X5N-NX (Replacement Only)

XBus™ Wired Communicating Thermostat


    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 in-rush current

    The X5N-NX is a communicating setback color touchscreen thermostat designed for new or replacement commercial or residential applications. Our integrated logic for both conventional and heat pump applications may be configured for up to three (3) stages of heating and two (2) stages of cooling with an advanced remote sensor bus. The X5N-NX is a direct replacement for the US32-NX, GE22-NX, HP32-NX GE11-NX, HP21-NX, SST1, MST1, HPT1, and HPT2 models. 

    The X5N-NX is designed to operate as a stand-alone unit or be controlled using any NetX™ network controller and the NetX™ Command Center software. For maximum security, the X5N-NX may be controlled and operated behind your firewall. For ultimate control over energy usage, the X5N-NX offers a digital lockout that permits limited temperature overrides based on your requirements. The advanced remote sensor bus allows up to 6 indoor remote sensors, a humidity sensor, an outdoor sensor, and up to 3 auxiliary sensors for needs such as supply air, return air, water temperature, walk-in freezers and refrigerators, and any other temperature monitoring desired.
