Using the Keypad/Display

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.

Changing Set Points

The keypad/display can be used to make a +/–5°F (+/–3°C) offset adjustment to the
effective temperature set point. See Figure 4. Also see "Space Temperature Set Points"
on page 26 to learn more about temperature set points.

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 +/–3°F (+/–1.7°C) remote wall sensor, any set point offset adjustment
made at the keypad/display causes the UVC to override and ignore the remote wall
sensor set point adjustment knob. To use the remote wall sensor set point adjustment
knob after you changed the set point offset on the keypad/display, clear the keypad/
display set point offset by cycling UVC power.
– 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.
