Sometimes Simple is better.....
The best new product from Siemens...
that is a very difficult question to answer given all the new products and solutions Siemens is bringing into the HVAC and Smart Building Controls Space.
The Siemens new line of Variable Frequency Drives, their integration of Comfy and J2 Innovations into their suite of building automation controls, and Desigo are just a few that come to mind..You can click here and find out more from our interview with Siemens senior sales manager, Josh Felperin.
As cool and innovative as all those products are, I want to feature a product that might not be recognized for just how special it is ….
The Siemens POL 220 is a carefully thought out, elegant new version of the economizer control. Siemens has reimagined, and redesigned the classic economizer controller.
Some of the things I really like about the Siemens POL:
- You don’t need any software to configure it. I am still old school at heart , so dip switches and potentiometers work for me. They make me feel young again! And the fact that Siemens made sure not to skimp on the pots and dip swiches, makes them feel good in the hand and easy to see.
- I can select three free cooling strategies: temperature, humidity , and even Demand Control ventilation based on CO2 sensors.
- The plug and Play Feature will automatically determine which configuration you need once you have your sensors wired and power up the controller for the first time.
Get the 411 on Indoor Air Quality
Is your building sick?
Are you liable if someone becomes ill from contaminants in a building you are servicing?
What are the most harmful pollutants and how can you get rid of them?
These and many other IAQ questions will be answered in this five part Indoor Air Quality Training course taught by HVAC ControlPro Tim Chamblee and held at HVAC and Smart Building Controls Distributor Stromquist & Company.
Indoor Air Pollution and Health
I pulled this off the the EPA website:
Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns.
Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later.
Some health effects may show up shortly after a single exposure or repeated exposures to a pollutant. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Such immediate effects are usually short-term and treatable. Sometimes the treatment is simply eliminating the person’s exposure to the source of the pollution, if it can be identified. Soon after exposure to some indoor air pollutants, symptoms of some diseases such as asthma may show up, be aggravated or worsened.
The likelihood of immediate reactions to indoor air pollutants depends on several factors including age and preexisting medical conditions. In some cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person. Some people can become sensitized to biological or chemical pollutants after repeated or high level exposures.
Certain immediate effects are similar to those from colds or other viral diseases, so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution. For this reason, it is important to pay attention to the time and place symptoms occur. If the symptoms fade or go away when a person is away from the area, for example, an effort should be made to identify indoor air sources that may be possible causes. Some effects may be made worse by an inadequate supply of outdoor air coming indoors or from the heating, cooling or humidity conditions prevalent indoors.
Other health effects may show up either years after exposure has occurred or only after long or repeated periods of exposure. These effects, which include some respiratory diseases, heart disease and cancer, can be severely debilitating or fatal. It is prudent to try to improve the indoor air quality in your home even if symptoms are not noticeable.
While pollutants commonly found in indoor air can cause many harmful effects, there is considerable uncertainty about what concentrations or periods of exposure are necessary to produce specific health problems. People also react very differently to exposure to indoor air pollutants. Further research is needed to better understand which health effects occur after exposure to the average pollutant concentrations found in homes and which occurs from the higher concentrations that occur for short periods of time.

If you are in the HVAC and Mechnical Business you know closing out a Build Out project can sometimes get very confrontational. If something doe not got right on the job there can be lot’s of finger pointing, and these situations can get expensive.
So how can the HVAC Pro avoid these situations?
Meet Brent Burrows from Entek in Atlanta. Brent gives us a simple, effective three step process that will have your HVAC Build Outs go very smoothly.
If you are an HVAC Pro who has a Tech Tip to share, but you don’r want to spend time editing videos, I have an offer for you. How about you record your tip, send it to me, I will do the edits and post it on my YouTube Channel and give you full credit and any of your contact information you would like to share.
Many of our guests and contributors have gotten jobs, just because they were seen on one of our videos. Just last month a Systems Integrator got a huge job doing the controls on five buildings, so sharing your knowledge can be very profitable.
So if you are interested please type” YES” in comments.
PID tuning constants can be one of the most confusing concepts in HVAC and Industrial Controls
but it doesn’t have to be.
II have had a lot of requests to create a video explaining PID control and how to tune a control loop.
PID stands for Proportional, Integral, Derivative. These are calculus concepts that have to do with the rate at which variables change in relation to each other.
Tuning a PID loop can be very complicated and is much an art as it is a science.
For the HVAC control pro, and for most HVAC control loop tuning applications the process is usually pretty simple and straight forward, especially if you understand the theory.
Hopefully, this video is helpful! Please let me know in comments if it helped, and what other HVAC controls videos you would like us to create for you.

The new BAScontrol22C
which supports BACnet client capability in addition to the existing server functionality, is now available. Most BACnet devices are servers, which do not initiate requests to other BACnet devices other than an initial “I-Am” broadcast when first joining the network. The BAScontrol22C is a BACnet client, which means it can initiate requests and expect BACnet servers to respond to requests as data is exchanged.
“The BAScontrol22C gives users the ability to access point values and/or control other BACnet devices in the network,” said said Zach Nestov, Product Specialist. “The points obtained over the BACnet network can be used in the BAScontrol22C’s Sedona wire sheet application logic, become scaled, calculated, and/or converted to different data types, written to other BACnet devices, served up to BACnet supervisory controllers and operator workstations by using Virtual Components, as well as be monitored, displayed, or exposed for configuration on BAScontrol22C’s web page by the use of Web Components.”
Reading points over BACnet networks can be very useful in several applications such as reading an outside air temperature from a BACnet networked sensor device, reading zone temperature, humidity, CO2 PPM, and other comfort parameters from a BACnet networked wall setter/thermostat device, or exchanging control values/points with another BACnet controller or supervisory controller/ workstation. In remote access applications, by employing Remote Access VPN IP routers (such as EIPR-V, EIGR-V), the BAScontrol22C can obtain BACnet points from devices on a remote BACnet network.
The BAScontrol22C supports BACnet/IP Client and Server functionality using a 2-port Ethernet switch connection. The controller complies with the B-ASC device profile having a convenient mix of 8 universal inputs, 4 binary inputs, 4 analog outputs, and 6 relay outputs. In addition to 22 physical points, the BAScontrol22 has 24 Virtual Points for use in wire sheet and data exchange with BACnet supervisors.
The BAScontrol22C uses its direct Ethernet ports to communicate to BACnet/IP devices on the network. With the help of a BASrouter – BACnet/IP to BACnet MS/TP router – the BAScontrol22C can communicate and interface with BACnet MS/TP devices as well.

Panel Builders pay Attention to the CTRLink Switches Designed for Automation
If you are designing a building automation enclosure that includes Ethernet or BACnet/IP communication, chances are you are looking for an unmanaged Ethernet switch to tie things together. Budgets are always tight, and there is a temptation to utilize inexpensive household grade switches from manufacturers such as Linksys or D-Link. However, we feel you are being penny-wise and pound-foolish.
Contemporary Controls has more than 40 years of experience designing products for unattended operation in environments not conducive to office grade equipment. Our CTRLink “Skorpion” Series of plug-and-play Ethernet switches have the features you need for reliable performance:
- 24VAC (or DC) Powered – No need to find a place to plug in a wall-wart power cube (or install a receptacle). Our switches can operate from the same 24 VAC power source as all your other components. Secure positive locking screw terminal strip connections – no banana-plug here. Our hard-wired power connector is vibration proof and tug proof.
- DIN-rail or panel mount – No trying to balance a desktop switch somewhere in an enclosure while building custom shelves, using Velcro, resorting to duct tape or just hanging from Cat 5 cable.
- 10/100/1000 Mbps Speed – No configuration necessary. Our ports automatically configure their data rate, duplex, and utilize the Auto-MDIX protocol so straight-through or crossover cables can be used.
- Activity/Link and Data Rate LEDS – Each port visually conveys key information to tell you what’s happening on your network.
- 5, 8, and 16 Port Models – We have the size you need, all with a similar form factor. Some models even offer fiber optic ports for those long-haul connections.
- Compact Size – Widths as narrow as one inch and a vertical form factor means we blend seamlessly with other nearby control equipment. Available panel mount for shallow depth (less than one inch).
- Rugged Metal Enclosures – We use metal enclosures for strength and EMC protection. All Skorpion switches are EMC immunity tested.
- Wide Temperature Range – Our switches are 0° to 60°C rated. Office grade products are not.
- UL 508 Listed – Many jurisdictions require control cabinets to be UL 508 compliant. Using unlisted components within your enclosure can create issues and added expense far beyond the few dollars you saved up-front.
In addition to unmanaged switches, the Skorpion family also offers Managed Switches and Diagnostic Switches. These come in the same form factor and with the same features outlined above. Should your needs change, upgrading to a more complex switch is a simple as unclipping one and clipping in another.
