Hi there,
I was hoping to get some insight into my underfloor heating system. I am having a problem with one of the zones not coming on at all, and another zone radiating full blast and not being controlled by the thermostat. It then occurred to me that I have very little idea of how the system actually works. If anyone could explain my system to me from the pictures, in fairly simple terms assuming I know very little, that would be very helpful!
I seem to have 8 zones, there are only 6 wall mounted thermostats so I’m guessing two rooms have 2 zones. The labelled pipes aren’t completely useful as they don’t match what is written on the zone actuators above them.
Three things I particularly don’t know are;
1) the blue mixer on the far left appears to mix the flow and return water, it is set to 10 but I don’t know why
2) the black unit on top of the red pump has a grey switch with 3 settings I II and III. It’s set to II.
3) there are little blue tabs on top of the zone actuators. These sometimes seem to pop up, as can be seen in the picture. When that happens the zone actuator feels ‘loose’ on the valve. They then seem to retract again later on. I have been unable to locate any manufacturer docs or instructions.
I would be interested to hear thoughts on how to work out which zone is which, and how to regain control of the zones that I can’t seem to control using the thermostats.
Thanks for your thoughts!
