Re: Tekmar 519- Need abit of Advice!
The small Quick Guide sheet that comes with the stat shows how you need to access the menus to change the floor setting. There are user settings, and installer settings
You need to get into the installer settings to make some settings, as shown below press both up and down arrows for 5 seconds to enter installer settings.
You need to go into this menu to tell the stat that a floor sensor in being used. Then the floor setting can be adjusted in the user setting mode.
But I think you still need to hold both arrow buttons for 3 seconds to get into that set floor for adjustment. Just try the various options, you can't really harm the stat.
The floor limit temperature is a good setting to use also, especially with tile.

Re: 3,/4 pex fitting
All pex A tube can accept an expansion fitting Uponor, Rehau, Mr Pex.
Several of the B pex brands now allow cold expansion, Zurn and Sioux Chief.
I would suggest the A pex for expansion.
The expansion fittings do allow for better flow as they do not reduce the ID.

Re: Radiators heating even though their zone pump is off.
Something doesn't look correct here. The mix valve just needs the one circulator on the H port, the upper most circ.
Hard to tell but it looks like the lower pump is also tied to the H port of the mix valve? If so, that will push some flow into that mixed low temperature circuit even when the upper pump is off.

Re: Expensive Check Valve
The checks are rated to 200°F. I don't like the checks close to the pump discharge. I think they get rattled to death in the turbulent conditions there.

Re: Vaillant Oil Boiler
No target wall or kaowool blanket. Its a positive pressure boiler. Make sure its tight.

Yes, Viega Pureflow fittings are what I use when I don't know what kind of PEX I'm working with.
Re: Radiators heating even though their zone pump is off.
that boiler needs to be piped primary secondary. I think Navian offers a header kit option. It may be that silver pipe just below the boiler. If it has a pump in the boiler and is piped without that header or another device you could be getting that unwanted flow

Re: Radiators heating even though their zone pump is off.
it is hard to piece Al. The pics together. Is there a primary loop that the boiler ties into, the boiler having its own circ?
Are there checks in all the circs?
Maybe a drawing would better show the big picture
