I agree with larryllix. The O is probably the reversing valve and it is being set to the heat position.

I have not seen any easy way to find the Link Database size. Other than observing what my assortment of PLMs had inside and what Smarthome sales said when the 2412 went from 477 to 2016. My 2412S Revision 2.75 Firmware 63 was my last 417. Revision 2.9 Firmware 72 was changed to 2016. One thing I do remember is the larger Link Database memory. Was too slow the use the whole 2016. I had seen >800 starting missing things. All the 2413S PLMs are 1023 with a faster memory. Missed the most obvious thing. Pop the top cover and read the part number on the chip. 2412S 24LC32 was the 417. 24LC128 was the ~2000. I did have a old 2412S with the 2414S serial board in it. 24LC256, RTC Chip and its coin cell battery backup. Though RTC and most of the memory was not available. 2413S 24FC64.

At the least. You will have to provide the C Common power connection. To power the 4411TH.

The ISY99i and ISY994i both use the serial port 2412S or 2413S PLMs. The 2414S,2414U and 2814U are all PLC modules and not a PLM. Completely different device and would not work. A 2413U was mentioned as working in the project. The older 2412U may work also. Though depending on it revision. May have the smaller 417 Link Database.

Thank you for the added information. That I had missed reading the thread.

A user has come up with a hardware adapter. Not a simple plug and play setup. Uses a Insteon 2448A7 RF PLM, a Raspberry PI and some adapters. https://forum.universal-devices.com/topic/32546-insteon-2448a7-raspberrypi-isy994/ I have not seen a setup with the 2413U PLM. It maybe done with a Raspberry PI and some adapters. Many Raspberry PI models do have one or more USB ports on them.

Unless the Pollsy can accept a 2414U PLC it will not work. It is not the same as a 2412U/S or 2413U/S PLM. Completely different commands and message speed. 2414U/S PLC 4800,8,N,1. 2412U/S and 2413U/S 19200,8.N,1 It has a Real Time Clock with battery backup. Large memory to store programs we assembled with the Smarthome SALadIDE assembler. That could have the assembled program downloaded into it. Then run alone with no computer equipment connected. If you still had the boxes for the 2413S PLMs you have. It was in the box. Probably in one of the side pieces. Not marked so some didn't even know it was there.

3 AM is the time Query All program normally runs. I also would try and find out what the 51.7F.B8 module is.

That sounds like a good idea. Are you going to have a vacuum solder removing machine. That has a vacuum source and hollow tipped soldering iron. That sucks the solder into a filter and leaves a clean pad around the components lead? As part of the setup? A few of the capacitor legs. Are in plated through holes and I have pulled out the plating when removing the soldered in capacitor. If you get any of the V1.0 modules. It has rework. Where C7, C13 and the coil. Are hanging off of the board and a wire running to the back of the board. IMHO the original design didn't have the PI filter that was found to be needed. You will probably find different value C7 and C13 in different revisions.

You didn't get the switches linked to the one controlling them. With manual set button procedure. The ISY994i would not know of an manual links it did not create. Did you factory rest them at installation? They have been known to ship with test links in them. Though that many switches seem to be odd for factory test links. Do you know the revision of the 2477D? Earlier versions also could have an X10 address in them. If they had an X10 address in them. They could be controlled by an X10 signal.

The kits maybe an easier way to go. As electronic components are also showing shortages now. Looks like it has the improved capacitors for the original C7 and C13, 10uF/50V are the replacements. Smarthome tried different size capacitors in an attempt to get better reliability. You may find 10/35V, 100uF/35V or 100uF/50V. In C7 and C13 positions. Good quality 10uF/50V C7 and C13 would probably be fine. If by chance you have an original V1.0. It is different. The main board only had one capacitor position so their is rework on the board and C7 C13 and the coil are hanging off of the board with a wire going to the back of the board.

A recent look didn't see any of the 2413S PLM on Ebay. I didn't even see any of the older 2412S power line only versions. If someone does see one. Remember they had a power supply issue and some sellers over rate the items working condition.

Thank you for the link. I have most of them. Through web searches and links. Having all of them in one place will be a help to many users.

It will be interesting. To see how long it is until the 2413S PLM is again in stock. Or both the 2413S and 2413U are replaced with the new model in the FCC Database. Universal AC power, larger and faster Link Database , the serial version can supply voltage to run the ISY994i through the serial connector. Like the older 2412S could. Stronger power line transmitter and receiver. Better RF section.

Using an Ethernet type cable. Doing RS232 Serial is not a typical thing we see. You are not alone in thinking it was Ethernet. Unfortunately the 2413S is sold out. So you are not alone in trying to locate one. Some have tried some workarounds with out much success. Like using the 2413U USB. One user has used a Raspberry Pi and some converters to do it but it is not a simple plug and play thing.

The 2413S PLM used with the ISY994i. Is not an Ethernet module. It is a RS232 Serial signal interface. Although the 2413S PLM has a RJ45 style jack on it as does the ISY994i. . A hold over from the earlier Smarthome products. The signals on it are RS232 Serial. The signal pin outs are on the guide in the 2413S PLMs box. Along with a RJ45 to DB9S cable. Not used in the ISY994i setup. The 2413U PLM you have seen. Is a PLM with a USB interface in it. It will not work with an ISY994i. The 2413S has been out of stock for awhile now and electronic part shortages will probably have it out of stock in the near future. The 2413U may still be in stock for now. My thoughts are it was a slower seller and was still in stock.

I have a power strip with built in surge suppressors. It was also designed to filter the AC line. The filter is an across the power line rated .1uF cap in it. That I removed to stop the signal sucking. I also have portable AC. When connected to the line. One of my power line only 2456S3 ApplianceLinc modules is intermittent. A Dual Band module in its pass through outlet on the front seems to have cured it.

The receiving circuits in any Insteon Module. When not transmitting can absorb a small amount of the power line signals. So the one not sending a command. Could absorb a small amount of Insteon signal. If there is a marginal signal path. It could be enough to change things. Especially if it was a system with power line only modules {Like Me ? } As for stacking modules. Only the older designed modules have a pass through outlet. Like the 2450 I/OLinc. Smarthome did warn about stacking them and I can verify stacking the 2456S3 Appliance modules increases their temperature. A 2413S PLM is warm enough as is. I stacked an older revision on top of a 2456S3 for a Dual Band sender receiver only and the back got very warm. I don't mind stacking some modules but never a normally warm module like a 2413S PLM.

If the modules are the power line only type. It is possible the two PLMs in one socket, are absorbing some of each others power line signals. If one or both are the 2412 power line only models. That could also be a factor.

Thank you. My old eyes missed it.

If anyone is interested. The link Mr Bill provided to the wall switch. The specification information shows it has an FCC ID SBP WALL. The internal photos, external photos, tests and a uses manual are all listed and you can download them. As I have done. I did not see a six digit Insteon ID on it but that doesn't mean it doesn't use one.

UDI has posted. If they are not given the proper information. To have an ISY994i properly control them. They will not be supported. Just existing Insteon modules.

This is a long shot. The Insteon 2822-292. Is the 2450 I/OLinc in a Retail Box. Sold by some automation dealers.

Guess it would be too hopeful. That the power line only I/OLinc was going to be replaced by a nice Dual Band one with more features. It does look to me that they are going in a direction not boosting Insteon.

Your thought on the power fluctuations may make more sense. On the off chance the supplies are starting to get weak the power fluctuations effected it more than normally.
