Omit the single room rule? Controlled residential ventilation + gas heating, new construction

Yes, I don’t quite understand that right now either, the outside temperature sensor is supposed to reflect the actual outside temperature, preferably protected from wind and sun.....

Maybe to also capture solar inputs? If I measure in the shade and the sun shines into the house all day through 6 huge glass windows, don’t I have more supply temperature than necessary? Or does he mean on the south side but shaded.

The sockets of the ERR can also be wallpapered over and the electrician can be instructed to combine the control loops on a circuit breaker switch (fuse).

In our case, all thermostats are completely open because otherwise the heating cycles too often (now runs at zero degrees outside temperature twice for four hours a day instead of every two to three hours for less than 60 minutes because an ERR opened and thus lowered the return temperature too much).

BTW:
The payback time of a controlled residential ventilation system is about 60 to 100 years.

Controlled residential ventilation is not meant to be cost-effective but to significantly increase living comfort, replace manual airing even during absences, keep pollen outside (my wife is allergic) and allow longer sleep during night shifts in the morning with the window and blinds closed, so as not to wake up after 5 hours at 3000 PPM and with headaches. And it does that, more useful than solar thermal energy by far.

Why in the south? That completely distorts things when the sun is shining on it. Our sensor is in the north.

Yes, I don’t quite understand that either, the outdoor temperature sensor is supposed to reflect the actual outside temperature, ideally protected from wind and sun.....

Now let's all read again what I have written and think about it...

Outdoor temperature controlled regulation, of course with a temperature sensor in the north. Otherwise, it would be pointless.

AND

A thermostat in the south, meaning in a room inside the house that is located in the south as an additional control variable.

A thermostat and a temperature sensor in the outdoor temperature controlled regulation are two fundamentally different things, that should be clear to everyone.

The boxes of the ERR can also be wallpapered over and the electrician can be commissioned to combine the control circuits on a LS switch (circuit breaker).

Why have the boxes drilled at all then? That is also simply a waste of money.

BTW:
The payback period of a controlled residential ventilation system is about 60 to 100 years.

Source?

Have the boxes drilled to satisfy the electrician and the authorities.

The source is not needed - anyone can calculate it themselves.
The heating cost savings through [Kontrollierte-Wohnraumlüftung] amount to at most 1/3 of what you have in a house according to the Energy Saving Ordinance. We currently pay around €55 per month.
Such a system, however, costs more than €10,000, meaning that after at least 545 months or 45.5 years, the system would have broken even.
However, operating and maintenance costs also come into play, which significantly extend the payback period.

Without a doubt, a [Kontrollierte-Wohnraumlüftung] is an incalculable advantage/comfort gain for allergy sufferers or residents of very busy streets!

The rest throws their money out the window.

If two people work 9 hours until 4 pm, who ventilates the house then?
Have you ever slept in the morning in summer in an unventilated, darkened room without air exchange? (3 shifts)

Waking up at 800 PPM instead of 2500-3000 is a blessing for health and not a waste of money.

If two people are working for 9 hours until 4 pm, who ventilates the house then?

And if the refrigerator is closed, do you also leave the light on inside? For reassurance: an empty house can stand for nine hours without forced ventilation without sustaining permanent damage.
