When using a ROAM, ROAM-XL, ICR, or SRR remote, you may come across a controller that gives you an ERR or SP ERR message. There are two reasons that would cause one of these messages.
CAUSE - Noise entering the controller through the SMART PORT wiring or it is wired incorrectly.
SOLUTION - A few steps are necessary to determine the cause of the ERR message.
Check SmartPort® Wiring - If the ERR message is displayed without a device attached, check that SmartPort® wiring is correct. Make sure that the SmartPort wiring is not bundled with the field wiring or close to the transformer. The white SmartPort® wire must be attached to the terminal next to the blue wire on the REM terminal, then red above ground. See illustration to the right.
CAUSE - The remote transmitter has a maximum station count that is incorrect for that specific controller model.
SOLUTION - A few steps are necessary to set the correct station count for each controller model.
