Overview

This OEM PTAC thermostat assembly is the temperature control for the Tempstar TEB12R50SPA packaged terminal air conditioner. It bundles the thermostat control knob (OEM 1058437) with the PTAC thermostat body (OEM 1058517), giving you the complete user-facing control interface. The thermostat senses room temperature and signals the unit's compressor, fan, and reversing valve to cycle heating or cooling. When this control fails, the unit may run continuously, fail to start, or ignore setpoint changes entirely. The knob and thermostat ship together so technicians replace the full assembly in one visit rather than chasing intermittent contact problems.
