STEP 6 — CONFIGURE EQUIPMENT FOR FIELD-
INSTALLED SENSORS
Navigate to the Sensor Configuration screen (Main Menu
System Config
Sensor Config). Review the sensor listing and
enable or configure any field-installed sensors. See Fig. 74 for
Sensor Configuration screen layout. When finished, click the save
changes button
at the bottom of the page.
NOTE: Configuration changes may require a reboot for the
change to take effect. Press the reboot button to reboot the
controller.
Field-installed sensors must be configured to match applications
requirements. For example, if the cool/heat demand source is con-
figured for SPT and a network SPT input is not used, then the sen-
sor configuration for SPT must be enabled for the system to read a
local sensor.
If using a network sensor, the local sensor point does not have to
be enabled in the sensor configuration. For example, if the cool/
heat demand source is configured for SPT and a network SPT in-
put is used, the local SPT does not need to be disable. However,
best practice is to have a local sensor as backup, in the event of
network communication issues. In that case, the local sensor must
be enabled. If both a local input and network input are valid, the
system will prioritize the network input.
See Table 13 for a listing of commonly used sensors by applica-
tion. All devices in this screen are disabled by default, except
when the device is included as a factory-installed option (from
model number). NOTE: Sensors that are standard on all units
(RAT, OAT) will not be listed in the sensor configuration.
STEP 7 — CONFIGURE INDOOR FAN
Navigate to the Indoor Fan Configuration screen (Main Menu
System Config Indoor Fan Config). Configure the indoor
fan operation and operating speeds based on application require-
ments. See Fig. 75 for indoor fan configuration screen layout.
When finished, click the save changes button
the screen.
The indoor fan operation, including the control type, occupied op-
eration, and unoccupied operation, and indoor fan speeds must be
configured to match application requirements. See Table 14 for in-
door fan control configurations by application.
NOTE: Fan speed configurations are in % of maximum operating
speed (
). Review the unit submittal or the fan tables in the
rpm
product data to identify the required operating rpm to achieve the
applications airflow. The maximum fan speed is typically
2000 rpm for medium static fans, and 2200 rpm for high static
fans.
For example, if a unit has a medium static motor (2000 rpm max.)
and the fan needs to operate at 1500 rpm to achieve the design
cooling and heating airflows, the associated max./high fan speed
configurations should be set to 75% (1500/2000 rpm).
