(21)CH Manual reset amount setting (address: 112H, 142H, 172H, 1A2H)
Standard
Heating-cooling
Set the amount of the proportional band (P) to be moved.
For details on the manual reset function, refer to the following.
Page 155, Section 8.3.4
(a) Setting range
Set the value within the range -1000 to 1000 (-100.0% to 100.0%) of the full scale of the set input range. For
details on the input range, refer to the following.
Page 312, Appendix 3 (5)
The setting range is the same between the standard control and heating-cooling control.
(b) Enabling the setting
Enable the setting contents by either of the following.
• Turning off and on Initial data setting request flag (RY9) while the operations of all channels are stopped
• Turning off and on During operation setting change instruction (RY10)
(c) Default value
The default values are set to 0 (0.0%) in all channels. The default value is the same between the standard
control and the heating-cooling control.
(22)CH AUTO/MAN mode shift (address: 113H, 143H, 173H, 1A3H)
Select whether to calculate the manipulated value (MV) by PID operation or to set it manually by the user.

(b) When AUTO mode is shifted to MAN mode
The following operation is performed.
• The manipulated value (MV) calculated by PID operation is transferred to CH MAN output setting
(address: 114H, 144H, 174H, 1A4H). (For preventing a rapid change of the manipulated value (MV))
• When the shift to the MAN mode is completed, bits of the corresponding channel of MAN mode (address:
601H) are set to MAN mode shift completed (1).
(address: 113H, 143H, 173H, 1A3H)
Set the manipulated value (MV) in MAN mode after confirming completion of the mode shift.

Activates the AUTO mode. The manipulated value (MV) calculated by PID operation is used to calculate the ON time of
the control cycle.
Activates the MAN mode. The manipulated value (MV) written in CH MAN output setting (address: 114H, 144H, 174H,
1A4H) is used to calculate the ON time of the control output cycle.
