What model should I get installed in my home?
For general ventilation, visit: https://www.renewaire.com/how-to-buy/home-ventilation-solutions/
For bathroom exhaust, we recommend 80 CFM for each full bath and 50 CFM for each half bath.
Check with local code to see if the requirements are different in your area.

What should I set my PTL/FM percentage timer to?
First step is to determine what CFM is recommended for your home. Use our calculator.
For EV90-300 units, take the CFM provided by the calculator and divide it by the number in the
model number and then multiply by 100. This is a good base value to keep your percentage time set to year-round. When more ventilation is desired, feel free to increase that value.
Example: For a home with 2400 square feet, 3 bedrooms and an EV130 installed, the calculator says
102 CFM is recommended for the space. (102/130)*100 = 78.46%. So, it’s recommended to set the
percentage timer to 80%.

Where can a residential ERV be installed inside a home?
Our ERVs are internally insulated so they can be installed anywhere in a home, such as a closet, the
basement, the unconditioned crawl space and even the attic. Our residential ERVs cannot be installed where they are exposed to the elements of the outdoors.

What duct size do I run?
Most of our residential duct adaptors are designed for either 6” or 8” ducts. Short duct runs (up to 25’) should work well with 6” while longer runs or higher
CFMs should use 8”. Guidance can be found in the owner’s manual. When in doubt, check with your local HVAC professional.

What is the ABB VFD error, 2021?
The 2021 fault is indicating that the drive has not received an enable signal. The most common reason for this is when the factory installed damper has not achieved its end switch, or the unit has not been provided with an enable.

Why is the variable speed not working with this ECM ERV?
In the electrical box, my unit has:
• a green control board. Make sure the yellow VAR wire is connected to the black COM wire.
• one 10 pin grey terminal block. Make sure there is a connection between terminals 3 and 4 when variable speed desired.
• two 8 pin grey terminal blocks. On the terminal block that has the blue factory wire on terminal 1, make sure there is connection between terminals 2 and 3
when variable speed is desired.
• If the unit has a Carel controller. Give us a call.

Where do I connect the BMS to this Carel controller for BACnet MSTP?
Above the display and to the left you’ll see “J10.” Behind that is “J3.” From the factory, a 6-wire cable is wired to J3 for a remote display but if you are using
BMS, you can remove it and wire your BMS there instead. When wiring, make sure you use the + and – connections and not the vterm, as you can damage the
port.
