GENERAL DESCRIPTION

Complete Stand-Alone Solution

• The X7C-WIFI is a commercial grade Wi-Fi color touchscreen thermostat with an advanced remote sensor bus, designed for new or replacement applications. Use the X7C for either conventional and heat pump applications (Gas/Elect 2H/2C, HP 3H/2C), along with humidification, fresh air damper, IAQ controls and more. The X7C also includes a revolutionary CO2 sensor, with no field calibration needed for five (5) years. DirectConnect™ helps deliver a near-effortless setup of your daily schedules (4 events per day) and up to 80 Additional Events (40 Special and 40 Calendar Events). The unique scheduling structure also supports the powerful features of adjustable temporary override times and temperature ranges, occupied and unoccupied events, keypad lockout, and many more features. The X7C-WIFI also includes full BACnet/IP support over Wi-FI, directly on the thermostat.
• The X7C-WIFI is designed to operate with our CloudConnect™ Online Management software or, for maximum security, behind your firewall using DirectConnect™ or our PCConnect™ Software. Since all HVAC functions are stored in the thermostat, the X7C will continue to operate even during network outages, allowing you to maintain your energy savings.
• For ultimate control over energy usage, the X7C offers a digital lockout that can permit limited temperature overrides based on your requirements. Our on-board data collection allows for historical review, sub-metering, and run-time reporting.
