Installers and Homeowners
This thermostat suits technicians and owners who need multi-stage heating and cooling management with flexible weekly programming options. It fits systems requiring terminals such as W1, W2, Y1, Y2, and humidification control. Buyers needing Wi-Fi connectivity or remote access should consider other models. Installations without a common wire may require additional wiring.
Three Heat, Two Cool Stages
The defining specification is support for three heating stages and two cooling stages. This capacity determines compatibility with multi-stage heat pumps and conventional systems. Verify your equipment matches these stage counts before purchasing. The terminal set includes dedicated connections for auxiliary heat and humidification control.

Questions about this item
What wall space does the 12 sq in display need?
The thermostat mounts on a standard wall box; the 12 sq in display sits flush once the base is secured.
Which terminals must be wired for the 3 H 2 C staging to work?
Connect RC, RH, W1 (B/O), W2 (AUX), Y1, Y2, G, C plus any sensor wires to S1–S3; missing a stage terminal disables that heating or cooling step.
When should the internal battery be changed?
Replace the coin-cell battery when the blue digital display dims or the keypad lockout resets unexpectedly.
