Nobody likes technical faults, especially when it’s a matter of comfort and convenience but unfortunately, it is something that can’t always be avoided. Today, homes and businesses rely on a rising amount of technology to support day-to-day activities, increasing the chance of technical issues. Luckily, many of these can be fixed by simply restarting the product without disrupting our experience or enjoyment for too long.
Turning our attention to air conditioning, these are also built so that basic maintenance can be conducted by the operator:
- Changing a filter to improve airflow
- Inspecting ducts and general cleaning
- Removing causes of clogging from around outdoor units
While these quick-fix solutions are to let the end-user improve comfort by themselves but there are issues that only a professional can identify and solve.
The use of climate control goes beyond our comfort and it is used by a multitude of services and trades where malfunctions implicate health risks or damage to business: healthcare facilities, laboratories, pharmacies, food processing and storage companies, enclosed commercial spaces… the list goes on. In order to facilitate the speed at which issues are identified and resolved, error codes are key.
But what are air conditioner error codes? Below, we explore the fundamentals of what they are and why we use them.
What are Error Codes?
Error codes indicate that a device, piece of equipment or machine has a problem within its system that needs attention. Generally, the more intricate the system is, the more particular the error codes are. In this case, we are referring to the error codes that Hitachi air conditioners produce when a technical fault is recognized by the equipment.
Air Conditioner error codes are a means of letting the technician know what the issue is with the equipment and explaining what the ‘symptoms’ are. If a technician had to diagnose the problem without any indication as to what could be causing it or to which part it is related, it would make the task difficult and time-consuming. So, not only does it make it easier for the technician to fix, but it also means that the client is able to continue using their air conditioner as swiftly and as safely as possible.
Once triggered by a fault in the system, error codes are easy to find on all of our products: Indoor units display them on their control screen and outdoor units display their error codes on the panel which is located behind a detachable door.
What’s more, is that our error code ‘language’ is used on all Hitachi HVAC products within each range, and the majority of these codes are the same across different regions around the world.
Now, we want to make this ‘language’ as useful and as enjoyable possible, which is why we enlisted The Solvers to help you, the technician, maintain your professionalism and enjoy what you’re doing when on a job.
Introducing The Solvers Video Tutorials
Each episode of The Solvers focuses on one Hitachi Cooling & Heating air conditioner alarm code at a time, explaining what the code means, its possible causes, the tools needed to solve it, and the possible solutions available.
The essence of this series is to offer easy-to-follow air conditioner tutorials that help train professionals and encourage them to become even better at what they do. We also want to provide them with a new tool that makes their job easier, by minimizing the need to carry extra instruction manuals when on the job.
As mentioned previously, has been made exclusively for HVAC professionals, specifically for Installers, technical service, and maintenance teams that can be accessed and views 24 hours a day.
To walk you through the process, a team of specialists are on hand to show that it’s easy to be professional and enjoy your work. Get to know John Trust, Amy Smart and Maz Snappy in our first episode.
For the first release of The Solvers, there are a total of seven videos, six of which are tutorials dedicated to individual error codes, including what to do in the case of an 08 alarm code (when the temperature of the compressors discharge is too high) and also how to solve a 31 alarm code (when the outdoor unit capacity is incompatible with the indoor unit capacity).
Season 2 of The Solvers Video Tutorials
In the new season, as well as talking about error codes and the commercial segment, The Solvers also talk us through what certain error codes mean on residential air conditioners and heat pumps.
For example, we get a chance to review all the steps that must be followed when installing a Hitachi residential air conditioner, including the tools required and the safety regulations that must be observed before starting. Sometimes at the end of an installation the equipment can fail, which is why it is important to be aware of the different components with which Hitachi Residential Air Conditioners indicate potential risks of failure.
The Solvers show us how to check an Error code 202 on Hitachi’s aerothermal equipment called Yutaki, which means that the wired thermostat was incorrectly adjusted during commissioning.
We then look at the different steps for the preparation of VRF equipment before the commissioning, which is essential for this kind of installation.
Just like with the first season, each new episode of The Solvers helps HVAC professionals address tasks they might face when working and push their knowledge to the next level, showing the tools needed for day-to-day work, and sharing more solutions and practical tips.
