Purpose:
Begin CEB heater control using the VREF temperature sensor. Switch MR control
Expected result:
The CEB will be control tightly around 3.7C. The MR warm to the current set
point of -30C then after a 6-hour delay, the set point will be lowered to
Why it is needed:
To improve detector resolution by removing some of the temperature

Why it is needed:
In order to: 1) return to mapping mode after boom deploy, 2) enable the Inner
Stage to get as cold as possible for best possible detector resolution, 3)
enhance the detector resolution as much as possible by tightening both the OS
and GPA control laws, 4) contribute more heat to the GPA from the MR so that
we may better control the GPA with the smallest heater possible (GPA 3), and
5) verify the contents of sequence 1B to know that the commands for safemode
