[Hallb-engineering] [New Logentry] Follow-up Re: Solenoid Magnet Reservoir Pressure Control

The EV8670BY valve had a minimum of 25% from the EV8670BY_min loop. This was changed a few days ago to 10% by Denny to keep the shield from warming too much.
I changed the Input Parameter of the PID to the warmer of the shield outlets from the Magnet (TR8672) and made the set value 43K. I also changed the DP setpoint from 0.2 atm to 0.03 so the valve reacts earlier and quicker to a fast dump and the max change from 10 to 30. 

The temperature of TR8672 overshot a bit but onle 1.7K so we will leave this overnight and probably increase it in the morning.

The goal is this is to keep the relief valve from opening during a fast dump of the Solenoid.
