Tempstar PTAC Thermostat for TEB15K34DCA — Low-Temp Control with Knob | Ships Today

Overview

This is a genuine OEM PTAC thermostat assembly for the Tempstar TEB15K34DCA air handler, including the low-temperature thermostat control (part 1059022), the PTAC thermostat (part 1058517), and the matching control knob (part 1058437). The thermostat senses room and supply-air temperature and signals the unit's control circuit to call for heating or cooling. The low-temp variant is designed to protect the system in cold-climate installations by managing operation at reduced setpoints. When this component fails the unit may run continuously, fail to cycle, or stop responding to the knob entirely.
