Chelmsford, MA – May 10, 2012 – Introducing Millennial Net’s Wi-Stat IIIp-S - the first 100% standalone programmable pneumatic thermostat on the market which allows occupancy scheduling without an energy management solution.  It is designed for easy retrofit to existing 2 pipe pneumatic HVAC infrastructures without disruptive and expensive rewiring.  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 also will be able to control the Set Point and Set Back temperatures and configure all pneumatic settings such as action direction, set point and set back pressure values, and gain and throttling range. 

Wi-STAT IIIp-SIn addition to Wi-Stat IIIp-S standalone control capabilities, it can easily be converted to Millennial Net’s 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. Therefore, once a certain number of stand-alone thermostats are installed a wireless network can be activated by pushing few buttons on the thermostat. Once radios are activated, all devices will automatically connect to an existing BMS or web-based energy management system through a gateway without additional networking configuration.

“The Wi-Stat IIIp-S standalone programmable thermostat is a true a game changer in pneumatically controlled building retrofits” says Dieter Schill, CEO.  “We heard our customers when they told us that any retrofit project has to be budgeted and approved as a capital investment. Conventional thermostats can be replaced with Wi-Stat IIIp-S programmable devices as part of normal maintenance program, within an operation budget, without networking into a centralized system right away.  Customers can begin saving on energy costs much sooner, and later integrate into a centralized BMS.” 

Unlike conventional bi-metal pneumatic (mechanical) thermostats, the Wi-Stat IIIp-S has no mechanical parts.  It operates on totally different principles, enabling unmatched reliability, longevity and flexibility, which improve control quality and responsiveness.  It also reduces the cost and frequency of unit replacement and maintenance.  Routine maintenance and recalibration are completely eliminated.

 Several important capabilities are made possible by the wireless battery-powered Wi-Stat IIIp-S, operating as a standalone device or in a network:

- Local or over-the-air programming and adjustment
- Local or remote wireless set point control
- Programmable temperature setbacks and other energy policies
- No wiring or cable installation

PlantPROCORE Sample Wi-Stat IIIp-S units can be purchased on, larger quantities are available through Millennial Net partner network.

This and other MeshScape products and solutions are available through system integrators and contractors, globally.  To become a reseller or find a provider for your building please contact us at
