• Floating control or closed control can also be selected for the
Position-proportional Control Models. Floating control enables
position-proportional control without a feedback potentiometer.
Parameters can be used to assign the type of data that is output from
each output. For the models with more than one input, assignments
can be made for channels 2 and higher as needed depending on the
number of channels.
Outputs Control/Transfer Output Assignments
Channel 1 control output (heating or open) for control output
OUT1
Channel 1 control output (cooling or close) for control output
OUT2
Channel 1 present set point
OUT3
OUT4 Channel 1 PV
Channel 1 control output (heating or open) for transfer output
Channel 1 control output (cooling or close) for transfer output
Channel 1 valve opening
When control outputs are used, assignments are made automatically
based on the control mode that is set, as explained on the previous
page. No changes are necessary.
When an output is used as a transfer output, assign the data to be
transferred to an unused output.
For outputs with multi-output functionality, specify a pulse voltage
output or a linear current output using the multi-output output type
setting.

Description
Control whereby the MV is increased as the present
value increases
(When the present value (PV) is higher than the set
point (SP), the MV is increased in proportion to the
difference between the PV and the SP.)
Control whereby the MV is decreased as the
present value increases
(When the present value (PV) is lower than the set
point (SP), the MV is increased in proportion to the
difference between the PV and the SP.)
