Because of a leak in the control room the temperature control system had been switched-off during the last winter. A servo valve controlling the cooling was changed and the system is working again.
An overhaul was made of the general observing system information whiteboard in the control room. Although a lot has changed in the system, the lay-out and information had not changed much in 10 years. All the out-of-date information was removed and the lay-out accommodated to the current system as for passwords, computer names, telephone numbers, etc.
