Hi everyone,
Quick question about installing a Vanee HRV (60H model 41600) to an Ecobee SmartThermostat.
I currently have a separate remote for HRV. Am I right that I just need to plug the G and B wires into the ACC + and - wires of the Ecobee and forget about the Y and R wires? The 4 wires from my remote plug directly into the HRV.

From what I understand I'll lose the ability to have the HRV run on low if I do that, right? Am I right that it will also run on high every time, and run every time the furnace fan comes on, functionally interlocking it?
Thanks in advance!
I know for sure connecting the Vanee 65H B and G to the Ecobee ACC terminals will work but apparently we should use the OL and OC HRV terminals instead of the B and G. OL and OC are the dry contacts intended to be used.
I believe you are stuck using high speed only.
The interlock starts the furnace fan anytime the HRV is turned on.
I messaged Ecobee and they told me to use the B and G terminals. I did, and it worked. Today, I called Vanee and they said to use OL and OC. They said it wouldnt work if I used B and G.
Is there a way to find out what each terminal does? If I could somehow figure out what B+G do versus OL+OC, I'm sure the right answer would present itself.
I used B & G for years before Vanee told me to use OL and OC for a dry contact system.
Vanee are wrong if they say B & G will not work.
There is no difference. With a dedicated HRV the main control uses B & G and the touch timers use OL and OC. They both run the same HRV motors. There is no difference.
Hm. Is there continuity between these terminals? Are they simply the same leads, or do they go through the logic board through some different way?
