XBOXER XBC ECOSMART (CO) MODELS
10.0 SA BUS DEVICES
10.1 ROOM MODULES
Figure 25:
Room Modules are electronic, wall-mountable sensors designed to work
directly with the Nuaire control panel.
Room modules are automatically detected and require no set-up. The majority
of RM modules monitor room temperature; however, options are available to
also monitor zone humidity, carbon dioxide (CO2), local temperature setpoint
adjustments, PIR, and other variables. This data is transmitted to a controller
on the Sensor Actuator (SA) Bus.
10.2 FEATURES
Figure 26:
Backlit LCD Display - All LCD display versions of Room Modules include a dial
to adjust room setpoint. While the setpoint is being adjusted the backlight will
switch on and the display will update to show the setpoint. While inactive the
display will revert to display the current room temperature. The occupancy
status is also displayed on the LCD. On fan speed override models the fan
speed and override status is also displayed. A maintenance icon will display if
there is a sensor network error.
Service Port - A RJ12 service port is provided at the base of each Room
Module. This allows the temporary connection of an extra module to the
sensor network.
Fan Speed Override/Room Humidity - This button cycles through fan speed
override settings.
Room Humidity - The ESC-RM-2-TDH-120 model includes a push button on
the face of the network sensor to allow occupants to view the temperature
and relative humidity of the zone. Pressing the push button toggles between
temperature and RH on the LCD. The LCD defaults to temperature 5 seconds
after the push button is released. Following this procedure to permanently
change the default display:
1. If the display backlight is off, press and release the push button to
illuminate the backlight. If the display backlight is already on, proceed
to Step 2.
2. Press and hold the push button for 5 seconds to switch to the desired
default display (either temperature or RH). Note: The desired default
display will flash for 5 seconds. After the display stops flashing, the new
default display is in effect.
3. Release the push button; the desired display is now the new default
display.
The humidity setpoint cannot change via RM sensors. This must be changed
through a commissioning tool.
10.3 INSTALLATION
Location Considerations
Locate the network sensor:
l
on a partitioning wall, approximately 5 ft (1.5 m) above the floor in a
location of average temperature
l
away from direct sunlight, radiant heat, outside walls, outside doors, air
discharge grills, or stairwells; and from behind doors
l
away from steam or water pipes, warm air stacks, unconditioned areas (not
heated or cooled), or sources of electrical interference
To remove the rear cover
1. Use a pozi screwdriver to loosen the screw on the top of the unit.
2. Insert a coin into the slot next to the security screw location, pressing the
tab that keeps the unit closed. Then carefully pry the top edge of the sensor
assembly away from its mounting base and remove.
Modular Jack:
For the modular jack, simply snap the wiring plug into the jack. A modular jack
requires a straight-through, one-to-one connection (not a crossover).
See interconnection section for details.
