TIMED OVERRIDE — The Timed Override decision is used
to configure a timed override duration by entering the number
of hours the override will be in effect. Pressing the override
button on the space temperature sensor will cause an override.
If the current occupancy period is unoccupied when the oc-
cupancy override is initiated, the mode will change to occupied
for the duration of the number of hours downloaded. If the oc-
cupancy override is due to end after the start of the next occu-
pancy period, the mode will transition from occupancy over-
ride to occupied without becoming unoccupied, and the occu-
pancy override timer will be reset.
Timed Override
Hours:
Range
0 to 4
Default Value
0
ENABLE REMOTE/FAN INPUT — The Enable Remote/
Fan Input is used to configure the remote occupancy or fan sta-
tus input. When set to a 0 the input functions as a remote occu-
pancy contact. When set to a 1 the input functions as a fan sta-
tus input.
Enable Remote/
Fan Input:
Range
0=Remote Start Input,
1=Fan Status Input
Default Value
0=Remote Start Input
BROADCAST ACKNOWLEDGER — This configuration de-
fines if the fan coil controller will be used to acknowledge
broadcast messages on the CCN bus. One broadcast acknowl-
edger is required per bus, including secondary busses created
by the use of a bridge.
Broadcast
Acknowledger:
Range
No/Yes
Default Value
No
TEMP SENSOR MODE — Each fan coil controller has the
capability to broadcast its attached space temperature sensor
data or listen to another controller’s sensor data over the net-
work. All controllers sharing the same sensor must be installed
on the same CCN bus.
There are three configuration decisions that must be config-
ured in order to share sensors. The Temp Sensor Mode is used
to specify if a controller will use its own local sensor, broadcast
its local sensor, or listen to a sensor broadcast. The Temp
Sensor Config is used to specify if the controller is sharing the
space temperature only, space temperature with temperature
offset slidebar or space temperature, temperature offset slidebar
and fan speed. The Broadcast Element # decision is used to
specify which controller number a zone will listen for when
configured to receive another controller’s broadcast.

MAXIMUM OFFSET ADJUSTMENT — The Maximum
Offset Adjustment value determines to what degree the occu-
pied heating and cooling set points can be adjusted by the set
point adjustment slide bar on the space temperature sensor.

None
Range
1 to 239
Default Value
1
UNOCCUPIED FAN CYCLING — The Unoccupied Fan
Cycling option, when enabled, causes the fan to run for one
minute each hour during unoccupied periods. The exact time of
operation is determined by the CCN address. The purpose of
this mode is to prevent air stagnation from causing the unit to
operate or not operate based upon improperly sensing the space
temperature conditions.
