When manual operation is active, the relays are no longer energized and deenergized

according to the control state, but are set to a predefined manual operation state

depending on their function.

The burner relay energized in manual control can be deenergized by the electronic

temperature controller (TR).

After manual control has been activated, a change to the basic display must be made.

There, the maintenance / special mode symbol

appears.

Press the info button to switch to info display “Manual mode“, where the setpoint can be

adjusted.

The chimney sweep function is activated by a short press (maximum 3 seconds) on the

chimney sweep button. This function produces the operating state required to make

emission measurements (flue gas).

The SLT test (SLT = safety limit thermostat) is activated by a long press (longer than 3

seconds) on the chimney sweep button. The button must be kept depressed during the

entire test. If released, the test will be aborted. The SLT test is shown on the display.

The test may only be made by qualified staff since the boiler temperature will be raised

above the maximum limits.
