Economizer Standard Sensors

OUTDOOR AIR TEMPERATURE (OAT) SENSOR— The outdoor air temperature sensor (HH57AC080) is a 10 to 20mA device used to measure the outdoor-air temperature. The outdoor-air temperature is used to determine when the Economizer can be used for free cooling. The operating range of temperature measurement is

40to 100_F (4.4 to 37.8_C). The sensor has 8 selectable temperature changeover setpoints. The temperature changeover is set using 3 dip switches on the sensor. The ABCD potentiometer on the controller should be set to the “D” position. See Fig. 39.

SUPPLY AIR TEMPERATURE (SAT) SENSOR—The supply

 

 

air temperature sensor is a 3 Kthermistor located at the inlet of the

 

 

indoor fan. See Fig. 37. The operating range of temperature

 

 

measurement is 0_ to 158_F (-17.8_to 70_C). See Table 15 for

 

 

sensor temperature/resistance values. The temperature sensor looks

 

 

 

-- A

like an eyelet terminal with wires running to it. The sensor is located

 

in the “crimp end” and is sealed from moisture.
