This section shows how to acknowledge and understand possible operation errors .
Errors are indicated by an LED located under the filter reset button . If the LED slowly flashes
orange, it means you need to replace the air filters . See page 29 .
If this LED is red it indicates an operating error . The red LED can indicate three different errors:
LED Red Description
Flashing slowly • Error on the bypass damper
• Error on the internal temperature sensor T3/T4
Flashing rapidly • Error on the fan
• Supply temperature is <+5°C
• External fire alarm is activated
• One of the internal temperature sensors is measuring >70°C
Lights constantly • T1/T2 Temperature sensor is defective
If the LED flashes RED then there is an operating error . The length of the flash corresponds to
an error code with corresponding digits in the left column of the table below, followed by a 5
second break .

Errors are displayed on the HRC3 remote control with an "E" + a number . The error can then
be looked up in the troubleshooting overview and in the control panel's manual for rectifying
errors .
Operating warnings and errors are logged in the controller's memory . Connect a computer
with PC-Tool installed via USB to output detailed information from the logfile .
A restart of the unit (disconnect/connect 230V) will reset the controller and start the unit up
in standard operating mode .
The controller will subsequently check for any errors . This can take up to 15 minutes .
