When manual control is active, the relays are no longer energized and deenergized
according to the control state, but are set to a predefined manual operating state
depending on their function.

temperature controller (TR).
After manual control has been activated, a change to the basic display must be made.

The chimney sweep function is activated by a short press (maximum 3 seconds) on the
chimney sweep button. It produces the operating state required for making 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.
