I reached out to my contact at Hopkins and it sounds like everything is functioning correctly except for the E1 code when you hit the manual override. That tells us that there is a problem somewhere on that blue controller output wire. There is a short somewhere to ground. This could be a nick in the wire insulation or it could be corrosion at the connector.

I recommend cleaning all your contact points and tracing your wire if that doesn't solve your error code to check for issue. You can replace that wire if needed completely with # 10-1-1 sold by the foot.
