8 Page 8 User Interface Changing Setpoints The KE2 Evap OEM board has multiple methods of user input. Most controllers ship with the Basic Display. This display uses KE2 Therm s familiar menu structure to allow service technicians to change the major setpoints. The setpoints may also be accessed using the controller s webpages. Pressing holding the button will enter the Setpoints menu. Press button to toggle between setpoint value. The arrows move the user through the available options for the Variables Menu. If alarms are present, they will be displayed can be viewed using the up down arrows. Pressing holding the button will enter the Setpoints menu. The button is used to save an input option when it has been changed. The button must be held for 3 seconds, to prevent accidental changes. Changes may be discarded by waiting, to allow the controller to time-out return to default screen, or by pressing the BACK button. The BACK button is used to return to the previous screen. Pressing the BACK button several times will return the controller to the default view. Controller Setup Upon initially applying power to the controller, the controller will initialize, then automatically enter Introduction Mode. The Introduction Mode consists of four Types of Control options: Ed - Electric Defrost with Mechanical TEV EdE - Electric Defrost with Electric Expansion Valve Ad - Air Defrost with Mechanical TEV AdE - Air Defrost with Electric Expansion Valve Step 1 - Using the arrows, moves the user through the available Types of Control options. Once the preferred option is displayed press hold the button for 3 seconds. Note: For mechanical valve control, Ed Ad options, setup is complete. For Ede AdE control options continue to Steps 2 & 3. Step 2 - Next, the controller prompts for the Expansion Valve Type, displays rs (RSV). If you this is the correct selection, press hold the button for 3 seconds. If not, use the or arrow to move to the correct valve. With correct electric valve displayed, press hold for three seconds. Note: Custom valve setup is not available from the Basic Display. Step 3 - The controller now prompts for the Refrigerant Type displays 404 (R-404a) as the default. Change this value by pressing the or arrow. Once you have the correct value, press hold for three seconds. These are the only setpoints required to begin controlling the system. Additional Setpoints For the majority of users, the Basic Display will provide the necessary parameters to setup the controller. From the default display, pressing the arrows will cycle through the Variables menu. The button will toggle between the variable name value. When the parameter value is displayed it may be changed by using arrows, buttons. The arrows will increase or decrease numerical values, will scroll through the available options, on the non-numerical setpoints. Pressing holding the value. To abort changes pressing the viation. button for 3 seconds will save the displayed BACK button will return the parameter abbre- Manual Valve Control Pressing holding the BACK button will put the EEV in Manual Control arrows will control the valve opening. will advance mode. to the next digit, BACK will exit this mode. Manual Defrost Pressing holding the Defrost (next mode). BACK buttons will put the controller into Diagnostics Mode The KE2 Evap OEM has been programmed with a diagnostics mode. When activated, the controller energizes each relay for 60 seconds. When the compressor relay is on the EEV will regulate to the Superheat setpoint. Display Firmware BACK Pressing holding all 4 buttons ( display s firmware revision (dir Display Revision) )will show the Display Options Simultaneously pressing holding the dress of the display (reserved for future versions). arrows will show the ad- Web Login The User Name Password are required when accessing the controller using the webpage.
