The Unit Status screen (Figure 14) is the home page for the Control Air
M, and shows the main menus/categories of the software the user can
interface with on the devices.
Settings – For an installer, these settings allow for changes to
the device, as well as unit configuration at start-up.
Service – For a service technician, this menu allows a user to
diagnose or troubleshoot the unit.
The screen provides valuable unit diagnostic data - entering and leaving
water temperatures, states of the compressors, Reversing valve, Pump.

Occupancy Command
Under the Unit Settings screen, this parameter is used to select the
control source that will provide the occupancy command to the unit. The
options for this variable are the following:
Digital Input
Local Schedule
BAS Command
Manual Override
Throughout the setup process, by selecting diff erent boxes, this
is how you advance to the next setup screen if available, while
the back arrow is used to backtrack to previous screens.
Digital Input: The Digital Input option may be selected if the unit
occupancy is required to be controlled remotely via a switch (dry
contact) or other binary input. The connection (typically from a room
occupancy sensor) should be made in IN-1 of the controller. Choosing
this setting allows the unit to be placed in occupied mode once the
input is shorted to ground, and in unoccupied mode once the input is
opened.
Local Schedule: Schedule runs the unit on a local, modifi able
schedule, which cannot be accessed over a network. The occupancy
schedule for heating or cooling can be set according to the morning,
daytime, and night time settings for each day of the week. The option
will allow the unit to run on an 8:00 AM to 5:00 PM default schedule
everyday if the unit is to be started up during the construction phase of
the project. See the Schedule Screen for more information.
