Function Description
PV).
0: heating action
PID forward/
(E=SV-PV)
reverse
1: cooling action
direction
(E=PV-SV）
The error value (E)
is the difference
between the SV
and the PV. When
this setting is 0,
the function is not
enabled. When
this setting is
enabled, the CPU
module checks
whether the
present difference
is less than the
Range within
absolute value of
which the
ERR_DBW, and it
error value is
checks whether
counted as 0
the present
difference meets
the cross status
condition. If the
present difference
is less than the
absolute value of
ERR_DBW and it
meets the cross
status condition,
the present error is
counted as 0, and
