My Venmar E15 ECM HRV (heat recovery ventilator) isn't working. I think the problem is in its wall control. I have a new one, and a replacement for the circuit board in the HRV, should it need that, but I am not an electrician and I would probably mess something up trying to DIY this.
I would also like to talk to someone who knows how this HRV works about simplifying its controls: a simple on-off and high-low switches might suit the way I use it better. If you know how to help me with this I'd appreciate your call.
