Er13 - Master CPU informs companion CPU that triac is going to turn on but companion never sees it turn on.
First try to recycle power to see if error code clears (unplug power to unit, wait 10 seconds and plug back in).
After trying to recycle power Error Code 13 returns then normally the control box would need to be replaced BUT there is one more thing to check. If you are using an Electric Strike and are not using the supplied Diode that comes with the Sr Swing, the noise from the strike has the potential to trigger this error code 13 on the CB.
So if you have an ES, double check that you are using the supplied Diode and if not, putting one in should eliminate this issue.
Here is the information on the Diode and how to wire up……. This ES filter kit (diode and instruction sheet) is set inside the Sr Swing header assembly, not packed with the CB.
There are two diodes (one extra). They are a 1N4148 diode. See here for picture of the ES filter kit.
For older Sr Swing CB (shipped prior to Dec. 9th 2019 - 710164-00). See here for wiring instructions.For newer Sr Swing CB (shipped after Dec. 9th 2019 - 72940) See here for wiring instructions.
For identification, see here for photo of old and new CB.
