Uponor zone control module config help.

Good evening. I am having a bit of an issue with a new 3 zone set up. Here is what I have:
*Pic attached
1 - 24v transformer
1- Uponor zone control module
4 - 4 wire actuators
2 - 2 wire thermostat
1 - 3 wire thermostat with floor sensor
1 - single zone single pump relay.
Taco pump.
When I turn power on the pump starts running and never shuts of. The LEDs on the zone control module are solid red. I have cycled the thermostats and the yellow led turns on and off, but the pump doesn't shut down. I'm hoping this is something simple so I posted a picture of my installation, any help would be most appreciated.
Sincerely,
Ded

You can choose to do what you want, but you cannot choose the consequences.
Turn that circulator so the motor is horizontal too , It cannot be vertical and down ever .

Turning the pump now.
I disconnected the actuators from the ZCM and the pump relay remained off, so that a good sign. So that must mean that the actuators are open.
But how do I know if the relays are open or closed?
They don't seem to have an indicator.
Thanks,
Ded

I powered them for over 10 minutes, but if there is no call for heat why are they open?
You may not want to hear this but...it looks like you're in over your head. You may wanna call a HYDRONICS pro.

Nothing is supported because I figured I'd have to change some stuff. I will create permanent supports as soon as it's up and running correctly.
I am really appreciating the advice!
Thanks,
Ded
I did actually read ALL the instructions on ALL of the components but as you said I'm not a pro. The information that seems to be missing for me at least, is when do the freaking actuators actually close? as far as I can tell they are wide open, but as I said if the thermostats aren't calling for heat then why are they remaining open? Shouldn't they be closing at some point in time?
Thanks in advance for the help.
Ded.
Remove one of the red wires to each actuator and it should close. If it does, then you've got a problem with the stat, its wiring or the board. The actuators need to be attached before you energize them.

What have I missed?
Your advice is most appreciated!

If so you are pumping away from the manifold and towards the exp tank?
But your drawing shows the flow arrow going right. Check the flow arrow on them pump body again.
Right track wrong direction?

My thought is that pressure is some how building behind the pump and running back to the return manifold.
If you are not seeing flow, after the ZVs open, most often you have an airlock some where or valve(s) shut off.
Does that manifold have shutoffs under the black plastic caps? Some brands have balance valves on one of the manifolds. Could be closed or shut way down?

For giggles I used all the manual valve operators and isolated each loop. I turned my heat source on my pump off and used pressure from the street to drive each loop. I vented the water at the return into a drain. Each loop performed perfectly.
I also installed a back flow preventer between the boiler and the Taco 007. Bit alas once I turn the pump on, no flow and the return manifold gets pressure locked.
I am so very puzzled.
Any ideas?
I'm not sure what you are describing by "pressure locked" not a hydronic term I'm familiar with?
If line pressure moved all the air out and it runs clear and bubble free, you don't generally have an air problem.

I know there is no flow because the boiler has a flow sensor that kicks the elements on when water start moving. I have checked this with the most miniscule amount of flow.
Second. When I attempt to open the 5th port on the return manifold, it will not open. If I remove the hose and push up on the rubber plunger I get a massive exhaust of water. Far more pressure than I ever let into the system.
It's the darnedest thing.
I'll bi pass the prv today.
Thanks again!
I really want to thank all involved in this thread. I feel like this little project and the input from the professionals here have increased my capacity!
Now all I have to do is add the proper supports....
I'll post a picture of the final product in a couple days.
Thanks,
Ded

I am so incredibly happy with this system. So quiet and the heat is simply awesome.
