• When the control output cycle unit has been changed, the control output cycle setting, heating control
output cycle setting, and cooling control output cycle setting are overwritten with their default values. A set
value discrepancy error (control output cycle unit selection setting) (error code: 1920H) occurs right after the
control output cycle unit selection setting change. To clear the error, turn from OFF to ON 'Setting value
backup command' (Y8) and register the parameter after the change in the non-volatile memory.
• A set value discrepancy error (sampling cycle) (error code: 1930H) occurs right after the sampling cycle
change. To clear the error, turn from OFF to ON 'Setting value backup command' (Y8) and register the
parameter after the change in the non-volatile memory.
