Tempstar PTAC Thermostat for TEB15K34SPA — 24V Control with Knob | Ships Today

Overview

This is the genuine OEM PTAC thermostat for the Tempstar TEB15K34SPA, supplied with the thermostat body (OEM 1058517) and matching control knob (OEM 1058437). The thermostat senses room temperature and tells the unit's 24V control circuit when to start and stop heating and cooling, holding the space at the set point. When it fails, the unit commonly runs without cycling off, short-cycles, or stops responding to the dial. Fitting the correct OEM control restores accurate, reliable temperature regulation.
