*Chart Notes:
1. Use the resistance column to check the thermistor sensor while disconnected from the controllers (not powered).
2. Use the voltage column to check sensors while connected to powered controllers. Read voltage with meter set on DC volts.
Place the "-"(minus) lead on GND terminal and the "+"(plus) lead on the sensor input terminal being investigated. If the voltage
is above 5.08 VDC, the sensor or wiring is "open." If the voltage is less than 0.05 VDC, the sensor or wiring is shorted.
The Duct Sensor Is Used For Sensing Supply
Or Return Air Temperatures. Location Of The
Sensors Is Very Important In Order To Obtain
Accurate Temperature Readings. The
Following Recommendations Should Be
Followed:
When Used As A Supply Air Sensor The
Sensor Should Be Mounted In The Supply Air
Duct As Close To The HVAC Unit As Possible
And Upstream Of The Bypass Damper (If
Used) For Best Results. For Best Accuracy,
Apply Insulation On The Outside Of The
Ductwork Over The Sensor. This Will Help
Thermal Gradients From Affecting The Sensor.
Supply Air
Return Air
When Used As A Return Air Sensor The
Sensor Should Be Mounted In The Return Air
Duct As Close To The HVAC Unit As Possible
And Upstream Of The Bypass Damper (If
Used) For Best Results. For Best Accuracy,
Apply Insulation On The Outside Of The
Ductwork Over The Sensor. This Will Help
Thermal Gradients From Affecting The Sensor.
See The Systems Installation And Operation
Manual For Other Design Considerations And
Recommendations Regarding Duct
Temperature Sensor Location.
