Defro Comfort Eco Duo 20 kW: Settings, PID Driver K1PV4, Temps & Excessive Pea Fuel Consumption

Hello

I bought a furnace defro comfort eco duo 20 kw, theoretically theoretically everything is ok. Work on the pid driver k1pv4

that's how temperatures look
boiler's temperature 65
valve temp 50
return temperature 55
domestic hot water temperature 45

this is how the parameters in the service menu look like
min. feeder work = 1
max. feeder operation = 3
min. Feeder gap = 40s.
max. feeder work = 70s.
min. work fan = 13
max. work fan = 25
min. turnover = 80
max. turnover = 310


The problem is that he eats me gigantic amounts of peas, heating surface 200m insulated house. It absorbs about 45kg of peas daily. After talking to defro, I received information that it should burn about 3/4 bags of 25 kg a day. they said that I have to reduce the air in the normal menu and this will help, unfortunately, nothing helps. Of course, they do not even mention the service menu

Maybe some of you have such a stove and share the Settings
Or will someone write how to set the stove correctly?

And a new house, i.e. fresh walls? What temperature do you maintain at home? Sweet peas of any calorie? What does burning look like, are not burnt parts in ash?

Old house insulated with polystyrene 10cm wall thickness is 42cm with foam inside, at home I have about 21-22 degrees, peas 28MJ, you know, when it comes to cigarette butts, it's probably not.

It annoys me a bit because my neighbor has a house of 300m, ca 30kw, we smoke the same peas because together we order and he smokes not the whole bag daily.

From the data you provided, the combustion should actually be about 20 kg at 0 degrees outside. Ceiling insulated?

Honestly, I do not know what could be changed in the settings if the driver is on PID. Should set the fan speed and fuel supply. There is no "left" air that gets into the boiler and cools it by bringing heat into the chimney, the door is all sealed? A clean exchanger when cleaned?

This is a quote from the instructions.

"Va) Air correction
This function is used to adjust the fan power control. The principle of operation of this regulation is based on moving the fan characteristics up or down. If the airflow in the entire control range is too low / high, the ratio must be raised / lowered accordingly so that the fan operates at the right capacity.
In addition, after clicking the Advanced icon, a submenu with the functions: Air correction lower and Air correction upper appears on the screen. The user can adjust the fan speed for both the minimum and maximum boiler power (resulting from the zPID calculation).
Vb) Boiler power
The boiler power function is used to simultaneously regulate the operation of the feeder and the power of the blow. By default, it is set to 100%, however, we can adjust it in the range of 25-110%. With each change made, the upper range of zPID parameters is shifted, both the feeder / feed break time and the blow force. The lower range of parameters remains unchanged. "

Which service option did you suggest to change?

If there are no sinters, it means that the coal burns well.
I would increase the frequency of feeding coal to 2 to 5 sec.
then the stove will reach the set temperature and the fan will slow down (hot fumes will slowly flow in the stove and will not be blown into the chimney).
Do not go too low with the power of the boiler
Work 2-5 sec
Break 40-70 sec
blowing 80-300 rpm
If the flame is calm and intensely yellow, it's ok. If not, the air correction is plus 1% and observation ?
