Siemens has a winner with the RDY2000 Thermostat

We caught up with Siemens at the 2015 CGNA Vendor Showcase. They introduced us to several cool new products. One of the ones we like a lot is the RDY2000 light commercial thermostat.The RDY2000 thermostat that has big time features for small business solutions. The Siemens RDY2000 controls more than just temperature. With ventilation, economizer, and humidification interfaces, the RDY2000 can quickly and economically solve the needs of small business customers. From coffee shops to machine shops, the RDY2000 provides the flexibility to optimize room comfort while reducing energy consumption.

The RDY2000 can do the work of several thermostats. Proving its versatility, this thermostat can control conventional systems with up to three stages of heating and three stages of cooling, as well as heat pumps with up to two compressors and up to two stages of auxiliary heat. Perfect for commercial HVAC equipment, the RDY2000 features outputs that control humidification/dehumidification equipment, maintain indoor air quality with optional CO2 sensor, maximize energy savings with interface to economizer controls, and interface with lighting systems based on business day schedule to reduce operating costs. The unit puts advanced HVAC control strategies within reach of small businesses, without the cost of a Building Automation System. The “brains” behind its beauty allow businesses to use the onboard temperature and humidity sensors or optional external sensors (up to four) to create a customized, yet affordable solution.

The best place to get more information or to purchase a Siemens RDY2000 is from one of our friends at CGNA ( Controls Group North America). Click here to locate your closest CGNA distributor and tell them “Kenny and Eric sent you.”

Why Belimo Gets it Right: Watch the Belimo Valve Test Lab Tour

BelimoBelimo’s engineering prowess and innovation set the global standards in comfort, energy efficiency, and safety solutions. This video, previewing the Belimo Valve Test Lab, gives insight as to how such unparalleled standards are set and maintained.

Belimo’s performance testing verifies that our products comply with industry and trade association specifications, including ANSI, EN, IEC, ISA, MSS, and VDI/VDE. Our testing is performed with ISO 9000 traceability.

Our performance testing provides assurance to our customers that they’ve made the right decision by choosing Belimo. Flow testing includes: equal percentage curve, pressure independent curve, and rangeability. Shell testing is performed for threaded and flanged valves up to 5,000 psi. Automated systems for flow testing improve accuracy, precision, repeatability, and efficiency. Our lab’s flow testing capacity is 6,000 GPM (with the largest pump capable of providing 3,000 GPM).

Our durability testing involves subjecting valves to 100,000 cycles at worst-case temperature and differential pressure. We have the capacity to test over 240 valves ranging from DN 10 to DN 150, with a maximum media temperature of 302°F (150°C). With 12,000 GPM durability testing capacity, we could fill one Olympic size swimming pool every hour or one standard above-ground pool every minute. We also perform Long Life testing, where the valve is subjected to application conditions for months to even years at a time.

Tim Chamblee’s Introduction to VFD’s Part 2

VFD Training Part 2: Tim Chamblee continues his Variable Frequency Drive training with an in-depth explanation of the application benefits, the potential energy savings, and the importance of proper grounding and wiring methods — and then demonstrates how to use a Honeywell Variable Frequency Drive to control a cooling tower fan with a Honeywell T775 controller.

See Why Functional Devices is a ControlTrends Community Favorite


Why is Functional Devices such a favorite within the ControlTrends Community and a go to supplier for peripheral devices? Well we can start with the really innovative cool products like the RIB ( Relay in a Box) relay.

Products made by Functional Devices are just that…functional…and price competitive….and easy to use. The PSH500A-LVC power supply fits the Functional Devices mode: it is a cost-saving, prepackaged solution for the following applications:

• Provide power to Variable Air Volume (VAV) controllers
• Provide power to zone controllers
• Provide power to controllers in critical controlled environments

The PSH500A-LVC power supply isolates the high-voltage compartment and the low-voltage compartment to prevent possible electrical hazard, eliminating the need for Personal Protective Equipment (PPE). The PSH500A is very very functional. And is another reason the world wide ControlTrends Community has nominated Functional Devices as a finalist in two categories: Peripheral Product if The Year and Vendor of The Year Small Manufacturer.
