This guide covers Infinity and Evolution zoning and non-zoning systems with versions CESR131339-03, -

05, -06, -08, -10, and -12 software (versions 7, 9, and 11 were not put into production) . The model

There are two ways to determine the software version: enter the Service menus with a 10 second push of

the Advance button, or cycle power to the User Interface. When power is re-applied, the User Interface

will re-establish communications with the equipment and display the software version as shown below:

The first Service menu screen will show the software version near the bottom of the screen. Infinity and

Evolution systems are designed to alert the equipment owner of a potential system problem, and help

guide the servicer in determining a system problem. Two types of alerts can pop up on the User Interface

screen when a system problem or potential system problem exists. These alerts are described below.

Critical Malfunctions (software versions 3,5,6,8 only)

Certain system problems will result in the message “CRITICAL MALFUNCTION CALL TECHNICIAN”.
