Honeywell Home THP9045A2098/U Wire Adapter with Magnetic Mount for Smart Thermostats

Eliminate the hassle of running a new common wire while reliably powering Honeywell Home smart thermostats with the THP9045A2098/U wire adapter. Designed for quick retrofits, this compact thermostat accessory (1" W x 2.6" H) uses easy push-terminals and a magnetic mount so technicians can secure and connect devices in minutes — minimizing downtime and labor costs. The adapter replaces the need for a C wire in heating/cooling and cooling-only systems (not for heat-only systems), providing stable DC power to connected thermostats and improving system uptime.

Built to blend into visible installs, the gray housing conceals internal components for a clean look preferred by facility managers and security integrators. Its simplicity and reliability make it ideal for HVAC contractors, building automation, and environments tied to security and monitoring systems where consistent thermostat operation matters for comfort and equipment protection. Backed by a 1-year limited warranty, the THP9045A2098/U is an efficient solution for powering smart thermostats during upgrades or when integrating with broader surveillance and building monitoring platforms. Order this Honeywell Home thermostat adapter to streamline installs and keep your smart thermostats powered and connected.
