Page 27: Profile Heading
Profile Heading Under Profile, there are 4 Profile sections (Profile 1 Step, Profile 2 Step, Profile 3 Step, and Profile 4 Step). The steps listed under these sub-sections are a continuous list of 40 Steps that can each be individually configured into various step types to accomplish the desired profile temperature parameters. - Page 28 Step Types Time Step: The Time Step is used to change the set point of the cabinet over the specified time. This is the step type that can be used to slowly change the temperature of the cabinet at a controlled rate or can be used to change the temperature of the cabinet as fast as possible by using a short timespan setting.

Profile Examples Default Profile 1 Example Click on Profile 1 step then Profile 1 Step 1. This step is the first to use when configuring Profile 1. Note, the only options available for the Step Type (Time) are Target Set Point 1, Hours, Minutes, Seconds, Event 1, and Event 2. All others are grayed out. - Page 32 Default Profile 1, Step 3 Example Screen Default Profile 1, Step 3 Example Screen: Profile 1 Step 3 is a Wait for Event step, the Wait for Event monitors the Wait for Event 1 and 2. If either is On, the profile waits at that step until the stop button is pressed. Event 1 is On which continues to activate the refrigeration liquid, hot gas solenoid valves, and profile running indicator on the mode switch.
