I suspect the 3:00 AM Query was disabled. Band aid fix. Was used. Instead of rewriting the program so the reversed sensor option was not used.

If I read the original post. The thermostat is strictly connected to the Sensor and Ground terminals of the I/OLinc. Through its RC/RH and W terminals. Using its mechanical temperature controlled contacts to turn the Sensor Input On and Off. I did not see any reference to 24 volts AC but if there is any external voltage getting into the I/OLinc's Sensor Input. It could be damaged. It has some input protection but probably not able to safely handle 24 volts AC. I also believe the user just disabled the 3:00 AM Query and called it fixed. If the relay output is following the Sensor State it had to be set that way as default in follow sensor input is disabled. Even if not being used. It still had to have been set that way.

The email I got yesterday. Was additional 50% off of bargain bin items.

I am getting regular email offers. Nothing extra special in the last few weeks. Previously in the last few months did have some deals like 20% off with the email coupon code or special prices with a link in the email to the devices special price sales page. Some where not showing on the Smarthome web site. I suspect around the 4th of July they may have a sale. That use to be one of the time of the year when a sale was done.

Sounds like you are now making some progress. From your findings. I would also be thinking power line issues. I have my UPS and computing gear on a Filterlinc. The UPS is on the bottom filtered outlet and the PLM is in the unfiltered pass through outlet on the front.

Your log shows three attempts to access the 2450 with no responses back to the commands to add it. After the start linking finds the 2450's six digit ID and the and process was started. If your log was not running in Level 3. It would show additional information like Hops= for the command sent and may give added information for us. Contacting UDI as suggested may also be a way to go.

I did find the fan and as you said DC motor. I was editing my earlier post when you provided the added information.

I did some web surfing and found the fan you have. That is a unique fan. Sales data says DC motor with many speed choices. Most use an AC fan motor that can be reversed and used AC rated capacitors or multiple winding's to vary the speed.

I don't believe the Administrative Console will show the Serial or USB type for the 2413. Some programs check the Insteon device Category and Subcategory for the device. Both are Category 03 with the Subcategory 11 for serial and 15 for USB. Since the device type is in the main boards firmware. The USB model you chanced to the serial daughter board will report it is a USB type. Taking a serial daughter board from an older PLM like a 2412S would probably fail. As it used a different link database memory chip. That was slower in speed and in some models a different memory size capacity. It also had the fuse installed on it to provide power out of the RJ45 Serial Port Connector.

All the replacement capacitors for the 6.8 uF 250V capacitors are physically larger. So they will stick up more from the PCB. The 6.8uF 250V measures around 10mm diameter and 12mm tall. The KEMET ESX106M400AH4AA 10uF 400V I used was 10mm diameter X 19mm tall. Most of the other ones where in approximately the same size. Do fit OK The UPW2G100MHD1T0 specifications sheet says it is larger physically. 12.5mm diameter 25mm tall. I would also be interested in knowing if it fits.

If it is in the pump mode for output 8. You could use the Smartenit Utility to set output 8 to a zone. If you don't have a spare PLM to use with the utility. Some have temporarily used the PLM in the ISY system to access it. That would most likely mean powering down the system and using the serial cable packed in the PLM box. That many folks unfortunately discard with the box.

Older thread. There is now a Heat Pump version of the Insteon Thermostat. http://www.smarthome.com/insteon-2732-242-thermostat-for-heat-pump.html

I don't think the old 2440 can handle some of the new modules. Not sure if it is a protocol thing. I also can't link one to my Alert Module. That has no issues linking to a TriggerLinc. Too close to my PLM is a known issue seen by many here. In my case other end of house with a 2443 Access Point processing the Insteon RF and passing it by power line to the PLM seems to be OK.

Did you follow the proper procedure when replacing a PLM? Power down the ISY994i and old 2413S PLM. Connect the serial cable from the ISY994i to the new PLM. Power up the PLM and allow it to fully boot up. Power up the ISY994i and allow it to fully boot up. Use the Restore PLM choice it the File Menu so the new PLM ID is written into the Insteon modules in your system.

3 AM is also the normal time [unless you changed it or disabled it] a System wide module query is done. Some have seen the hard to pin down All Module ON occurrence. With the 3 AM Query.

Not sure if the KPL also had tact switch issues. The early SwitchLinc Dimmer and Relay modules. Had the small tact switch the paddles activated not close when pushed. It would click but nothing happened. So one possibility is a bad tact switch. If all the verifying the Link Databases are correct and the wiring is all tight. I have not seen a KPL switch fix. I have seen one for the SwitchLincs

The short availability 2454D SocketLinc Dimmer. Acted the same. Power fail and restore. Always was On at 100% even if it was Off at the time.

You will find many LED bulbs do not smoothly transition on dimmers. Some worse than others.

It is normally hard wired into the four position terminal block inside the 2441ZT Wireless Thermostat. There is a small photo on the probes sales page. Showing where it is normally wired to. Note unless you wire it into the sensor inside the module connection on the circuit board and not the terminal block. The external temperature only shows on its local LCD screen and not sent back for use. You would also have to know its characteristics of the probe. So the one you want to substitute will read correct temperatures.

This is the one they sell for the 2441ZTH wireless model. Not very sure you can integrate it in to whet you want. http://www.smarthome.com/waterproof-temperature-sensor-for-insteon-2441zth-wireless-thermostat.html

It may no longer be available. AT one time First Alert had a dry contact accessory. That would give you a dry closure output from the Trigger Signal. It could be connected to things like an Insteon I/OLinc module or X10 Powerflash module.

Your substitutions should work fine. Both are being used in circuits where a good General Purpose capacitor is fine.

No only on the 2441ZTH display. There is a thread here where the external one was connected to where the main sensor is. Then it was what was reported not the internal one. http://forum.universal-devices.com/topic/9152-how-to-monitor-water-temp-via-isy-and-catch-more-fish/?hl=2441zth

Not 100% sure if the 2477D has the blink on traffic feature or on power line noise also. If it does the 2672-222 maybe sending noise back on the power lines and the 2477D is blinking its LEDs from the noise or bogus Insteon messages. Is the 2672-222 always in a live socket and you turn it On; Off and Brightness level with Insteon Commands? So that if is going bad. It has power all the time. Flashing at 60 or 120 cycles could be the power supply in the 2672-222 is starting to fail.

Not sure if you would get anything additional from the FCC Internal Photos of the Fanlinc. They are on the FCC Database. Grantee Code: SBP Product Code: 2475F In the detail choice. https://apps.fcc.gov/oetcf/eas/reports/GenericSearch.cfm Yes you can find most of the Insteon Dual Band modules in the Database. All have the same Grantee Code and different Product Codes.
