Energy Controls Co.: Wireless Pneumatic Switching Unit

The ecWizard is a wireless pneumatic switching device. According to the manufacturer, it is a less expensive alternative to the DDC retrofits of pneumatic systems. The device gives the building operators valuable information wirelessly back to their computers so they can diagnose and monitor their pneumatically controlled zones. It only shuts off the heating or air conditioning or it allows the existing pneumatic thermostat to control like it has for years. If the facility decides to take out the existing pneumatic system and upgrade to an all-electric system, the ecWizard will accept a module adaption and will always be compatible with future upgrades, says the company. The unit controls two specially designed pneumatic switching valves that turn off and on the control air to the end devices, which are usually existing pneumatic valves or damper actuators. The ecWizard utilizes batteries with optional energy harvesting technology.
