ERV with dual ECM motors and good controls

nickzee | Posted in Mechanicals on

Is there anything else besides Zehnder (a bit pricy, but quality supposed to be great) and Recouperator (looks dated and also pricy considering accessories) on the ERV market that would fill below requirements:

1. 2 ECM motors.
2. Economizer or free summer cooling (assuming humidity levels are not crazy)
3. Being able to set it to slight positive pressure (and ramped up speed to get to it while using clothes dryer and wood burning stove)
4. Controls good enough to do #2 and #3, optionally in conjunction with existing 3 zone Prestige IAQ and HZ432 ran system.

    I don't know the answer to your question. GBA readers?

    For free summer cooling in Colorado open up a window. You can get fans that have a set temperature point so they turn off once the room is cooled off enough.

    With respect to positive pressure- that means you are no longer really using the ERV. You might as well get your makeup air elsewhere.
