Install Where It Makes Sense
Most installs are limited by existing wiring, lack of access, and finished spaces. Boldr removes those limits by letting you install controls where it creates the most value - without new wire pulls or rigid assumptions.
The Boldr Universal Thermostat comes with a Display & Base, unlocking uncompromising install flexibility for any job site without sacrificing comfort or performance.
Simple Replacement
Uses existing wiring for a standard swap. No C-Wire adapter needed. Fast, familiar, and reliable for basic upgrades.
Install At The Equipment
Install the base directly at the equipment (furnace, boiler, heat pump, etc) and place the display anywhere in the home.
No more fishing new wires through finished walls. Solve 'broken wire' issues instantly.
Install At Air Handler
Install the thermostat base directly at the air handler to eliminate wire fishing when upgrading systems - saving time, labor, and disruption.
Perfect for straight-cool to heat-pump conversions, it enables full system control using existing wiring for a faster, cleaner install.
Wires That Adapt
Re-Assignable Terminals on The Boldr Universal Thermostat allow contractors to match the thermostat to any system and accessory they are installing. Full flexibility, built for the Pro in the field the Universal Thermostat is the only ‘stat’ you need in your truck.
