ADE9000 Temperature

I'm having a problem when reading the temperature from the ADE9000.

Following the guide on the User Guide, it says I have to read the values of temp gain, temp offset and temp rstl. Here are the following values:

temp gain: 18814

temp offset: 33444

temp rslt: 3757

 

The equation is: temp_rslt * ( -temp_gain / 65536) + temp_offset/32

                           = 3757 * ( - 18814 / 65536) + (33444/32)

                           = - 33.43ºC

Minus 33.43ºC is not the actual temperature so I guess either I did something wrong or the IC was not properly calibrated by the manufacturer.
