Controller Types This Kit includes one Digital Temperature Controller (P/N 58388) that can operate at 120-240V, and can be programmed to operate in on-off, PID, or variable pulse modes. The Controller is shown in Figure 1G, below. By following these instructions, the Controller can be installed into any Middleby Marshall oven equipped with the following Controllers. • P/N 28071-0012 (Fig. 1A) Analog Temperature Controller without high-limit and cooldown functions, operating at 120V, on-off mode only.

WARNING BEFORE PERFORMING ANY SERVICE WORK, THE ELECTRICAL POWER SUPPLY AND THE GAS SUPPLY MUST BE TURNED OFF. Before you Begin 1. This Temperature Controller requires a current-version thermocouple for proper operation. Check that the thermocouple(s) installed in the oven match the current three-lead, flanged versions BEFORE you begin to install the Temperature Controller. See Figure 2.

. Check that the new controller is mounted into its sleeve. Then, slide the assembly into the opening in the panel from the outside. Check that the controller is upright, with the display on top and the keypad on the bottom. 5. Locate the rectangular holes on the top and bottom of the new controller’s sleeve. Attach the two kitsupplied mounting brackets against the inside panel of the oven, and into the holes in the sleeve, as shown in Figure 3.

Jumper Setting Loosen the Phillips screw at the bottom center of the faceplate. Then, pull the controller out of its sleeve. Next, access the jumper shown in Figure 6. This jumper affects the signal that is output from Terminals 15 and 16. The jumper MUST be set to the correct position for proper operation of the controller. CAUTION If the jumper is incorrectly set, the oven will be unable to properly maintain temperature. In addition, DAMAGE MAY OCCUR TO THE CONTROLLER AND OTHER OVEN COMPONENTS.

Diagnostic Error Messages The controller runs background tests during normal operation. If any problems occur during the tests, an error message flashes in the display. A listing of these diagnostic error messages is shown below. Flashes on the display (alternating with the temperature) indicating that the internal diagnostic test has failed. The oven temperature has not reached 200°F/93°C within 15 minutes of startup. On gas ovens, this is usually a result of the burner not lighting.

Digital Temperature Controller P/N 46837 Operating Instructions Display Shows the Set Point or the Actual Temperature in degrees Fahrenheit (F) or Celsius (C). "HEAT ON" Light Lights when the burner or heating elements, as appropriate for the oven model, are in operation. "SP LOCK" Light Lights when the set point is locked out from changes. This setting can only be changed by service personnel. "SET PT" (setpoint) Light Lights when the set point is shown in the display.
