Product Overview
The Braeburn 1220NC is a digital, non-programmable thermostat, sold by Indiana Radiant as stock number TH-BR12. It controls up to two stages of conventional heating and one stage of cooling, or a single-compressor heat pump system with one auxiliary heat stage, and it also handles 250 to 750 millivolt heating systems. It runs on 24 Volt AC (18-30 VAC, 1 amp max per terminal, 3 amp total across all terminals) through terminals Rh, Rc, O, B, Y1, E/W1, G, W2, and C. The 2 sq. in. display has a bright blue backlight, a 45° to 90° F control range with +/- 1° F accuracy, adjustable temperature limits and differential, and low-battery indication. A front-access reset button returns all user settings to factory defaults.
The 1220NC cross-references to the Honeywell TH2210 and Emerson 1F79-111, per Braeburn's published specification sheet. It is a universal 24V room thermostat suited to any Re-Verber-Ray heater system that uses standard Rh/Rc/O/B/Y/G/W staging, rather than a model-specific replacement part for a single heater line. See the Fitment panel for the full list of compatible systems, and confirm your existing terminal count and system type against the new unit's wiring before swapping one cross-referenced thermostat for another.
It ships with a separate wall sub-base, mounting hardware, a quick-reference card, and two "AA" alkaline batteries, so it runs on 24 VAC hardwire power, battery power, or both together for backup.
Shut off power to the heating and cooling equipment before installing or swapping in the 1220NC, and match terminal labels to your existing wiring (or the unit's own installer guide) before restoring power. A 5-year limited warranty backs the thermostat. See the manufacturer's 1220NC specification sheet and installer guide for full wiring details.
