The Ultra-Zone™ Internet-enabled WebStat IZT-100 and IZT-250 are Web-enabled zone thermostats. They provide the ability to configure settings through a graphical interface either locally or from any remote location. The thermostats can be connected via secure wired Ethernet to a home, small business, or light commercial data network. The IZT-100 supports an HVAC system with 24-vac power, dual-stage fuel burner (two heat and two cool), or single-stage heat pump with auxiliary heat (two heat and one cool). The IZT-250 has two remote thermal sensors - either analog or thermistor. It can be used with dual-stage fuel burner units (two heat and two cool) or dual-stage heat pump with auxiliary heat (three heat and two cool).
