Check measurement
The GasSolarUnit/GasCompactUnit is
equipped with a simply selected automatic
function for check measurements (e.g.
emissions test).
These are described in the abridged operating
instructions and in detail in the separate
“Operating instructions for heating contractors
“ROTEX control unit” (see also the schematic
diagram in Fig. 9.2).
Pressing the Manual key (pos. 13 in Fig.
4.1.1) ramps up the boiler to its maximum
boiler water temperature for 20 min. Pressing
the key a second time during that runtime
switches the burner back to minimum load.
The runtime for this setting will start again at
20 minutes. Pressing the key again during the
20 min. period terminates the emission test.
