NETWORKED CONTROLS

Fan control
With three user modes—winter, summer, and manual—SmartSense365 can control Big Ass Fans year-round with the push of a button. Using internal temperature sensors, the control takes the guesswork out of winter fan operation by automatically adjusting a fan’s speed to minimize floor-to-ceiling temperature differential. In summer mode, fan speed increases as the temperature at floor level rises, keeping occupants cool. Manual mode gives users full control over every aspect of a fan's operation.

Variable-air-volume controller
Variable-air-volume (VAV) building-automation controllers are capable of bidirectional communication with wireless EnOcean and wired end devices. The controllers feature an embedded EnOcean transceiver and EnOcean-to-BACnet gateway, allowing total wireless control of energy-harvesting end devices within an end-to-end BACnet system. Extending the reach of centralized building-automation systems, the VAV controllers are fully programmable devices with an on-board pressure sensor capable of meeting VAV application requirements. The controllers can act as stand-alone products or be integrated into a larger BACnet system.

Digital-thermostat controllers
DTS pipe-mounted digital-thermostat controllers provide temperature control, power switching, power connection, and alarm indication for heat-trace systems used in process-temperature-maintenance and freeze-protection applications. Programmable from -40˚F to 485˚F standard, the controllers mount directly to pipe and house the heating-cable-power connection.

Controllers
For use with Daikin's VRV and SkyAir commercial systems, Navigation controllers allow for independent setback set points for cooling and heating, give users the ability to program a weekly setback schedule, and are backward-compatible. The hand-held controllers feature a backlighted liquid-crystal display and room-temperature buttons, as well as intuitive menus. Up to 16 indoor units can be controlled in one group.

Low-differential-pressure switch
Now available with a double-pull/double-throw (DPDT) switch output, Series 1831 low-differential-pressure switches combine small size with 2-percent repeatability. No power is required to operate the DPDT switch. Set-point adjustment on the switch is accessible for modification.

Redundancy control
Used when a redundant mechanical draft system is required, the EBC 25 redundancy control monitors two individual EBC 30 or EBC 35 controls and their respective variable-frequency drives, sensors, and fans. Typical uses include the control of redundant mechanical draft systems serving boilers and water heaters in hospitals, hotels, and other applications in which possible downtime during repair, maintenance, or system failure is not acceptable. The control has a visible alarm function and can switch from a primary to a secondary system automatically.

VAV systems
Delivered variable-air-volume systems provide the precise amount of conditioned air to maintain comfort and minimize electrical energy use. The systems include control and monitoring applications, such as scheduling, system summary, remote monitoring, alarm management, and data logs. The systems offer reliable control with access from any Web-based interface without additional hardware.

Controller application
Available for free download through iTunes, the meZO controller application for iPhone and iPod Touch can control Mitsubishi Electric systems remotely. The application allows users to monitor zone temperature, turn an indoor unit on or off, and set mode, temperature, fan speed, and vane direction without having to be on-site. Additionally, the application is configured through menu-driven settings that support multiple locations, multiple controllers per location, and customizable names for indoor units.

Gateways
Third-party automation systems using the tekmarNet Gateway 482 can access and set temperature control and comfort levels provided by tekmar radiant-floor-heating thermostats. The automation systems offer one interface for climate, audio, video, security, lighting, and irrigation systems. Each thermostat’s heating, cooling, fan, and mode (off, heat, cool, auto) settings are adjustable, while room and outdoor temperatures are viewable.

Sensor/controller
A BACnet-based communicating sensor/controller with a built-in humidity sensor, the TouchView offers pre-programmed universal inputs, relay outputs, and analog outputs in one unit with a user-friendly interface. As a configurable controller, the unit is suited for applications such as fan-coil units, heat pumps, and air-conditioning units in retail spaces, restaurants, offices, and places of worship. Each application supports passive infrared and space-temperature setbacks.

Rooftop-unit controls systems
Valent Air Management packaged rooftop units are designed around microprocessor control systems.
Valent controls support open systems communication to building-automation systems (BAS) through the BACnet or LonTalk protocols. For buildings without a front-end BAS, the WEB UI interface provides monitoring and control via a building local-area network and basic Web browser. System data can be viewed on a local liquid-crystal display on the unit controllers.

Carbon-dioxide sensors
CWLP Series non-dispersive infrared analyzers are designed to measure carbon-dioxide (CO2) levels in indoor spaces. With integrated BACnet and Modbus protocols, the sensors connect to a facility's automation system, alerting when CO2 levels are too high and triggering the system to allow an inflow of fresh air to stabilize the environment. With a measuring range of 0 to 5,000 ppm, the CO2 sensors are configurable to multiple baud rates, allowing data to be transmitted at a speed sufficient for the automation system.
