ICM/ICAD Motorized Valve			Installation, Programming, and Troubleshooting
Programming the ICAD			When the ICAD motor is "rst powered, the ICAD display will !ash an A1 alarm. This means
			that the ICM valve size that is being used with the ICAD motor needs to be selected in
			parameter ¡26. Parameter ¡26 is password protected and will not appear in the parameter list
			until the user enters the password in parameter ¡10. The password is “11,” and will allow the
			user to access parameter ¡26 where the appropriate valve size is selected. When the ICM
			valve size is selected, the ICAD will calibrate itself to the ICM valve and will then be ready for
			control by a 4-20mA signal. For most applications, this is the only programming that will
			need to be done if the ICAD is going to be controlled by a 4-20mA input.
