Begin Controlling
To Begin Controlling:
1.
Apply power to the system.
A properly-wired Series 935B will begin controlling the thermal system as soon as you apply power
to it.
2.
Look at the Series 935B’s display. It is reading actual temperature, set point temperature, or time.
• To change set point, go to p. 9.
• The Series 935B will auto-tune when you tell it to, go to p. 34.
• If you see an error, go to p. 10.
