Thanks for the advice. I will discuss with our BMS emgineers. It is true that since taking over the facility we have experience these problems at lower moisture levels. You will see in my document from a previous post that we feared we had made the mine act like a sponge by drying the mine out too much. The ambient is around 10 deg c so will look at using that as the control temperature.
