Programs Running Unreliably

[Guest Dr. Emilio Lizardo]

I am having problems with programs running reliably. I have an ISY/99 pro with a dual band PLM. I have a pair of 2443 Access Points on opposite legs of the power. I also have a power line coupler in the circuit breaker box. The ISY is in an electronics room with all my A/V equipment. The A/V equipment is on two power strips. Each power strip has a filterlinc noise filter on it. I have run an extension cord from an outlet that is on a different circuit than the one that powers the A/V equipment to power the PLM. I can execute the “then statement†of most programs manually and they will work but not all the time. I have a program that turns down the thermostat at about 10pm in the Master Bedroom and one that turns it up at 9am. The 10pm program seldom executes but the 9am one executes reliably. I have programs that turn fans off after 30 minutes of run time. These seldom execute any more (they did at one time). I have programs that turn some lights on 30 mins. after sunset and off at 10pm. These execute near flawlessly. Scenes execute near flawlessly. Any suggestions as to where I might have to look to find the problems. All programs are tied to a change in Status vice Control.

 

I have 2 circuit breaker boxes (we’ll call them Left and Right). The phase coupler is in Left. Right is closer to the meter. Should the phase coupler be located in Right?

 

Thanks for any and all help that you can provide me.

Some things to look at. Run the 4 tap Set button test on the Access Points to verify that they are both in RF range and on opposite 120v legs. Being on opposite legs but out of reliable RF range is the equivalent to not being there at all.

 

The passive phase coupler should be in the power panel nearest the meter so that it is closest to the central part of the electrical system.

 

The PLM and Access Point (used for coupling) plug points should be central to the electrical system. If they are not powered from panel feed by the meter change the plug points.

 

The thermostat problems could be RF issues. Not in reliable range of the Access Points or Dual Band PLM. Could be another symptom of the general powerline communication problem. Baby monitors, cordless phones can interfere with RF communication.

 

The FilterLincs on the AV equipment are good. If there is a UPS/PC on the PLM circuit they should be on a FilterLinc.

 

Look for devices/appliances that are On when communication is at its worst. CFLs, LEDs, fluorescent lights, LCD TVs, cell phone chargers, are all potential sources of signal interference.
