I don't need the questions answered any more. I needed more air because the heat pump was regularly cutting out on a high pressure switch fault, unless I set the UT-3000 to have a low supply-air-temperature-high-limit. More air helped the problem. But the real source of the problem was that the ...

I need more air than the heat pump calls for, so I'm thinking of wiring the heat pump ...

I also have an ERV with its own controls, which are powered by a 24 volt transformer within the ERV. I want the furnace fan to run when the ERV is on. However, when I ...
