3. MONITOR screen explaining
When users have already setup program, the monitor screen provide users to (RUN),(STOP),(ADVANCE),
(PAUSE),(HOLD) the programs. The users can see three areas, It includes Low room, High room,
Test room. Also can see the present output percent ratio and more the others details.
4. MODE SET Screen explaining
When users have setup the programs function, MODE SET screen provide the others detail settings for
users. Such as execute reserved start time or not, execute reserved stand by time or not, execute return
ambient temperature or not, power down( Black out resume)or not. Remember to choose execute
patterns(programs).
4.1 Choose execute pattern
Before setup mode set , must choose execute pattern, such as 2 zone, 3 zone, step, link. then continue
next setup.
9

4.2 Execute reserved start time or not
There have two execute methods in reserved start time.
RUN: Normal setting, give up reserved start time.
Ready: Reserved start time, Month/Day/Hour/Minute.
4.3 Execute reserved stand by time or not
When a program have finished running , users can choose TEST END or STANBY . If a user choose
TEST END ,when a program have finish running, then a program will test end. If a users choose
STANBY , when a program have finish running, then a program will stand by, after stand by time,
a program will turn off. Time setup range:00hr00min~99hr59min.
10

4.4 Execute return ambient tempature or not
When a program have finished running , depend on a user demand, back to ambient temp or not.
Ambient temp setup range:0~50˚C.Factory default:15~35˚C.
4.5 Execute Power down(Black out resume) or not
When a controller is running a program, because unknown factors then a controller power off, after
restarting, there are three situations can be selected.
STOP: When users turn on the power, appear RST button, then push it. The program is stop.
COLD: When users turn on the power, the system give up normal process, return back to the first
process.
HOT: When users turn on the power, a controller continue the present process.
11

5. DEFROST screen explaining
Setup auto defrost function, defrost temperature, defrost time, end defrost.
Notice: Auto defrosts or manual defrost is only exist in high temp.
5.1 Auto defrost function
Cycle: Calculate auto defrost by cycle. Time : Calculate auto defrost by time. Off : Turn off auto defrost
function. Suggest auto defrost select cycle will be great, 120 cycle is maximum, if cycles is too more,
low temp performance will be bad.
5.2 Defrost temperature
Setup defrost temperature more high, it need more time to finish defrost. Suggest temperature will
be 10˚C.
12

5.3 Defrost time
When defrosts the temperature to arrive, defrosts the delay time only then to start to calculate, generally
suggested that the time is 5~10 minutes.
5.4 End defrost
Users may suppose when the settled experiment ended, whether needs once more to carry out one
time to defrost the movement.
13
5.5 Manual defrost
In the low temperature area, if users have a demand, they can choose manual defrost, this screen only exist when
a program is running.

6. PROGRAM screen explaining
There are four kinds of program to be selected. such as 2Zones,3Zones,Step,Link.
Program screen
6.1 Special items for Programs setup
6.1.1 When a program is running, get into stored program can’t change a running program(Red color).
6.1.2 After setup a new program, remember back to MODE SET screen, setup all of function that you need.
Then back to Program screen to push (RUN) button. If you neglect MODE SET screen,
push(RUN)button directly, it’s also fine, all setup according to your demand.

6.2.4 Link Pattern(Program)
Link pattern combine 2 zone, 3zone,step.It provide users more flexibility.
15

6.3 2 Zone pattern set
When test condition between heating and cooling.
2Zone setup
6.3.1 Test name type in
Users can type in any test name that they like. Test name make a program easy to remember.
6.3.2 Patterns number
Choose Patten number before others setup, because pattern number is different, then setup will be
different. Each type of programs can setup 120 programs. so it mean that will be 120 number can be
choose.
16

6.3.3 Patterns cycle
Pattern cycle that mean how many times in running, range limit in 1~9999.
17
6.3.4 Start test from…
Start according to the demand by high temperature or low temperature starts to test.
6.3.5 Wait temp
Setup wait temp in high temp or low temp, when temp achieve wait temp, a controller will get into wait
mode. Range:1~99˚C.

6.3.6 Delete a pattern
Delete a pattern according to user’s demand.
6.3.7 setup a pattern operate condition
Setup pattern operate condition, it include test temperature, spend time, pre wait range,
wait mode on/off,time signal on/off.
6.3.8 Running a pattern
After setup all the others settings, then push RUN button, the screen will jump to MONITOR screen,
start running a program.
18

6.4 3 Zone and Step
Because 3Zone and Step, their setup are the same with 2Zone, so we don’t explain them in here, only
show photos in below.
3Zone setup Step setup
6.5 Link pattern
Link pattern combine 2 zone, 3zone,step.In Link pattern screen have six block, provide users to input
2 zone,3zone,step programs. Test name type in by users.
6.6 Stored pattern
Each type of patterns have their stored patterns, all stored in system memory, users can change or view
patterns that have already be created.

7.TROUBLE HISTORY screen explaining
In the screen, you can see trouble message that ever happen in the past. Trouble message include
trouble name and date/time. When a controller has an error, it will appear a trouble message, and then
users can push RST button back to normal system. That trouble message will save to trouble history.
