Overview

This genuine OEM PTAC thermostat (part number 1058517) is the factory control for the Tempstar TEA15R25STA. It regulates compressor and heating operation by sensing room temperature and signaling the unit to cycle on and off. A failed thermostat is one of the most common causes of a system that won't start, short-cycles, or ignores temperature settings.
