With over 15 years of design, development, and manufacturing excellence and a growing network of Authorized Dealers around the world, Reliable Controls® has become the vendor of choice for many experienced and discerning building controls managers.

Energy conservation depends greatly on how well building heating, ventilation and airconditioning (HVAC) systems are controlled to match occupant needs. In recent years, direct digital control (DDC) systems, which can easily and accurately control building HVAC systems, have become so cost-effective that they are replacing manual and electromechanical controls in retrofits, and are also being installed in almost all new buildings.

This fact sheet looks at implementing methods of controlling air systems to minimize the amount of energy used to operate fans and preheat or cool ventilation air. It addresses three key strategies:

  • Demand ventilation using carbon dioxide (CO2) and occupancy sensors.
  • Reducing reheat energy by automatically resetting supply air temperature (Enthalpy control).
  • Employing optimal start-up routines to bring space to temperature after a setback period.

    To employ these methods, systems should be equipped with an air quality (CO2) sensor, space temperature and humidity sensors installed in various locations, outdoor air temperature and humidity sensor and occupancy sensors that can feed signals back to the central control system.

    When you choose EMCS you have selected not only the simplest and most flexible building automation system in the industry today, the Reliable Controls® MACH™ System, but you have wisely partnered with a growing international corporation that is committed to long-term performance and total customer satisfaction.

    Backed by our industry-best 5-year warranty, we stand behind our products and your investment today, and tomorrow.

    We offer a complete controls solution that easily interconnects with intelligent building technology. Our products communicate using robust, industry-standard BACnet networks. The system grows with you as you grow, and has the flexibility to serve multiple simultaneous operators from numerous points of secure access.

    The goal is usually to reduce the operating cost of the building while maintaining the desired environment for the occupants.


    Maximized life cycle; retained investment; outstanding performance; exceptional value; priority access; complete control – these are just a few of the hallmarks of EMCS and Reliable Controls®. Should you or any member of your organization wish to learn more about our company, our products, or our team, please browse our our website at www.emcs.ca, or drop us a line, anytime.

    We’d like to hear from you.
