HR92 CYCLEs in vertical position, but stops in horizontal

[Adrian]

Hello,

I have a weird situation with a HR92 that I can't figure out. I've installed it the other day and when I checked on it, it displayed "E2 error valve". There is nothing wrong with the valve because other HR92s work just fine on that valve. I came to the conclusion the problem is with that particular HR92 because if I hold it in hand and close the latch, when it tries to start CYCLE it makes just half of a turn.

After playing around with it for some time, I've noticed that if I hold it in vertical position it CYCLEs for several minutes as it should. But if I rotate it in horizontal position, it stops. See this video: https://drive.google.com/file/d/1MwqRZa ... X0B-v/view

Than I noticed if I put strong pressure on the batteries and the other end, it CYCLEs completely. Please see this video: https://drive.google.com/file/d/1Mu8dKo ... _5E4H/view

Obviously, I need it to work in horizontal position. Anyone knows what the problem is and how to fix it ?

Increase tension on the battery tabs by bending them up slightly from the bottom? Also check the valve base plate as these can break and lock into position causing an E2 error. Failing that, contact evohome support as per my signature.
