With controls ranging from thermostats and zoning systems to powerful, web-based software products, Carrier places the power to keep your system operating at peak performance at your fingertips. We’re experts in helping you balance the growing need for efficiency with the consistent demand for comfort.
Also known as communicating controls or networked controls, these thermostats control common HVAC equipment such as packaged rooftop units, air handlers, fan coil units, and heat pumps. These thermostat controls are energy efficient, as they adjust the temperature according to a series of programmed settings that take effect at different times
Fundamentals of HVAC Controls Course Content Fundamentals of HVAC Controls The application of Heating, Ventilating, and Air-Conditioning (HVAC) controls starts with an understanding of the building and the use of the spaces to be conditioned and controlled. All control
The Tracer® UC400 is a programmable BACnet unit controller that is designed to work with the Tracer SC+ and third-party BACnet MS/TP systems. The Tracer UC400 has the I/O and size to meet the control needs for VAV, fan coil, blower coil, unit ventilators, small air handlers, valves, boiler sequencing, and other general I/Os.
Coil Cradles are efficient & effective systems for loading coil, threading and uncoiling medium to heavy gauge material. Cradles are available as a separate uncoiler or in combination a straightener to form a cradle-straightener. Capacities from 4,000 to 60,000 lb. and can handle widths from 12″ to 84″. Air Break “drum type” 6,000 lbs & up.
Reheat coil piping is available on 2-pipe units with hot water reheat coils and either a fan speed switch or Tracer® ZN520 and UC400-B. Control options range from a simple fan speed switch to a DDC controller that can tie into a; Tracer® Summit building automation system.

Contractor price for 3/4” auto valve with isolation valve: $60. Cost to verify flow: <5 min @ $125./hr: <$10. Manual = $77 to $97.5 Auto = <$70. It is true the initial cost of a manual valve is less expensive than an auto valve, but once labor to balance the valve is taken into consideration the total cost can be considerably more.
operating conditions. Auto controls regulate HVAC system output in response to varying indoor and outdoor conditions to maintain general comfort conditions in office areas and provide narrow temperature and humidity limits where required in production areas for product quality. Auto controls can optimize HVAC system operation.
Jul 06, 2008 · Many people wonder what Building Automation Systems (BAS) can do. The primary use of BAS is commercial HVAC control systems and energy management system applications. . Building Automation itself is an energy management system that saves management companies and building owners by efficiently controlling air conditioning and heating comfort and process s
