Michael, c'mon...
15-18C? 19C is 66F -- that's very acceptable. 15C would be 59F!
In fact, 68F (at 40% RH) is pretty "standard" for most equipment rooms.
We're config'd for a setpoint of 67F +/- 1F and 40% RH +/- 3%.
One of our more heavily loaded 7513s shows at present:
card inlet hotpoint exhaust
RSP(6) 19C/66F 29C/84F 25C/77F
That's right where it should be.
BTW, exhaust temperature above hotpoint (which your stats show) is *not* a
good thing. I'd find out what's going on there -- you may have some kind
of obstruction with the airflow.
