Figure 16, Labeled Bar Graphs
The bar chart screen is accessed from the MENU screen (Figure 12) by selecting Labeled Bar Graphs for the
graphs with labels attached as shown above or select Bar Graphs for charts without labels.
Pressing “COMP” on the lower left corner of the screen will toggle between the unit’s two compressors.
Pressing “MENU,” HISTORY,” “VIEW,” or “SET” buttons will forward to those respective screens.
SET Screens
The set screens on the Interface Panel are used to input the many setpoints associated with equipment of this
type. MicroTech II provides an extremely simple method for accomplishing this. (NOTE: If the Interface
Panel is unavailable, the unit controller can be used to change setpoints.) Appropriate setpoints are factory set
and checked by McQuay Factory Service or Factory Authorized Service Company during commissioning.
However, adjustments and changes are often required to meet job conditions. Certain settings involving
pumps and tower operation are field set.
Pressing the SET button found on almost every screen accesses the last SET screen used or the SERVICE
screen, whichever of the two was used last.
When in any SET screen, pressing the SET button again will toggle to the SERVICE screen shown on page 50.
