Venmar ERV Ecobee Premium wiring

[ghammer80]

Hey,

Just looking for some advice on how to wire my Venmar ERV130 to my Ecobee Premium with as a two wire accessory. I am not sure of what terminals I need to wire to ACC+ and ACC to have Ecobee set the ERV to on. Here are my terminals.. V, Y, W, C, Gf, G, R

Thanks in advance!

Try wiring V to ACC+ and R to ACC- or try the alternate wiring shown in the attachment.

Thanks that worked! but the EVR goes into minimum speed, is there a way to wire it to MAX? The wall control doesn't work now.

That attachment explains the speed configurations and has a NOTE to not use a main control with this setup.

The Ecobee replaces the main control.

Ah yes need to set the ERV to 'DRY' mode and select speed...thanks!

Sadly no dry contact setting on my ERV model. Might look into switchbot and Home Assistant. Thank you.
