Owners Specifications and Submittals Commissioning - Attention to detail is a prerequisite for commissioning. This is especially true when looking through the project specs and finding the owners requirements for the project and then matching the owner requirement specs to what is provided by the contractor and then documenting everything as the commissioning specifications require. This requires reading the specifications and matching everything up with the submittals for the project. Sometimes this is a monstrous task especially for larger projects with various types of infrastructure. (more…)

Direct Digital Controls Commissioning | Building Automation Systems - Preface –This article is not all inclusive of everything required to properly commission a control system. I wrote this because of my observations of a colleague and their frustration on a seemingly never-ending project for which the colleague called me in as a consultant to complete the project for the controls. My colleague’s background was lacking in experience for controls whereas my background does not suffer from this lack of experience in both controls engineering and commissioning control systems. Anyhow, buckle your seat belts, this is a long piece where I cover a lot of ground although I feel it is not complete. It is simply too long to add to and I will likely write an accompanying article in the future when I have time from my busy schedule. Comments are always appreciated in the comments section below.
Direct Digital Controls Commissioning | Building Automation Systems - On many commercial construction projects the HVAC, lighting, electrical, and other systems including life and health are controlled by direct digital controls (DDC). Otherwise referred to as building automation systems (BAS), building monitoring systems (BMS), or energy management systems (EMS). These systems can be complex without proper understanding. It is important before the building is turned over to the owner, that these systems are commissioned properly. Or otherwise set up and tested to ensure they operate properly. This includes ensuring the operators are trained in its use and are given proper access levels to monitor equipment and systems DDC controls in the building. (more…)
ArcoAire Gas Furnace Reviews | Consumer Opinions- ArcoAire has two specific model series for their gas furnaces. The DuraComfort™ Series and the Performance Series.

How to Wire a Run Capacitor to a Motor | Blowers & Condensers – Sometimes when a blower or condenser fan motor goes bad a technician or even a DIYer has issues wiring the new motor and capacitor. Most motors come with clear instructions or a wiring diagram on the side, however, some people still struggle with the wiring part of the motor to the capacitor. It is important to get it right to prevent problems including burning up the new motor or even causing a dead short in the wiring and melting the wire. A PSC motor will run without a capacitor however it will run at higher temperatures pulling more amperage than design. Here we will illustrate the proper wiring for a motor to a run capacitor.

Blowing Low Voltage Fuse Breaker Trip | Control Wiring Troubleshooting - I’ve got a 5 amp fuse that keeps popping on a circuit board. The voltage out of the transformer reads 26.3 volts. I am still popping fuses and reading over 24 volts. Can you help?
I can give you some of the basics to help you but first, we need to clear a few things up. You seem to think the voltage is what is causing the fuse to blow. It is not voltage that causes fuses or breakers to blow or trip. It is amperage. It is likely you have a dead short from what you are describing but let’s go through the basics first: (more…)
Water Heater Anode Rod - Modern water heater tanks are constructed of steel with a thin glass lining to protect the steel from corrosion. The glass lining will eventually crack, but there is another level of protection from corrosion inside of the tank: the anode rod.
What is a Water Heater Anode Rod?
An anode rod is a long metal (usually magnesium or aluminum) rod that attracts the corrosive elements from water in order to protect the steel tank. Anodes are often screwed into the top of the tank and go almost all the way to the bottom. It is sometimes called the sacrificial anode rod because of the way it sacrifices itself in the tank to protect the steel.
Because the molecules of magnesium and aluminum give up their electrons quicker than steel, rust will only occur on the anode rod while it still has metal to sacrifice. By diverting the rust to only occur on the anode rod, it can extend the life of your water heater. The anode rod’s lifespan depends on a few different factors, namely: quality of the water, the water temperature, amount of use the tank gets, and the overall quality and construction of the tank. If there is salt added to the water as in the case of softened water, anodes corrode at a faster pace.
Water Heater Anode Rod Options
Adding an additional anode rod should be considered if your model allows for it. By taking up more surface for it to absorb corrosion you can increase the life of your water heater even longer. However, it may not be a good idea if you are having odor problems as it can make the problem worse.
If you are thinking about adding an additional anode rode to your tank, make certain that both are made of the same metal. If one is magnesium and the other aluminum, the magnesium will be consumed more rapidly and you won’t get the desired outcome.
Another option is a powered anode rod or impressed-current anode. These do not sacrifice themselves in order to protect the tank, they instead are plugged into an outlet and stops the tank corrosion by releasing continuous but small amount of electric current in the water, which prevents the electrochemical reaction that usually causes metallic corrosion. The benefits of a powered anode rod are that they last much longer than a regular anode rod, they usually can take care of smelly water and are better for the tank if you have soft water in your home.
Water Heater Anode Rod Types
There are two anode rod configurations, hex-head and combo or outlet anodes. Hex-head anode are often found on their own port on the top of the tank. Depending on the model, the hex-head might be exposed or under a plastic cap halfway from the center from the edge. Combo rods have a steel nipple that is plastic lined and used in the hot water port. Frequently tanks with a longer-term warranty have one combo and one hex head, although some just have one combo rod with no option for a second rod.
Water Heater Anode Rod | Conclusion
Most tank water heaters last approximately 10-12 years, and they are not cheap to replace. Anode rods last 3-5 years and are about 20-50 dollars. Powered anode rods are about 250 dollars. By periodically checking your anode rod and replacing it when necessary, you can prolong the life of your water heater significantly.
