Operation

Cleaning

- this option is used when manually cleaning the boiler; flue gas fan is working according set rpms and for set time

Cleaning - entering this option, flue gas fan start to work according to set rpms for set time

Time - set the working time of the flue gas fan

Fan - set the working rpms of the flue gas fan

History

- list of all errors/warnings/informations that appeared with time and date when they happend

DHW

- this option is used for setting DHW

DHW - enable/disable DHW

Schedule - enable/disable DHW schedule

Table - set DHW schedule time table

Fan adjustment

- this option is used to set flue gas fan rpm on boiler working stages

- fan can be adjusted for 4 stages:

S-stage (ignition), C-stage (stabilisation), D-1-stage/D-2-stage (working stages-one setting)

- NOTE: factory setting depends of boiler power; example below is for 25 kW

IMPORTANT: flue gas fan rpm must be increased above factory setting when firing with wood with more than

30% moisture or when flue gas connection and chimney doesn’t provide enough underpressure on nominal

boiler power. Flue gas fan rpm increase must be done according individual situation so flue gas temp. would

not achieve to high value, but enough that boiler works correctly.

Pump protection

- this option is used to enable/disable pump protection option (default: enabled) - if any pump/mixing valve actuator is not

worked in 48 h, regulation starts it for 60 sec.

flue gas fan rpm is shown as % in relation to max. fan speed

- FLUE GAS TEMP. SENSOR - DISABLED - boiler will work in INTERVENTION WORK without flue gas temperature

control (use only in emergency because there isn’t flue gas fan protection against to high temp.), flue gas temp. is NOT

shown on screen

- DHW TANK SENSOR - DISABLED - DHW pump (P2) will work allways, DHW temp. is NOT shown on screen

- ACCUMULATION TANK UPPER SENSOR - DISABLED - boiler will work in INTERVENTION WORK without upper

accumulation tank sensor control, pump P1 will work without control by upper accumulation tank temperature,
