Overview

This OEM PTAC thermostat kit for the Tempstar TEB15K50STA includes the thermostat control (part #1058517) and its matching adjustment knob (part #1058437). The thermostat senses room temperature and commands the packaged terminal unit to heat, cool, or run the fan. In high-cycle environments like hotels and apartments, PTAC thermostats wear out — contacts pit, calibration drifts, and the unit begins to short-cycle, run nonstop, or fail to start. Installing a fresh thermostat and knob restores precise temperature control and dependable comfort.
