Negative Temperature Coefficient (NTC) thermistor A thermistor is a thermally sensitive resistor that exhibits a continuous, small, incremental change in resistance correlated to variations in temperature. 5. HVACR Parts OEM Parts Thermostats & Sensors . Aaon P80010 Spark Wire. Honeywell W7459 Economizer and Associated Control Components 5-3. TE-205-EX TE-205-EU TE-205 (A,M,P) Space Temperature Sensors TE-205-F TE-706-B. The sensor has an operation range of -40 to 245 F. The sensor consists of a thermistor encased within a stainless steel housing with 5 in. If present, the Intake Air Temp (IAT) sensor (aka: MAT – Manifold Air Temp) is used by the ECM to tell it the temperature of the air coming into the engine. However, if the desktop halts with an “Alert! 99. 10K Type Outdoor Air Temperature Sensor. Make-Up Air Ventilators. On the Lennox L Series RTU, what is the signal that goes to the OSA damper motor? Outdoor Air Temperature Sensors . This can allow the VAVs to back off their CFM set points. Vents 1. Type . Fig. The sensor is used to monitor the equipment's supply-air temperature. Switches 1.
