15.2 Emissions measurement
The check measurement can be made by a simply selectable automatic
function (see also "Operating Instructions - ROTEX-RoCon BF Con
-
troller").
Ɣ Depress the exit button for at least 5 secs.

Ɣ Select the programme "Emission Measurement" with the rotary
switch.
Ɣ Confirm the changes with a brief push of the rotary switch.
Î The following load types are available for selection:
– Off: Emission measurement is switched off, any Gas condensing
boiler-connected heat generator that is switched on continues to
be regulated normally.
– Base Load: The heat generator is switched on and operated at
the minimum output of the heat generators, irrespective of the set
operating mode.
– Full Load: The heat generator is switched on and operated at the
maximum output of the heat generators, irrespective of the set
operating mode.
Ɣ Select the load type "Full Load" using the rotary switch, but do not
