CONTROLLER REPLACEMENT PROCEDURES
Instructions to replace Honeywell controller using pigtail (ALL OVENS EXCEPT PS640VE2, PS740VE2,
PS745, and PS840VE2)
1. Open the control panel of the oven with the old controller.
2. Label all wires going into the Honeywell controller with associated Honeywell
terminal positions.
3. Disconnect the orange or green female terminal block from the pigtail.
4. One by one, route the labeled wires from the
Honeywell control to the terminal block poles based
on the chart to the right. Make sure ALL wires in the
Honeywell terminal are transferred to their respective
terminal block position. Some terminal block positions
may be empty, and some may have multiple wires.
NOTE: JUMPERS: Discard the jumper between
Honeywell positons L1 and 10, if applicable.
OTHER JUMPERS: Any other jumper will be rerouted
to the appropriate poles on the terminal block, jumping
two positions on the terminal block.

NOTE: L1/10: All wires connected to L1 and 10 will be routed into the same terminal pole (#1).
5. PS555E ONLY: Remove the wire connected to position 9 on the Honeywell controller. Reroute the wire
connected to position 10 to Terminal Block Pole 2.
6. Reroute ground wires into nearby chassis ground studs.
7. Remove the Honeywell controller by unscrewing the two retaining brackets
and pulling the controller out of the front of the panel.
8. Remove the plastic retaining bracket from the back of the West controller.
Ensure that the rubber gasket remains installed in the inside bevel of the
controller.
9. If pigtail is not assembled to the West controller, assemble the pigtail to the
controller by matching the wire numbers to the position on the West controller.
To facilitate insertion into the control panel, do not connect wires 22 and 24.
10. Insert the pigtail and controller through the square hole in the control panel. If
wires 22 and 24 have been connected, disconnect to allow the controller to fit
through the square hole.
11. Assemble the plastic bracket to the back of the controller, with retaining feet
pointed away from the control panel and tighten as much as possible by hand.
12. Connect wires 22 and 24 to the matching terminals on the West controller.
13. Plug the male and female terminal blocks together.
14. Tidy wires with cable ties. Use electrical tape as needed to prevent shorts.

Proper Installation Checklist
1. Set the set point at the correct operating temperature.
2. Turn on the heat switch. Ensure the oven comes up to temperature and stays at temperature.
NOTE: HEAT LIGHT: For modulating ovens, the heat light will stay on at any effort above 0%, and will only turn off
if the set point temperature is lowered below the current temperature. For solenoid ovens, the heat light will turn on
when the solenoid is open and off when the solenoid is closed.
3. Turn off the blower switch. Ensure that the oven blowers remain running until the oven has dropped below 200°F,
after which the oven will turn off.
4. After the oven has turned off, turn the blower switch back on again. Ensure that the oven operates normally.
Troubleshooting
Error Code or Situation
Description
Troubleshooting Steps
Upper Display: or
Temperature input is out of range.
Double check that the thermocouple
wires are in the correct positions in
the pigtail as well as on the
temperature controller (WHITE in
terminal 2 and RED in terminal 3).
Upper Display:
The controller does not detect
Thermocouples.
Double check that the thermocouple
wires are in the correct positions in
the pigtail as well as the temperature
controller. Ensure the terminal
blocks are properly plugged
together.
Upper Display:
There is an internal fault in the
controller.
Turn off the power for at least 10
seconds, then turn it back on. If error
does not clear, replace the defective
controller.
Solenoid Ovens: Solenoid is not
opening.
The Solenoid is not receiving power.
Check that parameter Pb_P is set to
0. Check that pigtail position 10 is
connected to Line voltage and
position 11 is connected to the
solenoid.
All ovens: A relay is not working
(cooldown relay, heat relay, high limit
relay)
The relay is not receiving power.
Check that any jumpers (except L1-
10) were transferred to the terminal
block.
NOTE: If GoTo ConF displays after power is cycled:
a. Turn the blower switch to start the oven without heat.
b. When “GoTo ConF” displays, press the Scroll key to enter the Unlock
Screen.
c. Press the up key to enter the unlock code (“20”), then press the Scroll key
to proceed.
d. Press the scroll key 20 times to scroll through the entire list of parameters.
e. Hold the Star key for 3 seconds to return to the Operator screen.
f. “GoTo ConF” should not return.

The units will switch between Fahrenheit and Celsius.
PROGRAMMING ADJUSTMENTS
Locking and Unlocking Set Point
The Set Point can be locked so that it isn’t changed
during operation. Press the Star key for 3 seconds, then
use the Scroll key to choose Set Point Lock. Use the Up
and Down keys to turn the Set Point Lock on and off.
Press the Star key for 3 seconds to exit.
