Which resistor should I insert? Problem with the air mass sensor control

I will describe the problem in brief.
I have an IE-26 controller installed in my central heating furnace
and an electronic air mass sensor made by Bolecki.
It works by feeding current from the controller and raises or closes the air damper accordingly.
The problem is that the air mass sensor only works 0 -1 i.e. it opens or closes the flap.
But when I plug a 40W incandescent bulb in parallel into the power supply of the mixer, it works fine (it keeps the air flap so that it maintains the set temperature).
My question is what resistor or resistor + capacitor set should I plug in to get a resistance of 20 - 40W and that they don't heat up too much? Or any other solution?

Could you be specific, for example, about such and such a resistor, because, say, 10 resistors is a bit unprofessional, I'd prefer one

Yes, but then the boiler room is lit non-stop, which is exactly what I don't want

And I would ask at Bolecki. In the forum or by email. Maybe they had a case like that. Maybe it would be enough to insert some kind of filter at the input.
After all, it's pointless to insert a constant load of 40W.

Problem solved. It was enough to cut off the leg of such a resistor in the controller and measurer and the problem disappeared
