4. Example Setup
Once the thermostat has been wired and secured to the control panel door, turn the power on. The display will show “GSI
Group, LLC” for approximately ten seconds while the thermostat is booting. The next screen will display “No Operation”,
provided this is the first time the controller has been used.
1. Press and hold the “SET” button until the configuration menu appears, approximately five seconds. You can press
and release “UP” or “DOWN” to navigate through the menus. Since “No Operation” is selected, the menus are
limited to “Operation Selection” and “Save and Exit”. Once an operation mode is selected other than “No
Operation”, more menus will be available depending on the mode.
2. “Operation Selection” is the first menu that is displayed in the configuration menu. While “Operation Selection” is
visible, press and release “SET” to enter the menu.
3. Press and release “UP” twice, or until “Dryer / TopDry” is displayed. Press and release “SET” to accept the
operation mode and return to the list of menus. You can now scroll through the menus to see the options that are
available for that mode of operation. Refer to Section 3.2 for an explanation of what each menu controls. Scroll
through the menus until “Exit and Save” is visible and press and release “SET” to save and exit the configuration
menu.
4. The controller should now display the default screen for “Dryer / TopDry” (Figure 7 and 8). Press and release the
“SET” button to enter the “Temperature Setpoint” menu. Use the “UP” and “DOWN” buttons to adjust the setpoint
to the desired temperature. Holding “UP” or “DOWN” will change the temperature rapidly. Once the desired
setpoint is displayed, press and release “SET” to accept the new setpoint.
5. The controller is now setup and ready to go. Refer to Section 3.3.3 for the behavior of the controller in this mode.
