Millennial Net announced today the release of its 3rd generation wireless/standalone electric thermostat, Wi-Stat IIIe. It is designed for easy retrofit to existing HVAC infrastructures without disruptive and expensive rewiring. Wi-Stat IIIe replaces existing manual, analog or programmable thermostats and can support most single- or dual-stage conventional heating and cooling as well as heat pump systems.

The new Wi-Stat IIIe combines the best of two worlds:

  • It can be used as wireless thermostat in large multi-zone buildings as part of a centralized Building Automation System (BAS); or
  • It can act as a conventional digital 5/2 day programmable thermostat.

“The Wi-Stat IIIe truly stands out in a slew of networked thermostats,” says Sheng Liu, President and CEO of Millennial Net. “It is not another Wi-Fi thermostat – Wi-Stat IIIe communicates via extremely robust and already proven Meshscape® wireless mesh technology and can be easily deployed in large, multi-story buildings or can be used as your regular programmable thermostat.”

The new Wi-Stat IIIe allows for greater deployment flexibility – existing conventional thermostats can be replaced with Wi-Stat IIIe programmable devices as part of normal maintenance, without adding a full blown BAS. Building owners can begin saving on energy costs much sooner by using Wi-Stat IIIe thermostats as standalone programmable devices. Later, already installed Wi-Stat IIIe thermostats can be easily switched to wireless mode and integrated into a centralized BAS. Wi-Stat IIIe functions as Internet-of-Things (IoT) and is compatible with:

  • BACnet IP Building Automation Systems
  • Modbus TCP/IP or Modbus RTU controllers
  • Millennial Net SEMS (Standalone Energy Management Solution), a PC-based building energy management solution

The Wi-Stat IIIe is intended for use in commercial, industrial and municipal multi-zone HVAC environments to enable greater energy-policy compliance, multi-site remote monitoring and control, and usage analysis. Complex building environments, such as, office, retail, hospitality, entertainment, school, multi-unit dwellings and municipal buildings have a need for regular and ad-hoc environmental occupancy patterns. Wireless thermostat Wi-Stat IIIe allows achieving better energy conservation by aligning HVAC operation and with set points that closely match occupancy comfort requirements.

The new Wi-Stat IIIe is another addition to an already vast line of Millennial Net’s innovative Wireless Energy Management Solution products, such as the award-winning digital-wireless-pneumatic thermostat Wi-Stat IIIp, temperature sensors Wi-Zone and Wi-Temp, energy sub-meter Wi-LEM, pulse counter Wi-Pulse and many others. Millennial Net’s Wireless EMS is perfect for buildings with multiple HVAC systems, combining pneumatic and electric thermostat controls, energy, temperature, water and gas sub-metering under one single solution. Flexible and robust Meshscape wireless technology allows adding or moving devices within buildings with ease and without additional programming and configuration.
