* Retransmission output 1 is not available if a
15 V DC loop power supply is used.
* If you define the cooling-side output as
current output, retransmission output 1 and
the 15 V DC loop power supply can no longer
be used.
The controller is factory-set to the Single-loop Control
Type. Change the setting of the Control Output Selection
(OT1) parameter to the Heating/Cooling Control.

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.

Heating-side
control output
* The functions of the external contact inputs are the defaults for single-loop heating/cooling control.
To change the functions, reconfigure the Contact Input Registration setup parameter.
Contact rating: 12 V DC, 10 mA or more
Relay contact rating: 240 V AC, 1 A
30 V DC, 1 A (resistance load)
Transistor contact rating: 24 V DC, 50 mA
* The functions of the external contact outputs are the defaults for single-loop
heating/cooling control. To change the functions, reconfigure the Contact Output
Registration setup parameters.
Note: If you define the DO3 output as the cooling-side control output, the DO4 output
serves as the time event 1 output. Inversely, if you define the DO4 output as the
cooling-side control output, the DO3 output serves as the instrument alarm 1 output.

The types of control output, “relay output” and “voltage pulse output” shown in the table above refer to those of time proportional control.
To change to a relay output for on-off control, select “Relay Terminals” and change the setpoint of the proportional band to “0.”
