Thermostat for multi-stage HVAC systems

The White Rodgers Blue Series 12 touchscreen thermostat controls up to three heating stages and two cooling stages. It suits residential or light-commercial installations that need precise staging. The interface supports 7-day, 5-1-1-day or non-programmable schedules with zero, two or four temperature settings per day. System switching covers auto, heat, cool, off and emergency modes.

Sustained operation with programmable fan

Automatic changeover shifts between heating and cooling without manual input during long runtime periods. The programmable fan runs on a schedule or circulates air independently to maintain even temperatures across zones. Keypad lockout prevents unauthorised changes during extended use. The blue 12 sq in digital display remains legible throughout continuous operation.

Terminal layout for conventional low-voltage wiring

Connections include -, +, 6, C, G, L, O/B, RC, RH, S, W/E, W2, Y and Y2 for direct hook-up to compatible equipment. No WiFi capability means the unit operates entirely from the wall without network dependence. The white housing fits standard low-voltage thermostat locations. Mounting follows typical industry patterns for replacement or new installations.
