It includes the genuine PTAC thermostat (OEM 1058517) and the matching control knob (OEM 1058437). The thermostat senses room temperature and cycles the compressor, fan, and electric heat to maintain your setpoint. A failing thermostat causes continuous running, failure to reach temperature, short-cycling, or a dead\/slipping knob. These factory-spec parts restore the original fit, calibration, and 24V control behavior of the unit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\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\u003eThermostat Part Number\u003c\/td\u003e\n\u003ctd\u003e1058517 (TSTAT PTAC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKnob Part Number\u003c\/td\u003e\n\u003ctd\u003e1058437 (KNOB TSTAT PTAC)\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 (Heil \/ ICP)\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\u003eFits Model\u003c\/td\u003e\n\u003ctd\u003eTHB07K25SPA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eEngineered for the Tempstar \/ Heil \/ ICP THB07K25SPA PTAC unit and other THB07K25 series PTACs that share the same thermostat platform.
