CH1 Manual reset amount setting
Set the travel amount of the proportional band (P). For details on the manual reset function, refer to the following:

■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory area name
CH Manual reset amount setting
CH Manual reset amount setting (in the Q compatible mode)
■Setting range
Set a value within the range of -1000 to 1000 (-100.0 to 100.0%).
The same setting range is applied to the standard control and heating-cooling control.
■Default value
The default value is 0 (0.0%). The same default value is applied to the standard control and the heating-cooling control.
CH1 AUTO/MAN mode shift
Select the value calculated by a PID operation as the manipulated value (MV) or set the manipulated value (MV) manually.

■When shifting the mode from the AUTO mode to the MAN mode
Execute the following operations:
• The manipulated value (MV) calculated by a PID operation is transferred to 'CH1 MAN output setting' (Un\G519).
(Operation to prevent a rapid change of the manipulated value (MV))
• After the mode is switched to the MAN mode, bits of 'MAN mode shift completion flag' (Un\G44) corresponding to the
channels are set to Shift to MAN mode completed (1).
AUTO/MAN mode
'CH1 AUTO/MAN mode shift' (Un\G518)
'MAN mode shift completion flag' (Un\G44)
Set the manipulated value (MV) in the MAN mode after checking the completion of the mode shift processing.

Description
The AUTO (automatic) mode is activated. The manipulated value (MV) calculated by a PID operation is used for the
calculation of the ON time of the control cycle.
The MAN (manual) mode is activated. The manipulated value (MV) written in 'CH1 MAN output setting' (Un\G519) is used for
the calculation of the ON time of the control output cycle.
