Set Environmental Controls

The unit controls the environment through the use of schedules. There are 9 schedules; eight of which

are programmable, and the ninth schedule being default settings. Cooling during the times and days

for which there is no programmed schedule is done according to the default schedule (Control

Environment).

Default schedule

Path: Main menu > Control Environment.

The default schedule will control cooling when other schedules are not available or are deactivated.

Mode. The mode setting can be changed to Cool, Vent Only, or System Off. Ve nt Only will

provide circulation without cooling the room. The System Off option stops the unit and the blower,

and the Cool option engages the compressor (after a delay) and cools the room.

Set Point. The set point is the target temperature the unit will maintain in the room. The acceptable

range for set points is 60 to 90° F (15.6 to 32.2° C).

Dead band. The dead band is the range above the set point at which cooling will begin. The unit

will not begin to cool until the room temperature is at the set point plus the dead band. The acceptable

range for the dead band is 1 to 3° F (0.6 to 1.7° C).

Note

Changes to the default schedule do not override active schedules.

Note

The dead band for the system must be set at Control Environment. It cannot be set for

each schedule.
