current temperature. SV displays setting value of output. If you press the button again, it will return to display mode 2.

4.2.3Automatic Mode/Manual Mode Conversion

Press the AIM (switch) button for 3 seconds to switch to the automatic or manual mode_ If you switch to Iha manual mode, the leftmost side of the SV will di a play M (eg: MO-M100).
In this mode, the output value can be set arbitrarily.

4.2.4 Self.tuning

The factory defaults setting is fuzzy PIO control mode, if need to change to self-tuning mode, then enter into the menu to sal11ct OP (output typ11)- Ctrl (control mode)-AI (Self-tuning).
When in aelf-tuning, the temperature may exceed the setting temperature value (will be different value with different heating system) with On-Off controlling. At this time, there will
be alternate displaying In SV {setting value) and “AT• value until the self- tuning finished.

2) Calibration Displaying SC

And this can be calibrated by setting SC parameter with the range of- 1g9-9g9,:; or’ F. the formula: actual temperature -measuring temperature= SC setting value. This can be set at room temperature status. e.g .• Ensure there is default SC value before calibrating. lfihe actual temperature room temperature is 25°C, but the controlling measuring the 1amparatura at 20°G, than sat SC to so•c as the formula: 2s•c-20°C=s•c

3) Digital Filtering DL

There Is the built-In digital filtering system of the temperature controller. If there Is displaying with the frequent changing temperature values caused by the Input Interference,
this dL can be s11t to gal the stable average value. dL=0-20, Iha largerdL value set, the more stable measuring value will get, but also the slower response. If there is no interference from working environment, then the dL value can be increased gradually until the Instant alteration of the measuring values within 2-5 units. When verifying the instruments, the dL value should be set lo Oto speed up the response.

1) Control Mode Ctrl

PIO: default control mode, can be used al the first using, if there is not the controlling accuracy required. then can be changed to Self-tuning mode .
AT: Self-tuning control mode, can be aetwhen there is not the required controlling accuracy by PID control mode. then the controller will be changed lo on-off controlling. After 2-3 iimes switch actions of the temperature controlling, the microprocessor will analyze period. amplitude and osclllatlon wave caused by on-off control. then calculate lhe optimum parameter value. When in self-tuning. the temperature may exceed the setting temperature. and cause alarm, but therewlll be different value with different heating system. If there is not the required temperature value after self-tuning, then try to change the PID initial value before the self-tuning. or restart the self-tuning_
R: Reset to Factory Defaults, the PIO parameters will be recovered to 1he defaults. After set the R, the self-tuning can be activated by pressing the shift button for more than 3 seconds, same operation as setting the AT to activate the self-tuning. After the self-tuning, Iha controller will be automatically enter Into the PID setting, there Is the optimal parameters saved after the sail-tuning.
ON/OFF: On-Off Control, same as the mechanlcal thermostat, used In general controlling. The heating (cooling) will turn off when the temperature res ch the set-point (set
temperature value+ temperature hysteresis value): and the heating (cooling) will turn on when the temperature drop to the set-point (sat temperature value – temperalur11 hysteresis value)- The smaller hysteresis value sat, the higher aocuraoy the controller control. bu twill cause the more frequent output control.

Control Operation Selection

HEAT: Heating, the factory default with heating sailings_
COOL: Cooling. In cooling element control

5.4Alarm Parameters Setting

diagram

1 )Alarm Mode

Set too: Power on alarm prevent, this will avoid alarming if the room temperature is far lower(higher) than the alarm set value when power on. Ala mi will be activated at the first time when power on the controller, the PV value rise (drop) to the same value as the SV and reach the alarm set value.
Sat as 1: Power on with alarm, alarming will be activated once PV reach alarm set value. If need change the alarm control to heating (cooling) control output, It should be set to
power no alarm prevent mode. 2) HIAL: High llmlt alarm, will be activated when measuring value higher than HIAL value, fomiula: PV>HiAL+DF(Hystaresis value).

LOAL: Low limit alarm, will be activated when measuring value lower than LOAL value, formula: PV<LOAL-DF(Hysteresis value).

DHAL: Positive deviation alarm. alarm will be activated when measuring value higher than DHAL value. formula: PV>DHAL +DF(l-lysleresis value) 5) DL.AL: Negative deviation alarm, alarm will be activated when measuring valu11 highar than DLAL value, formula: PV>DLAL-DF(Hysteresis value). 6) DF: Hysteresis, !llso called temperature hysteresis, selling range 0-200’C or· F(0=0.3’C or’ F). Sat to avoid Iha false operation with frequent on-off from alarm output caused by Iha fluctuation of the Input measuring value. DF hysteresis Is work on both ON/OFF control and alarm setting. Alarm setting example:

1) DISP: Alarm display

ON: The alarm sign will be flashed In PV dlsplaywlndow when alarm Ing.
OFF: No alarm sign in PV display window when alarming.

5.5 PID Parameters Setting

diagram

CU: Control period, sailing range 0-5-120 seconds (0=0-5sacond) , the controlling accuracy will be higher if set Ctl within 4 seconds when in SSR control output. and
normally set Ctl to 20 seoonds when in relay control output. The time ofCII can be shortened if there is not the satisfaction temperature controlling required. But based on the different heating system, the shorter control period will be accordingly shorten the working time of the mechanical switch.

P: Proportional band, to accelerate the response speed and Improve the adjustment accuracy oft he system. The response speed and adjustment accuracy of the system will be
improved by increasing P, but this m11y easily bring Iha overshooting and even the instability to the system. The too small value of P will reduce lhe accuracy, slow the response speed,
delay the adjustment time and even break the static and dynamic performance of the system. 2) I: Integration time. to eliminate the steady-state errors of the system. The larger I value,
the faster the steady-state errors can be eliminated, but too large I value will cause the integral saturation phenomena at initial stage of response process. If I value is loo small, it will be h11rd to eliminate the steady- state errors of the system and ii will also 11ffect the adjustmi:int accuracy of the system. 3) D: Derivative time, to improve the dynamic performance of the system, and its main function is lo restrain deviation’s change in response process. and forec<1stthe devi<1tion change. But too large D value will advance the braking in response process, delay the
adjustment time and will even degrade the anti-Interference performance oft he system.
