Tempstar PTAC Low-Temp Thermostat for TEB15K50DCA — 24V Wall Control | Ships Today

Overview

This is the genuine OEM PTAC thermostat assembly for the Tempstar TEB15K50DCA. It includes the low-temperature 24V thermostat control (OEM 1059022), the standard PTAC thermostat body (OEM 1058517), and the matching control knob (OEM 1058437). The thermostat senses room temperature and signals the unit's control circuit to start and stop heating and cooling, holding the space at the set point. A failed thermostat is one of the most common reasons a PTAC unit runs constantly, short-cycles, or fails to respond to a temperature change. The low-temp version is built for cold-climate installs where standard controls drop out prematurely.
