Control Output
Control output (OUTPUT1) selects the output type among the current output, voltage pulse
output, and relay contact output signal.
Preset output value is output when the operation is stopped by key operation or contact
input, which takes priority over the manual operation.
Each function can be set by the following parameters.

Contact Output
Alarm 1 is output via DO1 (contact output 1).
Alarm 2 is output via DO2 (contact output 2).
Alarm 3 is output via DO3 (contact output 3). When cooling-side output is set for relay
output in heating/cooling control, cooling-side output is output via DO3. Alarm 3 is output
via DO5.
Alarm 4 is output via DO4 (contact output 4). When cooling-side output is set for transistor
output in heating/cooling control, cooling-side output is output via DO4. Alarm 4 is output
via DO6.
Alarm 3 is output via DO5 (contact output 5).
Alarm 4 is output via DO6 (contact output 6).
No function is assigned to DO7 (contact output 7).
