is the only model currently available. All other controllers
P/N 30871 (E)

Digital Temperature Controller with black plastic face
plate, 120-240V, selectable on-off, PID and variable
pulse modes.
Note that the dedicated variable pulse mode is used on
the PS536 electric oven ONLY. Using this mode re-
quires moving a jumper on one of the PC boards inside
the controller. The PS555 variable pulse electric oven
does NOT use this mode and should have the control-
ler set to the PID mode as described in the Kit instruc-
tions.
shown are no longer available and part numbers are pro-
vided for reference only. Servicing these units is beyond
the scope of this manual. If one of these controllers is in
need of service, we recommend simply installing a current
unit (P/N 46837, included in Kit P/N 47321).
