UIM and Relay Board Status Indicators
The UIM and relay board have two visual status indicators. The red status indicator is always active when either
board has power. The green status indicator flashes when communications are operating and is off when communi-
cations cease. The status indicator on the UIM does not operate in standby mode. In standby mode the relay board
status indicator blinks approximately every two seconds.
7” Display - Transitional and Contemporary
Brightness is adjustable by the software and by the user from 0% to 100% in 5% increments.•
User setting of 0% is equivalent to 2% of the actual display brightness.•
Will not allow condensation on the display from opening of the oven door to be recognize as a key press and will•
not give any feedback.
7” Display - Professional
Is the same as the Contemporary and Transitional models•
Will not allow for mode selection through the GUI. Mode is only intended to be set though the mode knob.•
Cooling Fan
The fan speed at low, medium, and high is determined by the relay board software.•
The current relay board software version is 3.0.4.0.•
Operated by triac and detected during operation by voltage sense.•
Is settable for high, medium and low speeds by a stored setting in memory.•
Speed range is settable from 0 to 15.•
Has a separate set of parameters for when the oven is cooking and for when the oven is off.•
Single oven at 240 VAC and 60 Hz: Low speed is 9; medium speed is 12; and high speed is 15.•
Upper and lower oven at 240 VAC and 60 Hz: Low speed is 9; medium speed is 13; and high speed is 15.•
Single oven at 230 VAC and 50 Hz: Low speed is 10; medium speed is 12; and high speed is 15.•
Upper and lower oven at 230 VAC and 50 Hz: Low speed is 9; medium speed is 13; and high speed is 15.•
Single oven at 208 VAC and 60 Hz: Low speed is 12; medium speed is 12; and high speed is 15.•
Upper and lower oven at 208 VAC and 60 Hz: Low speed is 13; medium speed is 15; and high speed is 15.•
On single oven and upper oven speed is controlled by RTD and relay board temperatures and the active mode.•
Each temperature sensor (in all ovens) will request a certain fan speed related to temperature.•
Runs at maximum speed when an error is detected on that temperature sensor.•
Runs at maximum speed when Dehydrate mode is active.•
Runs the highest requested speed from any temperature sensor.•
Runs while door is open on single and upper oven.•
Stops running when lower oven door is open.•
Speed on lower oven is controlled by the lower RTD and the active lower mode.•
Upper and lower oven will run at the highest requested speed of the three temperature sensors when the upper•
oven RTD is greater than 550° F.
Will resume independent operation when the RTD sensor of the upper oven falls below 545° F.•
Configuration memory has a Low Fan On temperature, a Low Fan Off temperature, a Medium Fan On tempera-•
ture, a Medium Fan Off temperature, a High Fan On temperature, and a High Fan Off temperature for each sen-
sor in the system.
Temperature settings are enforced by the UIM software and have this relationship between temperatures:•
Low Fan On < Medium Fan On < High Fan On•
Low Fan Off < Medium Fan Off < High Fan Off•
Low Fan Off < Low Fan On•
Medium Fan Off < Medium Fan On•

performed regardless of the voltage detected at power up. The following tests are performed at initial power up:
1. POST
2. Detect input voltage and input frequency.
3. Detect single/double oven status.
4. If detecting 60 Hz input, then set to default US units and English language.
5. If detecting 50 Hz input, then set to default metric units and prompt for language selection.
6. Display set Time Of Day (TOD) screen for 5 minutes then go to Idle mode.
Showroom Power Up
The showroom power up sequence is performed when the unit is turned on in showroom mode:
1. Detect input voltage and input frequency.
2. Detect single/double oven status.
3. Display set TOD screen for 5 minutes then go to Idle mode.
Sabbath Power Up
The Sabbath power up sequence is performed when the unit is turned on in Sabbath mode. The display shall remain
blank during the Sabbath power up sequence:
1. POST
2. Detect input voltage and input frequency.
3. Detect single/double oven status.
Normal Power Up
The normal power up sequence is performed at all other power ups:
1. POST
2. Detect input voltage and input frequency.
3. Detect single/double oven status.
4. Display set TOD screen for 5 minutes then go to Idle mode.
Power Down Mode
This mode is activated when the power supply detects a drop on the incoming power. During this time the system
saves the TOD and writes out to flash memory any statistics buffered in RAM. The controls will conserve power to
keep the minimal system alive during this mode. The display and oven elements do not operate during this mode.
The safety systems are not compromised while in this mode. If the incoming power is not restored after the system
completes the shutdown procedure, the controls will enter a reset state. If the incoming power is restored before the
system completes the shutdown procedure, the controls will resume the previous mode.

Dehydrate Mode
Is a cooking mode that operates with the door open and requires special exceptions.•
Operates the convection fans with the door open.•
Operates the heating elements according to the algorithm in factory settings with the door open.•
Cooking Stages - Except Broil
The cooking stages in each mode control the element relays. A cycle last 60 seconds and then repeats until that
stage moves to another stage. The time listed for each element or fan lists the time that component operates in the
60 second cycle. Target temperature is the actual temperature that the lower band or high band is aiming for. For
example: a set point of 350° F, and Target Temperature of 20° F below the set point means the lower and/or high
band is opening the relay at 330° F. Call For Heat (CFH) Temperature is the number of degrees below target tem-
perature that cycles the element on. Target Temperature cycles the element off. For example: a Target Temperature
of 330° F, and a CFH temperature of 5° F, means the element relay will close at 325° F and open at 330° F. After
preheat is complete, logic shifts the cooking stage to lower band or high band. Recovery stage CFH is the temper-
ature determined by the equation (Set Point Temperature + Offset Set Temperature - CFH Temperature + Recovery
Offset Temperature) = Recovery CFH Temperature. Recovery shifts back to Lower or High band at Target tempera-
ture.
Example Roast Mode with a Set Point of 350° F. Target Temperature is 40° F above the set point (390° F). CFH
Temperature is 3°. Recovery CFH Temperature is 27° F above set point.
1. Pre-Heat 1 stage is room temperature to 80° F below set point:
Pre-Heat 1 will run from room temperature to 270° F.
2. Pre-Heat 2 stage is from 80° F below set point to set point:
Pre-Heat 2 will run from 270° F to 350° F.
3. Lower Band stage has an offset of 40° F above set point and CFH temperature of 3° F:
Target temperature is 390° F. Element on at 387° F and off at 390° F.
4. Recover stage CFH temperature is 27° F above set point: 350° + 40° - 3° + (-10) = 377°
Element on at 377° F and off at 390° F.
Each cooking mode (except Broil) shall contain one or more of the following cooking stages:
Preheat One
Is only active before the cavity reaches the set temperature.•
