Unable to Link 2477SA1 Load Controller (Dual Band) to ISY99

[Guest martink]

Bought a couple of Load Controllers last year to run my 240V Patio heaters. Just now got an electician to install and can't link to my ISY99 or to any other devices. I have linked an ApplicanceLinc 2456S3 located right next to the Load Controllers and a 6 button 2486D KeypadLinc dimmer with the ISY today with no problem - worked first time. Therefore I don't think I have a communication problem within the system - just with the two Controllers.

When I tried to link to a Keypad button, I would seem to get a reaction sometimes, the Controller and Keypad stops blinking before the time out, but they don't seem to get linked. When I try to link to the ISY, I get the following message:

[-200000] Failed writing the highwatermark [N/A]

[-200000] Node not added - failed removing links [ (device address I entered)]

I have tried all three option re removing links, adding devices etc for adding a device on the ISY.

My ISY generally works OK otherwise and I only have about 20 or so devices on it.

Any ideas?

Hello martink,

 

What happens if you bring the load controller right next to the PLM. Do you still have issues linking it?

 

I suspect the signal is not getting to your load controller or perhaps the load on the controller is causing noise.

 

With kind regards,

Michel

Thanks Michel

 

I will try moving the PLM and ISY close to the Load controllers when I have more time to spend on this ( it will be a bit of a task to do this)

 

However, I am able to program and operate an ApplianceLinc located right next to the Load Controllers in a receptical in the same panel as they are with no problems so I don't think this will make a difference.

 

The 240V Smarthome Load Controllers are very simple to wire - 2 line in's, 2 Load wires - so I can't imaging the electician wired something wrong. The controllers do control the load when I use the manual button on them.

 

Therefore, I am thinking there must be something wrong/defective with the two new controllers I got. Does this make sense? Is it worth trying to move the PLM given these facts?

[Guest martink]

OH - in addition, I do get the following message when the ISY is trying to find the controllers:

 

"[ (address)] Failed getting engine version. Reverting to i1"

 

I think I also get this message when successfully programing a new item like the ApplianceLinc so I was thinking this is irrelevant but thought I would add this fact.

 

Thanks for your help on this!

Sorry for the multiple posts but I forgot to say that the Load Controllers are controlling a purely resistive load - Patio Heaters so I don't know if they would produce interference. Certainly they are not provided any power in the programming process so I don't think that they could be interferring.

Hi martink,

 

How are you trying to link the load controllers? Using Start Linking method or by address?

 

What is your ISY's firmware version?

 

With kind regards,

Michel

[Guest martink]

My ISY firmware is 2.7.15

 

When I got your question, I tried the "Start Linking method". I previously only tried by address and linking to a KeypadLinc.

 

I managed to get one of the controllers to be listed on the ISY but I am unable to control it. The screen shows the on/off buttons but no status. I went to another existing device that I can control and the status was blank too but I could still control it.

 

Got somewhere further but not far. I am thinking I should be updating the firmware but have been avoiding it until I am sure I need to. Last time I updated, I lost all of my links and scenes and had to start over.

Support for the Load Controller device type was added at 2.8.1. If you upgrade go to 2.8.16 which is the latest Official release. The lower 2.8.x images are Beta level. Same with the 3.1.x images which are also Beta level.

[Guest martink]

Back at it after being away for a while. I updated to the latest ISY software release and am now able to control the one Load Controller that I managed to link to the ISY previously. However, I am still not able to link the other Load Controller which is wired into the same panel and located right next to the one that I was able to link to. If I try to link by address, I still get the "reverting to i.1"message and the error messages I noted previously. I have now moved my ISY and PLM right next to the Load Controllers and plugged into the same panel. Before and after I moved the PLM, I noticed that when I use the "Start Linking" method, my PLM (2413S V1.0) starts buzzing and ticking when I put the Load Controller in linking mode but will still not link. The PLM will continue to buzz even after the Load Controller moves out of linking mode until I send another command from the ISY or unplug it. The PLM otherwise works fine with the other Load Controller and all the other things on my system.

 

I am beginning to think that there is a problem with the one Load Controller, the PLM or both. Any more ideas/suggestions?

[LeeG]

Two things to try; factory reset the 2477sa1, reverse the red and black wires connecting the circuit breaker to the 2477sa1.

[Guest martink]

Tried both factory reset and reversing the wires on the circuit breaker. Unfortunately, no difference. PLM still buzzes and no linking the 2477SA1 Controller.

 

Anything next?

[LeeG]

Nothing I can think of. Time for a new one.

[Guest martink]

Thanks LeeG and Michel for your help. I will get a replacement and try that.

Got my new Load Controller and it linked right away. This was all about a defective controller. Thanks for everyone's help!
