It includes the thermostat assembly (OEM part 1058517) and the matching control knob (OEM part 1058437). The thermostat senses room temperature and cycles the unit's compressor and fan to maintain the setpoint selected by the occupant. In PTAC applications — hotels, multifamily units, sunrooms, and light commercial spaces — a failing thermostat is one of the most common causes of comfort complaints. Symptoms of a worn thermostat include the unit failing to turn on or off at the dial setting, short cycling, a knob that spins freely or feels gritty, and temperatures that drift far from the selected setpoint. Replacing the OEM thermostat restores accurate, dependable control without the cost of a full chassis swap.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Numbers\u003c\/td\u003e\n\u003ctd\u003e1058517 (thermostat), 1058437 (knob)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003ePTAC mechanical thermostat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTempstar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl Voltage\u003c\/td\u003e\n\u003ctd\u003e24V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFit\u003c\/td\u003e\n\u003ctd\u003eOEM direct replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003ePackaged terminal air conditioner\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for the Tempstar THB07R34STA PTAC chassis.
