Overview
This is the genuine OEM PTAC thermostat (part number 1058517, "TSTAT PTAC X") for the Tempstar TEA09R34STB packaged terminal air conditioner. The thermostat is the control brain of the PTAC unit — it reads room temperature and signals the compressor, fan, and heating elements to cycle on and off to maintain your setpoint. When a PTAC thermostat fails, the unit may run continuously, refuse to start, ignore temperature changes, or short-cycle. Because this is an exact OEM replacement, it plugs into the existing harness and control logic without modification.

Compatibility
Engineered for the Tempstar TEA09R34STB PTAC unit. The same 1058517 control is shared across closely related ICP / Tempstar / Heil PTAC models in the TEA09 family. Confirm your existing part number or unit model tag before ordering to guarantee fitment.
Installation Guide
- Safety First — Disconnect power to the PTAC at the unit disconnect or breaker and verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the front cover/grille and the control-panel service panel to expose the thermostat assembly.
- Document — Photograph every wire and connector position before disconnecting anything.
- Remove — Unplug the thermostat harness, release the mounting clips or screws, and lift out the old control.
- Install — Seat the new 1058517 control in the same position, reconnect the harness exactly per your photo, and secure the mounting hardware.
- Test — Reinstall panels, restore power, and verify the unit responds to setpoint changes in both cooling and heating.
Signs You Need a Replacement

- Display or controls are blank, frozen, or unresponsive to button presses.
