Overview

This genuine OEM PTAC thermostat and knob assembly serves the Tempstar TEB09K34STA, combining the control thermostat (part 1058517) with its matching knob (part 1058437). The thermostat senses room temperature and cycles the compressor and electric heat to maintain your setpoint on this 24V control circuit. A failed thermostat is one of the most common reasons a PTAC unit runs nonstop, never reaches the set temperature, short-cycles, or stops responding to the dial entirely.
