User Interface
Ind Fan Occupcy
The Ind Fan Occupcy is the option that decides the indoor fan
function. It includes the following options.
• Continuous
• Auto
• Cont. when occup.
Continuous is used if it is desired that the fan runs all the time
regardless of Effective Occupancy. The Auto option allows the
fan to cycle with the heat or cool call regardless of Effective
Occupancy. The "Cont. when occup" option lets the indoor fan
run continuous when Effective Occupancy is occupied.

Temperature Screen

The temperature screen shows all available temperature
readings in the system. If any sensors are not available, the
control will either show "Sensor shorted" or "Sensor open"
messages.

Set Points
Set point is the desired temperature of comfort. The user has
two ways to adjust the set point: (a) using the User interface, or
(b) sending a command through the network. The set point
selection will only be valid when the board is not connected to
a thermostat.
The user can select occupied and unoccupied set points for
both heating and cooling through either the display or the
network. The selection through display does not allow the user
to choose set points closer than the value of the dead band plus
differential, so the control automatically changes the value of
the set point not being adjusted. As an example, if the
differential plus dead band equals to three degrees and the user
is adjusting cooling set point at 72°F, the control will lower the
heating set point to 69°F if the difference between the two is
less than three.
If the remote set point adjustment is enabled, then the control
will consider the hardwired potentiometer input to determine
occupied set points only. If the remote set point adjustment is
enabled but the input reads an invalid number, the control will
default back to the occupied set point selection.
Network data takes precedence over local selections. In other
words the control will follow a valid remote set point
adjustment from the network, even if the remote set point
adjustment is enabled and the hardwired input reading is valid.
The DDC Controller will consider the hardwired
potentiometer reading or the network remote set point
adjustment as the cooling set point. It calculates the heating set
point by subtracting dead band (2.0°F) and differential from
the cooling set point.
Cooling Differential, Heating Differential, and Dead
Band
Differential is the maximum difference allowed between the
temperature reading and set point before the control considers
a valid demand for cooling or heating. The differential is also
valid for determining that the unit has satisfied demand.
Depending of the mode of operation, the differential will either
be added or subtracted from the set point to determine those
points.
Dead band is the difference between cooling set point minus
cooling differential and heating set point plus heating
differential.
