Split control calculation
This is a matching box calculation method performed based on the PID calculation result of output 1.
Sprit Direct is used for the cooling control output. Set the output level for the PID calculation result within
the range of 0 to 60%.
Sprit Reverse is used for the heating control output. Set the output level for the PID calculation result
within the range of 40 to 100%.
When "Heating control" is selected for the MODE6 control action setting, the output 2 will perform cooling
control. On the other hand, when "Cooling control" is selected, the output 2 will perform heating control.

Transmission signal output
This function selects one from measured value (PV), setting value (SV), output 1 value (MV1), output 2
value (MV2) and feedback value (MFB) to produce output with analog signal.
For example, you can select PV transmission and connect the analog signal to a recorder to record the
measured value of the instrument in the recorder. The analog signal specification is specified by the
model.

Transmission signal output characteristics
The following shows an example of setting PV transmission and transmission scale.
- Setting condition -
Transmission signal output ························4 to 20mA

* Parallel connection of
controller with sensor signal
of recorder is prohibited.
This enables PV
transmission.
* Parallel connection of controller
with sensor signal of recorder is
prohibited.
This enables PV transmission.
