DURING THE TEST
1. Hold off with the measurement until both the threshold for the
boiler temperature (65 °C) and for the combustion chamber tem-
perature (550 °C) have been exceeded.
✓ The display will then show Measurement enabled.
2. Carry out the measurement.
AFTER THE MEASUREMENT
1. After the chimney sweep test, return to the required operating
mode.
✎ See section “6.6 Changing operating mode” in this chapter.
✓ The chimney sweep test is completed.
6.10 Structure of the menus
On the display of the HDG Compatronic control unit you can read off
information and parameters for the HDG Compact 25 - 80 boiler. All
of the information and parameters necessary to operate the equip-
ment are listed in the following menu structure.
In the display, depending on the configuration of the system and the
equipment installed in the heating system, some parameters may
not be shown as they are possibly not required for the particular hy-
draulic system.
These will only be displayed if the corresponding hydraulic system
was selected during the commissioning process.
AVAILABLE LEVELS
The control of the heating system is divided into four levels. Each
level contains different information and parameters.
At the start of the measurement, the boiler temperature should not
exceed 75 °C. If there is an accumulator, its temperature should also
not exceed 60 °C. Ensure there is sufficient heating demand placed
on the heating circuit.
Having the measurement repeated by the combustion engineer or
by HDG specialists will incur charges.
If you do not change the operating mode within 45 minutes, the
heating system will automatically return to the previous operating
mode.
