Overview

This is a genuine OEM PTAC thermostat control (part number 1058517, "TSTAT PTAC X") for the Tempstar THA07R34STD packaged terminal air conditioner / heat pump. The thermostat is the brain of the PTAC unit — it reads room temperature, calls for cooling or heating, and switches the compressor, fan, and reversing valve accordingly. When this control fails, the unit may stop responding to temperature changes, run continuously, fail to switch between heat and cool, or display erratic behavior. Installing the exact OEM control restores reliable, calibrated operation without the wiring guesswork of a universal aftermarket board.

Compatibility

Always confirm the printed part number 1058517 against your existing control before installing.

Installation Guide

Safety First — Disconnect power to the PTAC at the unit cord/disconnect and verify zero voltage with a multimeter.
Access — Remove the front cover/service panel to expose the control box.
Document — Photograph all wire connections and the harness routing before disconnecting anything.
Remove — Unplug the wiring harness from the failed thermostat control and release its mounting clips/screws.
Install — Mount the new 1058517 control, reconnect each harness lead exactly per your photo, and seat all connectors fully.
Test — Restore power, set a cooling and a heating call, and confirm the compressor, fan, and reversing valve respond correctly.
