• For transfer output, use an output that is not used for control output.
• Transfer output can be used to output one of the following 6 types of
data as selected in "Control / Transfer output assignment". For more
information, see "8.11 Control initial setting 2 level (l.2) Control /
Transfer output 1 to 4 assignment (P.8-46).
SP, ramp SP, PV, MV (heat), MV (cool), valve opening
Note that the heating and cooling MVs can only be output from a
standard type, and the valve opening can only be output from a
position proportional type with a potentiometer connected.

• Scaling of the output value can be performed using "Transfer output
upper limit" and "Transfer output lower limit". The upper-limit can be
set to a smaller value than the lower limit to perform reverse scaling.
The scale can be enlarged using the width between the upper-and
lower-limits specified in the setting data. The following diagram
shows an example of scaling the heating MV.
