A few days ago, the power company knocked on the door and said they'd be cutting off the power for an hour to fix something. I guess because of the moderate temperatures recently, I didn't notice that I apparently haven't had A/C since then.
When I check the thermostat (I think I have the ComfortLink II XL1050), I get an error box saying to contact a dealer, which it doesn't look like I can dismiss from the screen (i.e., I can't access the normal functionality of the thermostat). Specifically, the error is 126.00.
After looking around a little more online, I've been able to gather some more information:
- Per the diagnostic tool, the error description is: "Equipment reporting does not match the equipment originally discovered"
- The Alert History shows a number of errors, but they're all from the day that the power was turned off and they're all the same 126.00 error.
- The "Summary Table" shows that the Primary Zone Expander is offline. The Relay Panel and Communicating Sensor are online. FYI, I'm really not sure what any of this means.
So far, the only things I've done to try to fix the issue are to 1) reset the main circuit breaker for the entire house and 2) reboot the thermostat, neither of which worked.
There's an outdoor heat pump and a main unit in the crawl space. I haven't done anything to either of those. A few specific questions:
- Is it possible that I just need to reset something outside or in the crawl space? I don't see anything like a reset button the heat pump, but maybe there is something there if I remove the panel. I haven't gotten into the crawl space yet.
- Is there something else I can reset on the thermostat to make it all work again, possibly just clearing the previous errors?
This seems like something that almost has to have an easy fix, but I just have no knowledge about HVAC systems. Any suggestions are appreciated.
