Hello, my name is ***** ***** I look forward to helping you!
Do you have zone valves.
Does each zone have a pump and solenoid valve?
Can I see a picture of the manifolds from a distant and also the pump controller?
Just got them please wait a sec while I review
The pump is NOT the issue, the controller is not recognizing the thermostats signal. Or the thermostat is bad
Can you feel the pump running? or just water flowing through it?
Water running through a pump is totally normal. unless you have a zone valve closed
I can explain this better over the phone. If that doesn't work for you please wait while I type up my explanation
It's okay =)
Each one of these thermostat wires control a zone pump (wait there is more)
These are your secondary loop zone pumps that are controlled by the stats ( still more)
Secondary loop pumps
This is your PRIMARY pump, it is controlled by a temp controller and should always be maintaining heat when in heat mode, If it's pumping and a zone valve is open then it with push water through another secondary pump until the zone valve is closed
The thermostats control the secondary pumps, but water can still flow through them if zone valves are open
Does that make sense or do you have questions?
Modern systems are. They turn on seconds before the pump. I didn't see electronically controlled valves in your pictures though
This may help
Yes, but they don't prevent water from flowing through them when off.
Sure, but I'm a plumber by day so my availability is usually evenings.
Water runs the path of least resistance so I bet water is NOT going through the whole loop
