[EnergyPlus_Support] Way to interprete the moisture load rate in the output file

Hello All

Just some background, my model has dual humidity setpoints such that the humidifying setpoint is 33(%) and the dehumidifying setpoint is 69(%). The output file came out after running my model, displaying three measures such as: (1) Zone/Sys Moisture Load Rate Predicted (2) Zone/Sys Moisture Load Rate Predicted to Humidifying Setpoint (3) Zone/Sys Moisture Load Rate Predicted to Dehumidifying Setpoint.

However, I run into a difficulty in understanding those aforementioned three measures. For example, if the case is the same as described below, what implication can I get from the results?

(1) Zone/Sys Moisture Load Rate Predicted: -0.00118 (kg_water/sec)
(2) Zone/Sys Moisture Load Rate Predicted to Humidifying Setpoint:
    -0.11435 (kg_water/sec)
(3) Zone/Sys Moisture Load Rate Predicted to Dehumidifying Setpoint: 
    0.02154 (kg_water/sec)

where, isn't it that (1) should be the sum of (2) and (3)?

In addition, is it right if I try to convert these kg_water/sec values into energy consumption? Somehow, I think I can make it because dehumidifying or humidifying equipment may need the electricity consumption. Am I correct? If so, please let me know how to convert them. 

Thank you in advance
Ahrong
