• When using transfer output, add on the communications unit
(E53-AKF).
• You can select the following five data items in the "transfer output
type" parameter (option mode) as the transfer outputs:
Present SP (default), Process value, Manipulated variable (heat),
Manipulated variable (cool), Valve opening
However, note that heating/cooling side manipulated variables can be
output only on standard type controllers, and valve opening can be
output on position-proportional type controllers.
• If the output assignment is changed when either the "manipulated
variable (heat)" or "manipulated variable (cool)" parameter is se-
lected, the factory setting "set point" is returned to.
• These transfer outputs can be scaled according to the settings of the
"transfer output upper limit" and "transfer output lower limit" pa-
rameters before output. Setting of an upper limit value smaller than
the lower limit value is allowed, so reverse scaling can also be carried
out. Also, the scale can be enlarged by the upper- and lower-limit
width specified for each data item. The following example shows scal-
ing of the heating side manipulated variable.
