EEPROM Update in Control Memory
EEPROM is permanent programmable memory of the
control panel.
•
Entry tone, door audio alarm and status are stored
in EEPROM after control panel is deactivated.
•
Clean coil status is stored in EEPROM after every
defrost cycle as time until clean coil alarm is
activated.
•
Information stored in EEPROM memory is not
affected by power loss.
Mode A Functions
Reading Temperature Display
Temperature display will show thermistor temperature
in binary coded decimal format (BCD). Indicator lights
1 through 4 represent the tens digit with 1 being the
most significant bit. Indicator lights 5 through 8
represent ones digit with 5 being the most significant
bit. Positive and negative are shown by indicator light
9; light glows to show negative value

3 6 Degrees F.
Add together all lit indicators
1 through 4 according to their
values to obtain tens column digit.
Example: If 3 and 4 are lit the tens
column total is 3 (2 + 1 = 3)
Add together all lit indicators
5 through 8 according to their
values to get ones column digit.
Example: If 6 and 7 are lit the
ones column total is 6 (4+2 = 6).
The coldest indicator is not lit
so example is +36 F.
NOTE: Temperature reads degrees Fahrenheit only.
Use conversion formula °C=5/9(°F-32).

Mode B Functions
Automatic Keyboard Function
Activate and deactivate keyboard by toggling
Display Off pad. If high temperature indicator glows,
keyboard will disable after 10 minutes. If high
temperature indicator is off, keyboard is always
enabled. DO NOT LEAVE KEYBOARD IN ENABLED
MODE AFTER PROGRAMMING IS COMPLETE.
