Tempstar PTAC Thermostat for THB07K34STA — 24V Control with Knob | Ships Today

Overview

This is the OEM PTAC (Packaged Terminal Air Conditioner) thermostat assembly for the Tempstar THB07K34STA unit, including the matching control knob (OEM 1058437) and the thermostat body (OEM 1058517). The thermostat regulates the 24V control circuit, cycling the compressor, fan, and heat strips on and off to hold the room setpoint. When a PTAC thermostat fails you'll typically see temperatures that drift far from the dial setting, a unit that runs nonstop, or one that won't start the compressor at all. Replacing the thermostat as a matched knob-and-body set restores accurate temperature control and crisp dial detents.
