Millennial Net Inc.: Standalone Pneumatic Thermostat
May 28, 2012
Occupancy scheduling without an energy management solution is performed by the Wi-Stat IIIp-S, a standalone programmable pneumatic thermostat. The thermostat is designed for easy retrofit to existing two-pipe pneumatic HVAC infrastructures without disruptive and expensive rewiring. According to the manufacturer, the Wi-Stat IIIp-S replaces existing manual thermostats and provides the ability to program weekday/weekend occupancy schedules previously not available for pneumatically controlled buildings without supervisory controls. Users can control the set point and setback temperatures and configure all pneumatic settings such as action direction, set-point and set-back pressure values, and gain and throttling range. In addition to Wi-Stat IIIp-S standalone control capabilities, it can easily be converted to the wireless MeshScape DDC device, which utilizes the IEEE 802.15.4 standard and 2.4-GHz radio band. Wi-Stat IIIp-S is equipped with the wireless radio module. Once radios are activated, all devices will automatically connect to an existing building management system or web-based energy management system through a gateway without additional networking configuration.
