IMPORTANT NOTES:
Phase Angle:
Phase angle and phase
angle with current limit
are available on single
phase, and 3 phase/3-leg
models only. To get
current limiting, you
must also order heater
diagnostics.
Heater Bakeout:
Heater bakeout is
available on single
phase, and 3 phase/3-leg
models with heater
diagnostics.
