2 GENERAL DESCRIPTION

2.1 STANDARD FEATURES

GENERAL DESCRIPTION

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 or 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 onboard data collection allows for historical review, sub-metering, and run-time reporting.

STANDARD FEATURES

Energy Savings

Efficient Equipment Restart™ randomizes equipment and starts to minimize multiple units turning on simultaneously when there are multiple NetX thermostats at the location
Random Restart on power-up staggers restart of the HVAC system after a power outage to minimize peak inrush current
Adaptive Recovery for Schedules allows the system to achieve the desired setpoint at the beginning of the schedule
