Function 11 : Hysteresis type
According to selection of Hysteresis type in ON/OFF control, ON/OFF turning point is as follows:
ex) HYS.t: Cntr(center)
- Hysteresis type sets center,
• In heating control, OFF point is SV + HYS/2 and ON point is SV - HYS/2.
• In cooling control, OFF point is SV - HYS/2 and ON point is SV + HYS/2.

Function 12 : Manual output function
If you want to use manual output function, there are 2 ways as follows.
1. Select ON in manual output(MV.Mo) of control group(G.CtL) and current control output amount
converts manual output value. When choose OFF, manual output converts back to auto-output
control.
2. Select manual output function in hot-key(Hk.SL) of control group(G.CtL) and press
hot-key(SET+UP) for 3 seconds at the front panel for manual control output.
When press hot-key(SET+UP)again, manual output converts back to auto-output control.
Note: When auto-tuning(AT) runs, 'AT indicator' flashes at the front panel.
(When manual output is 'ON', 'AT indicator' lights on steady at the front panel.)
Output amount for manual output is adjusted by UP and DOWN key in monitor MV screen.
Function 13 : Factory reset function
This function is used for parameter values to revert to initial setting values.
1 . Select factory reset function (PArA) in control group (G.CtL).
2 . If "1" is selected, input for password will be prompt.
3 . Entering correct password [1304] will reset parameter values to initial setting values and controller
4. In case of input wrong password for 3 times, display will go back to operation screen.
Function 14 : Quick menu setting
HYS : 10 ℃
This function is for selecting frequently used parameters quickly and easily.
1 . Press SET+DOWN key for 3 sec. it will go to the quick menu setting.
2 . SV1, SV2, AL-1, AL-2 values can be set from quick set menu.
3 . Press SET key for 3 sec. to go back to operation screen.
Time
Function 15 : HOT key
Time This function is for activating/deactivating most frequently used function on operation screen.
1 . Press SET+UP key for 3 sec. to activate hot-key function.
2 . Press SET+UP key for 3 sec. again to deactivate hot-key function.
One of the following two functions can be assigned as hot-key function from the hot-key
select menu (HKSL) in control group (G.CtL) .
1 . AT (Auto-tuning) : ON / OFF
2 . A-M : Automatic control / Manual control
