Leaving JAC Heater on overnight

Jennie W,

Since Daniel put in a TEC controller for the JAC temperature servo we will no longer use the current version of the guardian control loop so I have set JAC_HEATER guardian to SERVO_OFF. The TEC is turned on and the set point is at 25.4 Degrees C.

The servo controller can be reached by going to sitemap->IOO->JAC Overview->Controller. To turn it off select the 'OFF' button in the top right corner of the controller. The loop can be measured by using the excitation button noted in the picture.

I will trial this over the weekend so I can double check it doesn't drive the JAC away from the control point.
