I just got off the phone with Smarthome. The rep didn’t seem to think a three phase service is the problem. They are replacing the device assuming that the first one is defective. I am not optimistic of the outcome because I agree with your theory on what is happening here. He did state the sense the controller is dual band and communicates via RF there should not be this kind of interference with the other devices. We will see….

The service to the building is 3-Phase; the controller itself is hooked up to a standard 220V 20Amp circuit. In order to get all my INSTEON devices to work properly with my 3-Phase building, I had to use three access points connected on all three phases in the building. Sense the 2477SA1 is also an active phase repeater my thought was it was interfering with my other devices. I plan on calling tech support later today but the relay is connected correctly.

Thanks for the advice. I will disconnect the load wires cap them and trigger the controller to see if it is noise. What I do know is, when the controller is in the on or off position supplying a load or not I am losing my INSTEON signals. I am using this device at my business to control a 220V 20Amp blower motor. The building is 3-phase and the controller has an active phase repeater built in for INSTEON signals. The phase repeater is only switching between two of the three phases. Throwing the breaker fixes the problem. My thought is the repeater doesn’t work when the breaker is off….. Maybe this controller is not compatible with 3-phase buildings? To me, it looks like this relay controller is a crapshoot at best. I have been reading a lot of things about it some good and some bad. It seems that there have been more than enough problems going around with it to steer clear. I hooked up an Elk Heavy Duty Relay #72800 to control my 220V 50Amp compressor and it works flawlessly! Well, that was until I hooked up the 2477SA1. The Elk is around 80 bucks and is controlled with any type of 110V OutletLinc, ApplianceLinc or In-lineLinc. Maybe this is an option for those of you struggling with the 2477SA1. If I can’t fix this soon I am going to get another Elk and move on with peace of mind that my system is trouble free.

This is kind of in the same subject matter and was wondering if anyone could give me some input to my problem. I just installed a 2477SA1 load controller and I can link up to it and control it on and off in my admin console but, all my other devices started losing communication and I would get the red exclamation point next to them. I cut the power to the 2477SA1 at the breaker panel and would query my devices in the admin console and was able to get them back on line. Turn the breaker back on and get the same issue, able to control the 2477SA1 and lose my other devices. Any input would be appreciated. Thanks.
