If your Digital Temperature and Humidity Sensor is displaying wrong readings, spiking up and down or not reading at all its time to take steps in determining why the sensor is not working normally.  

 

Check sensor connection wires on the controller make sure there snug & tight.

as well as check Sensor Mapping to make sure its mapped correctly. 

1st Make sure the Sensor Self Test is DISABLED.

from home screen hit Enter/menu->SystemSetup->AdvanceSettings->

hit next till you highlight Self Test and make sure its DISABLED, if its ENABLED just hit + to Disable it.

 

 Try Landing the shielding on the GND with the Black wire and see if the sensor reading recovers.

 

Check connection’s inside junction box (if one exists) for moisture or corrosion

 

Check the line that leads to that box for cuts or any damage which will affect the sensors readings.

 

Check for wire any interference sources (High voltage, motors, inverters, VFD's etc….)

 

Check - Meter the Power Supply or even try a different 12VDC power cube, at 500mA or more, and see if dropdown voltage AC to DC is accurate, Since incorrect voltage can discourage the logic within the device.

You Also want to meter the V+ and the VOut.  Removing the wires from these locations and the Ground and simply meter the locations.

The Voltage should be between 3 & 3.5 Volts

Try toggling off switches to equip, one at a time and see if sensors stabilize.

Try detaching sensor from its current location and put it right next to controller, see if the readings recover.

If you are using generator power - or dirty power, try powering controller from a different power source location.
