Daikin MicroTech III User Manual

Figure 10 graphically shows the cooling reset operation. The
normal DAT cooling set point is 55.0 F. The cooling reset
scheme is set to airow. The unit is to adjust the DAT from 55.0
F to 65.0 F. When the unit is at 35% of the design airow the
discharge temperature is to be 65.0 F. When the unit is at 80%
of its airow the DAT is to be 55.0F. This example would give
the following inputs:
• Min Clg Spt= 55.0 F
• Min Clg Spt @= 80%
• Max Clg Spt= 65.0 F
• Max Clg Spt @= 35%
Based on the above, the unit will have a discharge air
temperature set point of 55.0 F from 80% to 100% of the
airow.
Unocc Diff is an adjustable item that sets the unoccupied
cooling differential.
