3. Operations
This chapter describes key entries for operating the controller. For operations using
external contact inputs, see “1.5 Terminal Wiring Diagrams.” If you cannot remem-
ber how to carry out an operation during setting, press the
S E T / E N T
key for more than 3
seconds. This brings you to the display (operating display) that appears at power-
on.
3.1 Monitoring-purpose Operating Displays
Available during Operation
The monitoring-purpose operating displays available during operation are roughly classi-
fied into two groups depending on the types of controller and control output. One group is
operating displays for standard and position proportional controllers and the other group is
operating displays for a heating/cooling controller.
