Overview

This is a genuine OEM PTAC thermostat kit for the Tempstar TEB15R25STA packaged terminal air conditioner, comprising the thermostat control (part number 1058517) and its matching control knob (part number 1058437). The thermostat senses room temperature and signals the unit to cycle heating or cooling to maintain setpoint.
