Cooling System

The cooling system is set to cool the water to a given temperature. We have learned that this water temperature should not be too different from ambient temperature as this causes effects on the telescope encoders (likely due to thermal stress) that affects the telescope tracking. The idea is to make this automatically adjusted, but for the time being we do this manually. In particular, we change the set point between summer and winter. We now have added the current value to the data base so that at least we will be warned if the difference with the ambient temperature is too large and we have to adjust the temperature.
