Setpoints, DIP switch settings, and other selections were made on your unit before testing at the fac-
tory. Setpoints were chosen based on typical operating experience. Other selections were made based
on options included with your unit. Make adjustments to the factory default selections ONLY if they
do not meet your specifications. When entering setpoints, time delays, etc., the allowable ranges are
displayed and may require a password, if enabled.
