my home came with an erv and I'm trying to figure out how to wire it to my ecobee to replace the standard wall controller. The wall controller is 3 wires but the ecobee only take acc plus and minus. I tried do that and the erv doesn't come on. Any help would be greatly appreciated

I would start by checking to see if there is 24V coming from the board and 24V going to the damper motor.

Just checked and have 28v coming off the board and 28v at the harness at the motor.

Twice when testing, when I had unplugged and plugged in the motor the HRV kicked on and was running for a minute then stopped and went back to flashing amber light.

Not sure if the damper was working when the unit came up but I had fan speed control with the button on the unit itself.

During the power up sequence it should operate the damper.  Do you see this happening?

No the damper is not moving during power up sequence.

I am having issues with my Venmar constructo 1.5es.

When I plug it in the green light turns on, changes to solid red for a few minutes then started blinking amber.

Hrv will not run.

Changed the actuator motor but still have the same issue.

Moved the damper by hand, light went out and hrv worked for a new minutes then light started blinking again and it stopped.


Looking for some help on what to check for next.

No visible damage or issue with the transformer or electrical board.

You should see a NEW TOPIC button on the top right of the screen that will let you start a new topic.

Thank you for the response! By the way, what do I need to do to start a new thread? I'm currently job hunting and would like to ask for some interview advice.

The quote reply looks really weird. I wish I could just delete my last post.

To be fair, most immigrants are economic immigrants and have more money than the average Canadian.

He is the owner of the company so he probably has the money.

Right now the average Canadian has a savings of around $852!!

I just got my G2 license and soon after received the email from TSSA about this news that the OP posted. Can a newcomer even make that much in a year?
