HI
@R-CAD do you have a post on what you used for all the different components .
Doing a self build our self and looking into UFH and MVHR. Have you got it to play nice with Loxone.
I've not made a post on the full install, but happy to answer any questions.
I've used Loxone Actuators on someone elses UFH manifolds, and have Loxone Touch Tree switches in most rooms that give a temp and humidity reading, as well as Loxone motion sensors in most areas/rooms that provide a brightness reading as well as detecting motion.
From the ASHP I have heating and cooling*** (delivered via UFH & MVHR), and I have around 20 configurable zones that you set your desired temperature to, which could be different temps at different times of the day, and Loxone learns how long it takes for a given zone to heat or cool and then tells the ASHP what to do and opens up the necessary actuators to delivery the temps to the schedule.
***it can only deliver heating or cooling at a time, ie. it can't heat one zone and cool another at the same time - this is a restriction in the ASHP rather than Loxone.
In truth, while the system is configured to be able to do this, I have all beds set to one temp and all living areas set to another, and they are at the same temp 24 hours a day since my house requires very little heat input.
But I do have quite a lot of glazing on my South-East and South-West elevations and use Loxone to control the solar gain. ie. leave the external blinds open until the house is just over target and then angle the slats to cut out any further solar gain.
If the house starts to overheat in spring/summer/autumn, due to solar gain, then Loxone uses passive measures first: blinds down, roof vents open (if not raining), MVHR to summer bypass and if external temp is lower than internal temp puts the MVHR on to boost to dump heat (very effective at night). If with these measure in place the temp is still increasing then it goes to active measures and uses the ASHP to cool the floor and chill the air coming in through the MVHR. (The MVHR doesn't shift enough air to make a big difference in temp, but can be used to trim the temp. It can deliver around 2.5kW of heat or cool to the house)
The ASHP, UFH, MVHR, Blinds, Roof vents are all from different 3rd party companies, with different communication requirements and Loxone controls them all and keeps them in sequence. Without Loxone each would have it's own controllers and sensors and none of them would be talking to each other.
The communication with the ASHP (Mod Bus) and the MVHR (IP) was beyond my technical knowledge, so I did use a professional installer to configure the communication. But once the communication is set up I've been able to reconfigure it myself when needed. But changing temps and timings is simply for anyone in the family to do via the App/Browser/touchscreen.
I'm not sure that could be said for any other building management system. My understanding is they all require bespoke programming, and you need to get the programmers back in to reconfigure anything. A friend of a friend has a Crestron and Lutron system and his programming costs are eye watering.
