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.

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).
