[font=Century Gothic][/ΗHello
i amnot sure I should be addressing the forum in English...it is my first time...so please accept my apologies!

My question: Can the time units be different for each appartment? i.e. canit be 1unit/5minutes for one and for another 1unit/10minutes etc.
Shouldn't they all be the same since these time units indicate the time our thermostats are open/ that is the time during which we profit of the hot water or heating?
αλλεςμοναδες πεφτουν κάθε 5 λεπτα και άλλες κάθε 10, για περίπου όμοια διαμερίσματα, είναι ομαλό;

please explain...
