9.1.1. Gas analysis function

The gas analysis function permits to control and analyze the combustion process and set up the gas
supply regulator (see p. 11.2 and p. 11.3, page 25). This function works in the heating mode or combined
mode.
I order to activate gas analysis function, it is necessary to hold the button Кб (RESET) until the symbol
is shown on display. For 15 minutes the boiler will operate at rated power. After this time
passes the boiler automatically returns to the operating mode. In order to switch off the gas analysis
function earlier than in 15 minutes it is necessary to switch off and then switch on the boiler, using
the button К5.

13.4.Boiler's operating logic

Launching the boiler in the heating mode occurs, if the actual heat carrier temperature in the heating
system is 5 °С lower than the set one. Launching the boiler in the DHW mode occurs if there is water flow in
the DHW line.
When switching the boiler on the following prelaunching operations occur:
The electronic board 11 (see p. 13.1 , page 27) checks the presence of voltage;
1)
The pressure sensor 14 actuates. The signal about heat carrier presence in the CH goes to the
2)
electronic board. If the CH is not filled, the boiler launching stops;
The electronic board controls the thermorelay 15 condition and the operability of the temperature
3)
sensors of the CH 16 and DHW 17. If any of the sensors is out of order, this leads to the boiler's
launching cycle's stop;
On the control panel's display the value of the heat carrier's temperature in the CH or in the DHWis
4)
displayed (depending on the operating mode).
If the boiler's launching stops because of failure, the error code is shown on display (see p. 14.1,
page 34).
