Poor Design

Glenn, that was good work.  It seems that the dehumidfier was not tested properly after it was desiged.  Kind of reminds me of 1960s English sports cars.

naperlou;  I was puzzled that the two heaters were not balanced, but I wouldn't have found that out if the overheat hadn't tripped.  I contacted the manufacturer several times (e-mail) during the process.  I don't know if it caused them to review their design.

You can only hope the feedback to the manufacturer prompted their engineers to make changes, Glann. Not necessarily, though. Let's hope that the move toward social media in design will help the feedback loop reach the design function.

GlennA, normally we are deploying multiple sensors at different places and average of the sensor values are accounted for decision making. Even most of such devices are equipped with more than one sensor for better accuracy. In such cases these types of failover can be minimized.

The design constraints were composed by someone with no experience building such a room.  I was told the PLC would only have to monitor the room temperature and relative humidity - the air conditioners would use their internal sensors for temperature, and dehumidifying was assumed to be included.

I remember a saying I was told years ago:  Do you know the best thing about beating your head against a brick wall ?  It feels so good when you stop.  I stopped worrying about the parts of the project that I had no input on or control over.

With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
US factory orders for durable goods tumbled 3.4% in December on a big drop in new bookings for commercial aircraft, according to data the Commerce Department released Tuesday.
