Behemoth60 Posted February 12, 2019 Share Posted February 12, 2019 I am Running an old 1.7.0 system that was installed in 2008. It controls my hydronic radiant in-floor heating system using 4 Contact Relay extenders, and household lights. I've been bragging about my system's flawless service for all these years, but after 11 years of faithful service, I had my first failure last night.... the power supply in the HC300 burned out. Of Course, it happened in Feburary, in Canada, during the coldest spell of weather so far this winter. It got to -27.2 C at my place last night! (For you americans, that's the temperature of your freezer multiplied by my outrage that you don't use the metric system) While I am waiting for a replacement HC300 to arrive ($55 on ebay), I've had to hotwire the controller to an unused 5V supply on my home PC. Fortunately, it works! The controller came back to life with all its memory and programming and heat has returned to my home. I sure hope I haven't ruined my warranty.

Pounce Posted February 12, 2019 Share Posted February 12, 2019 I'm assuming you are just going to swap the power supplies when you get the replacement. Otherwise: http://www.5khz.com/2014/05/19/replacing-the-power-supply-in-the-control4-home-controller-hc-300/ Quote Link to comment Share on other sites More sharing options...
NextGenAV Posted February 12, 2019 Share Posted February 12, 2019 Couldn't you just buy a 5V PSU rather than a new (old) HC-300? If you bought an enclosed one like a laptop PSU ... something like a 20W one would do. I did something similar to an HC-300 years ago and it still plods along quite happily. The 300s are great for those low speed automation tasks Quote Link to comment Share on other sites More sharing options...

shoaib.chaudhry Posted November 21, 2019 Share Posted November 21, 2019 The Power supply doesnt exist anymore from mouser or allied electronics. I searched and searched and finally came up with a brilliant idea. I didn't want to spend a thousand bucks, so decided to try a 15 bucks solution, and it worked. I removed the defective power supply and threw it away, then got this part from amazon: https://www.amazon.com/gp/aw/d/B000MGG6SC?psc=1&ref=ppx_pop_mob_b_asin_title Connected the MULEs connector( 4 pin on control board), unit powered on. Disconnected the power slot in back and used it to route the brick wire out of HC300, and plugged everything back in. All is working fine as my HC300 is merely being used as an IO extender. Put the cover back on and put all screws back. Last year when my HC300 power died, I bought one unit from ebay and swapped power, but it lasted only a year. This will hopefully last next several years. Good luck if u do decide to do the same. Quote Link to comment Share on other sites More sharing options...

Several HC300s, HC200s, Media Controllers, HTC's, mini touch screens and even the old school sytem remote controls. The way i look at it if you're invested in the eco-system just upgrade to the latest and greatest (kind of like upgrading cars). Quote Link to comment Share on other sites More sharing options...
shoaib.chaudhry Posted November 24, 2019 Share Posted November 24, 2019 I definitely would...if money grew on trees. I know your CTO has bills to pay, but so do I why would I spend 1000 bucks when I can get by just fine spending 15 bucks. Quote Link to comment Share on other sites More sharing options...

Andrew luecke Posted October 20, 2022 Share Posted October 20, 2022 At this point of time, the HC300's are 5 generations behind, 15 years old, and the cost of the power supply costs more than even a HC800 which was released 5 years later and was the high end model at the time (despite their model number, the HC300 is MUCH older than the HC250). In my opinion, nobody should still be using them. In fact, none of the drivers we write anymore (regardless of how basic) will support anything less than 2.9.1 (and I recall the last OS for the HC300 was 2.5.3). And most lighting drivers we write, require OS3.3.0 or later Quote Link to comment Share on other sites More sharing options...
