Inputting Parameters
The Temperature Controller has three display levels, 0, 1, and 2, in which only specific parameters can be set. Level 0 is the initial and is auto-
matically entered at power application. To change the mode to set or change a different group of parameters, hold down the Level Key for 2
seconds minimum. The display level mode changes as shown below. Actual displays vary with models and switch settings. If a display does not
appear as expected, check your switch settings.

Note:
1. Not displayed in automatic output mode. “m––– ” will be
displayed if a potentiometer is not connected.
2. Not displayed in manual output mode. “a––– ” will be dis-
played if a potentiometer is not connected.
3. Not displayed when the alarm is disabled (SW203 set to
0 or 9).
4. Not displayed when the input shift display is disabled
(SW201, pin 3 OFF).
5. Not displayed when PID display is disabled (SW201, pin
6 OFF).
Main Setting
The set point can be changed with the Up and Down Keys.
Valve Travel
The value travel can be monitored. If a potentiometer is not con-
nected, the display will show “a––– ” for automatic and “m––– ” for
manual operation. While “m ” is displayed in manual output mode,
the Up Key will turn ON the OPEN output and the Down Key will turn
ON the CLOSE output.
Selecting the Output Mode
The A/M Key can be pressed for one second or longer to change
between the automatic and manual output modes. The balance-
less-bumpless function will operate to prevent the output from
changing abruptly.
Automatic Output Mode
In automatic output mode, the control will function automatically.
When the A/M Key is pressed and the automatic output mode is first
entered, displays like the following will appear (display level 0).
PV
123 Process value
SV
80 Main setting
Manual Output Mode
In manual output mode, the controller can be operated with the Up
and Down Keys. The Up Key will turn the OPEN output ON and light
the OPEN indicator. The Down Key will turn ON the CLOSE output
and light the CLOSE indicator.
When the A/M Key is pressed and the manual output mode is first
entered, displays like the following will appear (display level 0).
PV
123 Process value
SV
m 80 Valve position (%)
The MANU indicator will light and remain lit until the automatic out-
put mode is returned to.
