Wired-Or thermostats

Post by pulleyj »

I have a BMPlus 6000 Ultra-Zone control panel with 5 zones.
I would like to have either of 3 thermostats operate all corresponding 3 zone dampers.
The dampers are MA-URD.
If this is possible, how can it be done?

I don't quite understand what your exact question is.
Can you rephrase your question?

I have 5 zones in my ranch house.
I had someone give me an estimate on installing a new geothermal heat pump.
While evaluating my current system, he said I should not have 5 zones because it
was over-working my system and that my duct work was not correct.
I have a by-pass damper which he said was a bad idea. He said I should have only
3 zones at the most and that the by-pass damper was to correct the poor duct design.
Basically, he said I should have more ducts active per zone than I currently have.

So, I was wondering if there was an easy way to open more ducts when one of the
zones was activated. I was hoping to avoid any major work by activating more than
one damper instead of re-doing the current duct work/dampers.

For instance, in the main living area of my house there are 2 thermostats - one in the
family room and one in the living room. Say the family room thermostat is calling for
cool and the living room thermostat is not. Is it possible/practical to tie the
two thermostats together so that both zone dampers will open?

What you could to is abandon one of your thermostats and tie both your living room and family room area dampers to the same zone motor terminal block.
Set up this way, when your thermostat calls, both zone dampers will open.
Does this seem similar to the solution you are looking for?
