R = Bias resistor (with a resistance of 24.9 kΩ in the
BIAS
case of NTC10kΩ (Type II) and NTC20kΩ sensor
inputs, and 7.5 kΩ in the case of Pt1000 sensor
inputs); can be switched OFF via software by S1 to
support 0to10 V inputs without bias current (high
impedance).
R = Series resistor for voltage dividing and filtering
SER
(with a resistance of 150 kΩ).
R = An internal load resistor (with a resistance of
DOWN
49 kΩ); depending upon the given type of
connected sensor, the firmware may switch this
resistor OFF.

Analog Outputs

The terminal blocks containing the controller's analog
outputs are green. Analog output types: See Table 5 on
pg.5.
The analog outputs of the WEB-RL6N controllers (large
housing) are protected against voltages of max. 29 VAC
and 30 VDC (due to, e.g., miswiring).
NOTE: Connecting 24 VAC to any analog output of the
WEB-RS5N controllers (small housing) will
damage the hardware.

WALL MODULES

The TR40x/TR42x/CLCMx Wall Modules can be used in
conjunction with the controller to perform room
temperature sensing, setpoint adjustment, fan speed
manual override, and occupancy override. The wall modules
supported by the WEB-RS5N and WEB-RL6N are; TR40,
TR40-H, TR40-CO2, TR40-H-CO2, TR42-H, TR42-CO2,
TR42_H_CO2, CLCM1T, CLCM2T, CLCM4T, CLCM5T,
CLCM6T.
Further, the LED and LCD of the wall modules can be
programmed to provide information about:

SPYDER MODEL 5 ROOM CONTROLLERS − INSTALLATION GUIDE
▪ any override of the controller by, e.g., pressing the
"occupancy" button of the wall module or receipt by the
controller of a BACnet MS/TP network command (see
section "LED of CLCMxT Programmed to Display Info on
Overrides" below);
▪ the controller's effective occupancy mode (see section
"LED of CLCMxT Programmed to Display Info on
Occupancy" below).
NOTE: The intended use of the wall module's buttons
must be programmed using the Niagara tool.
See also corresponding Technical Literature listed in Table

Programming of Wall Module LED / LCD
The LED of a CLCMxT Wall Module can be programmed to
provide information about, e.g., overrides or effective
occupancy modes.
The LCD of the TR42x can likewise be programmed to
display such information.
LED of CLCMxT Programmed to Display Info on
Overrides
The LED of a CLCMxT Wall Module connected to the con-
troller can be programmed to indicate if an override has
been activated because either the wall module's override
button has been pressed or the controller has received a
BACnet MS/TP network command. Specifically, the
following modes are supported:
▪ NO OVERRIDE: If the wall module's LED is OFF, then no
override is currently in effect.
▪ OVERRIDE OCCUPANCY: If the wall module's LED is ON
continuously, then the wall module's override button or a
BACnet MS/TP network command has placed the con-
troller into the "occupied" or "override" mode (but if the
override button is again pushed or if a cancellation
network command is received or if the override time
expires, the controller will return to its scheduled
occupancy mode, and the wall module's LED will behave
accordingly).
▪ OVERRIDE HOLIDAY: If the wall module's LED flashes 2
sec OFF and 1 sec ON, then the controller has received a
network command and been placed in the "holiday"
mode.
▪ OVERRIDE UNOCCUPIED: If the wall module's LED
flashes once per sec, then the wall module's override
button or a network command has placed the controller
into the "unoccupied" mode (however, if the override
button is again pushed or if a cancellation BACnet
MS/TP network command is received, the controller will
return to its scheduled occupancy mode, and the wall
module's LED will behave accordingly).
▪ If the wall module's LED flashes twice per sec, then a
BACnet MS/TP network command has placed the con-
troller into either the "standby" or the "occupied" mode.

The LED of a CLCMxT Wall Module connected to the
controller can also be programmed to indicate the
