page 31).
• More effective cooling, once the actuator temperature goes over 10 °C above the target
temperature - LED flashes
• “normal” cooling, if the actuator temperature is within 10 °C above the target temperature -
LED ON
Be aware that the ON/OFF status of the cooler is not shown by means of this lamp.
Control lamp for attention/adjust (red):
This red LED has two purposes.
During the adjust, the LED lights up, if you screw the adjust screw too far. You have to screw it
