How to solve "Inside surface heat balance did not converge with..." error?

I have an Energy Plus file with the following warnings in the .err report:

* Warning * Inside surface heat balance did not converge with Max Temp Difference [C] =2.059E-003 vs Max Allowed Temp Diff [C] =2.000000E-003

I'm doing the simulations considering PCM surfaces and timestep of 20/per hour (research recommendation) and ConductionFiniteDifference in the HeatBalanceAlgorithm object.

I would like to know how to solve the problem and this problem directly interferes with the results.
