I have an installed Wirsbo system with four different zones that heats
our whole house. I am very happy with this system, but have had some
trouble balancing distribution between and within zones. As I walk
through the house, I step from a too-warm floor section to a too-cool
floor section, even though the thermostats are all set identically.
Can anyone offer tuning tips or point me to documentation about this
process? I would rather understand how to do this myself rather than
call the heating contractor out for a visit.
Let's see, you did it yourself, right? As I work with DIY homeowners,
Did you read the CDAM? It says so right there, on page 71.
How did you hook it up? Did you run it right off the boiler? What control
strategy did you use?
Where'd you buy the tubing?
I'd call them at 800 321 4739 and ask if they can send you the
information you're looking for.
Or, you can make an information request from them at:
First, it may not be tuning. If the insulation is poor under the cooler
section, that may be the reason.
Second, to tune it you need to have the cool sections running full bore,
and then slow down the warmer ones. IOW, if you have one cool room, you
need to slow all the others down to warm the cool one up. I need to slow
down my master bedroom a bit because that is where the stat is and it
runs warmer than some of the other rooms.
