Hello, I'm having trouble understanding why my temperatures in winter are so high.What happens, is that they start at 20?C and go up to 55 ?C ( It?s crazy). My system consists in heating during winter months (no cooling available), and cooling in summer period. Can someone help me, how can i control my temperature to 20?C in Winter period. Could this happen because of the internal loads... Best regards, -- Atenciosamente: Eng?: Leandro Lopes *Tel: **965771706* N?o imprima este e-mail.
