  • Product Description

    The HP32-NX communicating thermostat is designed for new or replacement commercial or conventional residential heat pump applications where there is a need to network, remotely access, monitor and/or control settings on multiple thermostats. The HP32-NX is a 3 Heat Stage/2 Cool Stage model for gas, electric and heat pump systems. All models offer "user-friendly" control of the heating/cooling equipment along with an easy-to-read vertical LCD that displays complete operating status. An included 2-wire communications port allows complete remote control and status with a hardware adapter, internet access or telephone model dial-up. This class of thermostats represent the latest in solid-state surface mount electronics and manufacturing techniques incorporated into an extremely low-profile, ultra-slim white ABS plastic case. A direct-wire, easy-to-install sub-base mounts directly on a standard vertical outlet box or any drywall surface using hardware provided. For use with two-stage heating and one stage cooling systems. This is a direct replacement for the HPT-2.
