ （10～15）℃
6.2 See Fig. 6, Use ＋ and — button for over temperature setting on control panel.
To set desired temperature limit.
Example: SV=130℃, AL=10
Set the over temperature to 150℃.

3. Maintenance and Instructions

1. Upon completion of each operation, first switch off the power. Open the box door and wait till the temperature is cooled down in the box before taking out the cultivated goods.
2. In case of keeping the product idle for a long period of time, it is necessary to clean the product in and out. Pull out the power plug and cover it with the plastic anti-dust cap.
3. If the environment for storage has a high humidity, it is necessary to regularly (about 1 month) power on for heating to dehumidify.
4. Before using it again or in case of any change in technical requirement, it is necessary to check the accuracy of thermal control (see the relevant sections).
5. Except for change of such parameters as SV, AL, Pk, Lk, to change other control parameters, it is necessary to obtain consent from our Service Center or such parameters can be adjusted by the special personages.
