* OT is a setup parameter. You can change the settings of the parameter OT to change the control output type.
See “2. Initial Settings,” for more information.
The control output types, “relay output” and “voltage pulse output” shown in the table above refer to those of time proportional control.
To change the type to a relay output for on-off control, select “Relay Terminals” and change the setpoint of the proportional band to “0.”

Note: The cooling-side control output is selected if 4, 5 or

parameter. The alarm-3 output is not available.
The controller is factory-set to the cooling-side control
output (time proportional PID relay contact output).
* PV retransmission is configured at factory before shipment.
* If 15 V DC loop power supply is used,
retransmission output cannot be used.
* The retransmission output and 15 V DC
loop power supply are not available if
the cooling-side control output is set to
“current output” and “voltage pulse output.”

* This wiring is only possible
for a controller with a heater

Note: External Contact Input
If the power is turned on
when the external contact
input is OFF, the mode
(SP.no or A/M) existing
before the power is turned
off will be continued.

CAUTION
Before carrying out wiring, turn off the power
to the controller and check that cables to be
connected are not alive with a tester or the like
because there is a possibility of electric shock.
