Description
Product Summary

A thermostat reads the room temperature and tells the heating and cooling equipment when to run. Matching the thermostat to the system's stages, heat pump or conventional setup and power source is the key to a correct replacement. Replace a thermostat that reads the wrong temperature, will not call for heat or cooling, has a blank display or does not support the equipment's stages.
Before you order, match A19BUC-2C to the part number on the part you are replacing or in your equipment's repair parts list, and confirm the voltage, size and connections match your equipment. If you are not sure which part your equipment needs, call us at 1.888.509.3391 with the model and serial number and we will confirm it for you.
