York 5/2 Day Programmable Thermostat

The York 5/2 Day Programmable Thermostat provides basic temperature control for single-stage gas or oil HVAC equipment. It uses a 5-day weekday and 2-day weekend schedule to match typical occupancy patterns. The hardwired digital unit includes battery backup to retain settings during power interruptions.

Upgrade from non-programmable controls

Replacing a manual thermostat with this model adds automated setback periods that reduce heating and cooling run-time when the building is unoccupied. The jump is worth it when the existing control lacks any scheduling ability and the system is a compatible single-stage configuration. It does not support multi-stage equipment or heat-pump changeover logic.

Fits standard single-stage wiring

Installation requires a common wire to power the display and a 24 VAC supply from the furnace or air handler. The thermostat works with millivolt systems and most gas or oil appliances using one heat and one cool stage. It frees up the installer from configuring advanced menus but cannot drive auxiliary heat, humidifiers or multi-speed blowers.
