Hi there

Was wondering if anyone has had the error code “er 01” on their HRV display?
Initially I thought it might be the filters but the display is saying I’m still at 77 percent.

It’s the Arizona 5 model installed in 2010.

Any ideas?

Have you tried switching it off (likely you will need to find the correct circuit breaker on your fuse box).


Leave it off for a minute and flick it back on and see if that worked?

Yes turned power of a couple of times hoping that would reset it - but still no luck...




I know it hasn't had new filters in the past 8 years (even though the unit says they are still at 77%) - So I might put new ones in hoping that would fix the issue...?

It'll likely be filters...ours have been replaced every couple of years and they are often full of dust.
