When contacting the factory for technical assistance, make sure you have the informa-
tion documented from the following prompts. All prompts in this menu are read only.
Date: This prompt represents the date the final control test was performed. The first
two numbers are the week (01 through 52), and the last two numbers are the year.
Software Revision: Signifies the control software revision.
Serial Number: Represents the control serial number. The first two LED’s in the
upper display are Sn followed by the serial number. The number is six digits in
length beginning with the last two digits in the upper display, and wrapping around
to the lower display where the remaining four digits are shown.
Ambient Temperature: The ambient temperature at the Input 1 terminals, in
°
F.
Acnt, gnd, cnt1 and cnt2 are for factory use only.
itY1, itY2, OtY1, OtY2, OtY3, and OtY4 are input and output module types respec-
tively. Below is a listing of the displays, and what they represent. Please docu-
ment the displays before contacting the factory for technical assistance.

Display: Press the Up or Down key to change the upper display from no to YES. Each
display and LED is tested. If any display or LED is absent contact the factory.
Test Output: This prompt tests each output. As the Up or Down key is pressed, it
cycles through the available outputs. Once the corresponding LED is lit the respective
output is energized. Press the Up or Down key again to advance to the next output.
If any LED’s are non-functional, or if the outputs fail to energize, contact the factory.
Open Loop: This prompt enables open heater or shorted sensor detect, and
enables the error code function. This prompt only functions in the proportional
control mode. The error message OPLP flashes in the lower display when on is
selected and heat or cool is full ON and no temperature change has occurred over
a period of time. The time period is based on the system characteristics.
Range: on or OFF
Default:
OFF
