Impossible to operate the Thermo-Chiller with the "RUN/STOP" key on
the operation panel

"REMOTE" light is ON.

It is in the remote operation mode
(DIO mode or SER mode). Set it in
the local mode.

Impossible to operate the Thermo-Chiller

with the "RUN/STOP" key on the

operation panel.

Replace the display board.

See section "4.5.18
Replacement of display board".

"REMOTE" light is ON.

Check if the "REMOTE" light on the operation panel is ON. If it is ON, the Thermo-Chiller is in

the remote operation mode.

Lights on the operation panel or display(s) on the digital display does
not operate

Lights on the operation panel or digital
display(s) on the operation panel does

not show anything.

Replace the display board.

See section "4.5.18
Replacement of display
board".
