• Terminal Cover

L4000FB:Terminal cover for models UT130 and UT150 (1 set)

• Mounting Bracket

L4000FA:Mounting bracket for models UT130 and UT150 (1 piece)

• SP2 lamp (green) 

Lit when SP2 is being used for control operation.

• Alarm 1 (AL1), Alarm 2 (AL2) lamps (red)

AL1: Lit when the alarm 1 is activated.
AL2: Lit when the alarm 2 is activated.

• Output (OUT) display lamps

Lit while control output is being output.
Flashes according to the control output value during timeproportional output or current output. (Flashes slowly when current control output value is small; flashes fast when it is large.)

•  The left lamp is lit in orange during control output of standard type.

 In heating/cooling control, the left lamp lights up in orange when
 the heating-side output is active; while the right lamp lights up in
 green when the cooling-side output is active.

• SET / ENT key (data registering key)

 Registers the data value changed using the data change keys.
 Switches between operating displays or parameter setting displays sequentially.
 Pressing the key for 3 seconds or more in the operating display retrieves the operating parameter setting   display. You can transfer to the setup parameter setting display form the operating parameter setting display.
 Pressing the key for 3 seconds or more in either an operating or setup parameter setting display transfers back to operating display.

• PV display (red)

Indicates PV (measured value) and character information
such as parameter codes and error codes.

• SP display (green)

Indicates SP (target setpoint) and parameter values.

This chapter describes an operating procedure using temperature controllers UT130
and UT150 of standard type with the alarm option as an example. Regarding the
operating procedure for the heating/cooling type controller or for the controller with the
options other than the alarm, confirm whether the some parameters appear or not
referring to the parameter flowchart in “3. NAMES AND FUNCTIONS OF EACH PART /
PARAMETERS.” The operating procedure for UT152/UT155 is the same as that for
UT150.
