9.1

Introduction

A distinction is made between:

General errors

General errors are not visible on the control. General errors are:

-Gas smell

-Insufficient or no hot water

-Water leakage

-Explosive ignition.

The manual includes a table with general errors (9.2 “Troubleshooting table for general errors”).

Errors visible on the control

The control displays errors by means of an indicator LED. This LED is visible through the inspection window in the cover plate of the control. Different errors are indicated by different flashing patterns of the LED.

The different errors are divided into three groups:

-SOFT LOCKOUT (SL)

The control automatically resets after 60 minutes.

-SOFT LOCKOUT/HARD LOCKOUT (SL3)

The control automatically resets after 60 minutes with a maximum of three attempts. If the burner still has not been ignited, contact the installation engineer.

-SELF CLEARING (SC)

These errors disappear automatically if the cause of the error is no longer present. The device will automatically start up then.

The manual includes a table with Error messages that the control displays

(9.3 “Troubleshooting table for errors visible on the control”). The electronic control can be reset by maximally turning the thermostat counterclockwise and returning it again to its original position.
