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.

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.”
