KMC Controls

KMC Controls is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand KMC Controls rather than just read about it. In short: KMC Controls (formerly Kreuter Manufacturing Company) has designed and manufactured HVAC control system products and building automation systems since 1969. KMC was one of the early privately held controls manufacturer with a full line of digital, electronic, and pneumatic products in the United States.

Key takeaways

KMC Controls belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect KMC Controls to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of KMC Controls from memory before moving on to harder problems.

Reference excerpt

KMC Controls (formerly Kreuter Manufacturing Company) has designed and manufactured HVAC control system products and building automation systems since 1969. KMC was one of the early privately held controls manufacturer with a full line of digital, electronic, and pneumatic products in the United States. The latest products include BACnet digital controllers and thermostats. KMC is a member of the United States Green Building Council. Building automation products, such as those manufactured by KMC controls, provide tools for achieving prerequisites and credits for LEED certification in the categories of Indoor Environmental Quality, Energy and Atmosphere, Sustainable Sites, and Water efficiency for green buildings. The company's intellectual property includes patents for (pneumatic, electronic, and digital) controllers, thermostats, actuators, and valves. KMC maintains regional sales offices throughout the U.S. and distributes its products through system integrators (or authorized installing contractors), system distributors, wholesalers, and OEMs throughout North America as well as authorized distributors worldwide.

History In 1969, Ken Kreuter established Kreuter Manufacturing Company to manufacture pneumatic HVAC controls. In 1970, the company moved to Winnipeg, Manitoba because of business incentives. In 1974, the company moved to Minnesota, and, in 1978, the company moved manufacturing operations to its present location in New Paris, Indiana. In 1989, the research and development side of the business (then known as Kreuter Engineering) made the transition from Minnesota to Indiana as well in order to consolidate all company operations. In 1995, Kreuter Manufacturing Company, Inc. began doing business as KMC Controls, Inc., a name change that better reflected its business. Over the decades, analog electronic and then DDC (Direct Digital Control) products were added to the original pneumatic line.

Products

KMC Controls started with manufacturing pneumatic HVAC control products, including controllers, actuators, valves, and other related devices. A pneumatic HVAC control circuit operates on air pressure (typically between 3 and 13 psi) and uses mechanical means (actuators) to perform control functions. Pneumatic control systems are still used in many buildings, especially in metropolitan areas, because of their large base of installation throughout the 1960s and 1970s. Throughout the 1980s, analog electronic control devices became increasingly popular. They provided faster response and higher precision than pneumatics. KMC manufactures electronic sensors, variable air volume controllers, thermostats, actuators, valves, and other devices that operate from low voltage DC analog signals. In the 1990s, the standard became microprocessor-based direct digital controls that process a variety of analog and binary inputs and outputs. KMC Controls offers controllers and software in its KMDigital line using a proprietary protocol as well as a BACnet line with an open systems protocol. The BACnet communication protocol, developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), became an industry standard in the 2000s because of the desire for "open" communication systems. The 2010s brought IoT (Internet of Things) and cloud-based services to the building automation industry and KMC products. KMC Controls products and services have won a number of industry awards.

Worked examples

Example 1 — a first encounter with KMC Controls

Start with the simplest possible case. Write down what KMC Controls claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to KMC Controls before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about KMC Controls ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of KMC Controls

In research: KMC Controls appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses KMC Controls in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: KMC Controls is common in secondary-school and first-year university syllabi. It links to neighbouring topics Electronics companies established in 1969, Electronics companies of the United States, Heating, ventilation, and air conditioning companies, so understanding it makes those chapters shorter.
In everyday life: Look for KMC Controls outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
