Automation in detached house: Bartosz recuperation + Viessmann C.H.?

Welcome,

after so many years of supporting the Elektroda forum, I decided to create an account and ask myself a topic that is bothering me.

I am looking for a temperature control system for a detached house based on an air handling unit with recuperation (additionally a cooler or a heater plugged into the system) and central heating, the whole system should work against a set temperature and should be supported either by ventilation or a central furnace. I would like to have access to adjust the temperature in each room separately. I am not interested in separate systems for ventilation and heating.

I assume that in order for the system to function optimally, the operation of the central furnace should be "globalised" and ventilation should be moved to the auxiliary category. As far as I know, Bartosz air handling units and Vissemann central cookers have their own automatics with an output to the intelligent house control system. Will creating a system based on these devices be a difficult feat?
What should I focus on?
What exactly goes into the temperature control system from the central furnace (solenoid valves, temperature sensors, control panels, controller or something else?)
Is there anything else I should anticipate in designing the system?

Greetings
New forum colleague

I have been interested in this topic for a long time, but it is very complex. Perhaps you could start by giving more details, such as the number of temperature measuring points, control of temperatures separately for each room or a total for everything, the number of furnaces (e.g. solid fuel, gas, solar collectors, ground heat exchanger or other solutions), recuperation with built-in cooling or self-made bypass, humidity control, of course, to add because to take away is a very expensive business and finally what price and your skills and time available. I can't hide the fact that I'm happy to help because at work I deal with ventilation, heating, air conditioning and I'm an electronics hobbyist.

I'm afraid that the Colleague will not be able to find such a thing, because you need a project to do it. There is simply no such thing, which by the way often happens in projects for public tenders, as "automation system - 1 kpl."

Ventilation serves to exchange air and not to heat/cool rooms and this is its task, although in the case of a single-family house, the most sensible thing for economic reasons would be for the air handling unit to supply the average setpoint temperature from all rooms it covers. The temperature of the heating medium in this type of installation should be determined based on the heating curve with correction for the temperature conditions in the rooms. The parameters of the factor with low parameters are determined by the technologist (sanitary designer). Room temperature control is carried out locally using appropriate executive devices indicated by the technologist (e.g. an actuator on a radiator), as well as control and measurement devices selected by the automation designer.

The notion of the difficulty of the task depends on whether one has already done something like this or not. For a skilled automaton, full integration with these 2 devices is about 8rh. Viessman will go by LON, so about 2rh max (xify are generally available, the manufacturer has an accurate DTR for the communication gateway), the air handling unit probably by Modbus RTU (I haven't encountered this manufacturer so far in my career), so creating a test frame and matching register addresses, then the target frame with a good DTR is about 6rh. Writing the logic is another matter entirely.

With all due respect to the Colleague, but in my opinion, the Colleague should outsource the project, or at least the design concept and if the Colleague has such skills draw the schematics himself. I doubt that anyone would be willing to answer your questions for free.

The topic has died or you have come up with something.

The topic is from years ago so it has probably died.
The problem itself is contrived and stems from ignorance. Ventilation in a detached house is not for heating, so treating it in this way is a mistake. Ventilation is supposed to provide fresh air in sufficient quantity for the number of inhabitants plus remove moisture from the bathroom. A cooker hood is too much of a philosophy to just plug into the exhaust.
Ventilation that is badly made or malfunctioning can cool a house in winter, but this is no proof of its heating competence. Properly designed and constructed ventilation in a detached house should provide an adequate amount of fresh air and be thermally neutral to the heating system.

Combining heating, ventilation, roller shutters, lighting and whatnot into one functional system from the point of view of presentation and operation is trivial today, and the only problem is the money you have to spend.
