Overview
This is the genuine OEM PTAC thermostat package for the Tempstar TEB12K34DCA, including the 24V thermostat body (OEM 1058517), the low-temperature cutout thermostat (OEM 1059022), and the matching control knob (OEM 1058437). The primary thermostat governs heating and cooling cycles, while the low-temp thermostat protects the unit by interrupting operation in freeze conditions. When either control fails, the unit may refuse to start, run continuously, ignore setpoint changes, or lock out unexpectedly in cold weather. These exact-fit OEM components restore both normal control and freeze protection without rewiring.
