Viewing Actual Indoor Air Temperature (IAT)
Normally, the effective set point temperature appears on the keypad/display. You also can use the keypad/display to view the indoor air temperature (IAT). See Figure 3.
Note – When the actual indoor air temperature (Effective Space Temp Output) equals the effective set point temperature (Effective Set Point Output), you there is no change to the keypad/display when you view space temperature.

Note – The set point offset clears whenever UVC power is cycled. When you change the set point offset after a power cycle, or for the very first time, this cleared value shows as the highest allowed value (5°F/3°C) but is not an actual offset value.
–When using the
–When using the 55°F to 85°F remote wall sensor, the UVC ignores any LUI set point offset adjustments.
Menu Reference
The keypad/display menu eases troubleshooting and simplifies UVC configuration. The user can access the most common parameters and system status values without a PC or network interface.
The keypad/display menu is accessed via an unmarked, hidden key. This hidden key is located approximately behind the letter “h” in the MicroTech II logo on the keypad/display face.
The keypad/display menu consists of two levels. The first level is the keypad/display Menu Item List containing alphanumeric characters representing each parameter. The second level is where the parameter’s value is viewed and adjusted if the parameter is adjustable. After 15- seconds, an inactivity timer automatically causes the display to back out of the menu levels, returning to the effective set point display.
