Overview

This is the genuine OEM PTAC thermostat (part number 1058517, "TSTAT PTAC X") for the Tempstar TEA09K34STB packaged terminal air conditioner. The thermostat is the brain of the PTAC unit — it senses room temperature and signals the unit to cycle cooling, heating, and fan operation to maintain your setpoint. When a PTAC thermostat fails, you may see the unit run continuously, fail to start, ignore temperature changes, or display erratic readings. This direct-fit replacement restores accurate, reliable temperature control without modifying the unit.
