Carrier HH79ZZ007 Thermister Sensor OAT

The Carrier HH79ZZ007 Thermister Sensor is an essential component of HVAC systems, it is used to accurately measure the temperature of the outdoor air. This sensor use a thermistor; a resistor that has large resistance change due to change in temperature. Depending on the temperature outside, the resistance of the thermistor in question changes in accordance with the manufacturer’s data. This change in the resistance is then translated by the control unit of the HVAC system so that fine tuning of heating and cooling operations can be effected. The sensor enables the measurement of the HVAC system and which enables the system to gain higher energy efficiency, comfort, and equipment longevity.
