“We believe the winning energy management system will be the one that does the best job of seamlessly adapting to people’s lives and preferences without requiring them to constantly make adjustments to their thermostats,” said John Steinberg, executive vice president and co-founder at EcoFactor. ”Soon geolocation data from mobile devices will help increase both savings and user comfort while letting consumers get on with their lives.” Source: EcoFactor
4. US Patent 3644864A COMPOSITE THERMISTOR TEMPERATURE SENSOR HAVING STEP-FUNCTION RESPONSE: Abstract: A temperature sensor including first and second PTC thermistor elements each having a well-defined transition temperature above which the resistance of the element rises relatively abruptly and below which it changes relatively little, the transition temperature of the second element being substantially greater than that of the first element. The thermistor elements are adapted to be substantially identically thermally responsive to a body whose temperature is sensed by the sensor. The elements are connected in series-circuit relationship to cause the sensor resistance to be a series-equivalent resistance which varies as a function of the resistance of the elements and changes relatively abruptly at temperatures determined by the transition temperatures of the elements thereby providing the sensor with a step-function R vs. T characteristic.

New BAScloudVPN Service from Contemporary Controls — Secure Communications: Downers Grove, Illinois, Contemporary Controls’ new BAScloudVPN service makes it possible to provide secure, remote communication over the Internet by by hosting a Virtual Private Network (VPN) server in the cloud. Internet can be a challenge since firewalls block messages that originate from the Internet. Although it is possible to open up ports in the firewall using Port Forwarding, IT professionals are reluctant to compromise the security of their network and usually decline this type of request. Without permission from the IT department, the systems integrator is left with few options. However, one solution to this problem is to incorporate a VPN.
Contemporary Controls EIPR-V Skorpion VPN Router provides secure remote Virtual Private Network (VPN)
Downers Grove, Illinois (September 2013) – Contemporary Controls EIPR-V Skorpion VPN Router provides secure remote Virtual Private Network (VPN) access to the Internet via a cellular or Ethernet connection. Using the EIPR-V VPN Router in conjunction with our BAScloud VPN service provides an opportunity to enjoy the benefits of a VPN without maintaining a resident VPN.
Honeywell Introduces New Flanged Control Ball Valves: The new VBF5011/5013 Flanged Control Ball Valves can replace legacy V5011A/V5011B and V5013B/V5013C globe valves with enhanced delivery and performance. These valves can be used in hot and chilled water applications with glycol solutions up to 50% in closed loop heating, ventilation and air conditioning (HVAC) systems to provide two-position or modulating functions. This field replaceable assembly allows for in-pipe installation without the need for costly and time consuming servicing or re-piping.
The Tom Rosback Interview: A special thanks to Honeywell’s Tom Rosback. Ken and I had the chance to have a candid conversation with Tom about the changes at Honeywell, and the direction the company is headed. Tom was very open and addressed concerns, including Honeywell Spyder issues and the shake up at Tridium. As one of my teachers, a renown expert on leaders and leadership, once told me… “If everyone agrees with what you are doing you are not leading.” After spending time with Tom, I believe that he is a true leader and Honeywell and the Industry are lucky to have him.

There are many different types of valves for different applications, so how do you know which is the best to use for your application? We’ll start by looking at globe valves and ball valves. The main difference between these two types is the way they close. A globe valve uses a plug (stem) that closes against the flow, and a ball valve has a gate (ball) that closes across the flow. Globe valves are good for regulating flow, whereas ball valves are better for on/off control without pressure drop.
For many decades globe valves were considered the industry standard in control valves. They are designed with a stem that moves up and down inside the valve to control flow. They are commonly used on hot and chill water coils, and larger models are often used to control flow to chillers. One of the main limitations of globe valves is that their close-off rating can be lower than other valves, especially in the larger sizes.
Ball valves are designed with a ball inside the valve. The ball has a hole through the middle so that when the hole is in line with both ends of the valve, flow will occur. When the valve is closed by turning the ball 90 degrees, the hole is perpendicular to the ends of the valve, and therefore flow is blocked. Ball valves are very durable and usually have excellent shutoff even after years of use. They are generally preferred over globe valves in shutoff applications. The main limitation for ball valves is proportional control because of the large amount of flow that the ball allows.
Check back soon for more valve comparisons. Up next, 2-way vs. 3-way valves. Until then, I hope everyone has a Happy New Year!
