5.5.7 Auto/Manual control settings

The  automatic  mode  is  for  the  temperature  to  reach 

SV 

with the 

MV 

value  calculated  by  the  PID  control. 

 

The purpose of the manual mode is for the temperature to reach 

SV 

with a user-defined 

MV 

value.

Note: In manual mode, parameter settings can only be viewed and cannot be changed (except for lock parameters). If the 

[DI-1] digital input terminal function is set to automatic / manual [MAN], the

 

 

button and automatic/manual changeover 

will not work with communication. If the unit is turned on after a power failure or shutdown, the previous mode (automatic 

or manual) will be retained.

It is possible to switch to manual mode during STOP state. It is also possible to switch between automatic / manual

 

mode during adjustment, but automatic tuning will stop if manual control is switched on during automatic tuning. 

If a sensor break alarm occurs in 

[SBA]

 normal mode, the 

MV 

[Er

MV

]

 sensor fault will occur. The 

MV 

settings for 

manual and automatic control can be changed in this state.

Operational priority: Manual control > Stop > Open 

(sensor disconnected)

5.5.7.1 Switching Between Manual/Auto Control

Switching to manual mode for standard control (heating or cooling):

 

– In ‘Normal’ mode, press the

 

 

button, and the device will switch to 

MV 

monitoring mode. The 

SV 

display 

shows 

H

 

(heating control)

 or 

C

 

(cooling control)

 and shows 

MV

, indicating the start of 

MV 

monitoring.

 

–

If any of 

 is pressed during 

MV 

monitoring, the 

MAN

 indicator will turn on, and the lowest 

digit 

(100 digits)

 will flash to indicate that the manual control is active.
