The ERV was installed in the basement using the stand alone configuration. I draw stale air from a return duct that has a register in a large 2 story room (library) on the first floor. The fresh air side supply of the ERV dumps into the basement.
if i am reading this correctly, you are doing something could be very dangerous. By taking air out of your house an not putiing it basck could cause you house to go negative. If the house goes 2 negative you will draw excess air through the envelope thereby defeeting the purpose of the ERV. Alse if you have any gas burning appliances or a fireplace you coild be pulling that air back through the vents. Unless of course the basement is open the rest of the house?

The basement is part of the house. ;-)

Reread sniffdog's post.

yes - the ERV take-ith and give-ith air. I inatalled this per the instructions and there are 3 or 4 different configurations that are possible. I just want to know how to set the ERV control settings.

I struggled with the decision to install this in a standalone configuration. I wanted to tie the ERV into my IAQ tstat controllers which I could easily do with a 110V dry contact activated relay. However, if I do that I would have to bypass the Broan controller and that would only allow me to only turn the ERV on or off, eliminating the automated features in the Broan unit like the Auto Mode with temperature limits.

Any advise on the ERV settings and the operation in extreme tempertaures would be greatly appeciated.

I'm following this thread with interest. We have an Aprilaire ERV going in our new build. We will also have a V.P. IAQ 'stat. No clue yet as to how or if they are going to be integrated.

The ducting is in. The ERV has its own return close to the kitchen. The supply is being pumped into the heat pump's return, if I recall correctly.

The installers put the exterior ducts through the basement wall about ten foot apart. I'll be interested to know how your Broan does with the intake and exhaust going through the same penetration. I'm assuming that is how it is installed from reading the Broan literature.

Yes - that is the other reason I bought the Broan. I only had to make one 6 inch penetration through the house which has a stone veneer on it. It wasn't easy, but I made a perfect 6 inch hole through 1 large piece of stone - got lucky. Doing two of those perfectly would have been too much to expect.

The Broan vent is very interesting. It is an areodynamic design that pushes stale air upward and takes fresh air from below. Seems to work just fine.

My Honeywell Vision Pro IAQ stat has a dry contact relay on the interface module for the Ventilator (it also has relays for a De-humidifier and Humidifier). When you program the stat for the Vent, it turns on the HVAC fan and closes the Vent dry contact. I programmed my 2 IAQ stats for the Vent, but they don't know that the ERV is not attached. I just use the HVAC fans to circulate the fresh air coming into the basement from the ERV to the rest of the house.

To connect the ERV to my HVAC system, I would use a RIB 110V Relay with dry contact activation. I would connect the dry contact inputs on the RIB to the IAQ interface module Vent contacts. When the IAQ Vent dry contact closes, it would thgen activate the RIB relay which would and power up the ERV.

The only problem with this approach is that it would probably mess with the Broan controller timing while in Auto mode. When you put the unit into Auto, it has a 20 minute ON, 40 minute OFF or Recirculate cycle. It also has the tempreture limit settings - the unit runs for a few minutes and sense the external temperature. I fthe limits you set are exceeded, the unit either shuts off or recirculates. When you remove power to the controller (which would happen if I used a RIB relay to periodically provide power to the ERV), I am not sure what would happen to the Broan contoller internal timers - probably a reset.

I was told by the Broan engineers that the unit was designed to run constantly and they recommended the standalone mode. I guess they added the Auto mode becuase there probably are some instances when you don't want the ERV on. For exmple, when it is zero degrees outside, I want all holes into my house plugged up!

Hello sniffdog,

Great products of HVAC system.
I like this products.
Thanks for great sharing.
