Tempstar PTAC Thermostat for TEB15K34STA — 24V Control with Knob | Ships Today

Overview

This is the genuine OEM PTAC thermostat for the Tempstar TEB15K34STA, supplied with the thermostat body (OEM 1058517) and matching control knob (OEM 1058437). The thermostat reads room temperature and commands the unit's 24V control circuit to start and stop heating and cooling so the space holds at the set point. A worn or failed thermostat typically causes the unit to run without cycling off, short-cycle, or stop responding to the dial entirely. Installing the correct OEM control restores accurate, dependable temperature regulation.
