a
In the case of the CLLYVL0000AS, CLLYVL4022AS controllers, only,
terminals 9 and 11 (DO-3 and DO-4) are internally hardwired to the
actuator.
b
Digital outputs: Open circuit = FALSE, closed circuit = TRUE
c
Analog outputs may be configured as digital outputs and operate as
follows: FALSE (0%) -> 0 Vdc (0 mA), TRUE (100%) -> the max.
11 Vdc (22 mA)
d
UI-1* is a hybrid input. It can be configured either as a DI (fast digital
pulse meter) or as a UI.
IMPORTANT
If the controller is not connected to a good earth
ground, the controller's internal transient protection
circuitry is compromised and the function of protecting
the controller against noise and power line spikes
cannot be fulfilled. This could result in a damaged
circuit board and require replacement of the controller.
Refer to installation diagrams for specific wiring.
All controllers have terminal arrangements similar to the
examples shown in Fig. 13 and Fig. 14 as described in Table
3 and Table 4.
NEURON® Service Pin
When pressed, the NEURON® Service Pin pushbutton trans-
mits the Service Message to the network, regardless of the
controller's current operating mode (see Fig. 13 and Fig. 14).
CAUTION
Electrical Damage Hazard.
Can cause controller damage or failure.
Do not use any metal object to press the N
EURON®
Service Pin. Use, instead, a plastic rod or wooden
implement (such as a pencil with the lead broken off)
to press the pin. Using a metal object can damage the
controller's circuitry.
LonWorks Bus Convenience Jack
The LONWORKS® Bus connection is provided by plugging the
Serial L
ONTALK® Adapter (SLTA) connector into the
L
ONWORKS® Bus Jack (see Fig. 13 and Fig. 14).

Wiring Applications (Examples)
Fig. 15 through Fig. 21 illustrate controller wiring for the
following configurations.
Typical controller wiring for VAV application using the
CLCM4T111 Wall Module and an LF20 Air Temperature
Sensor (see Fig. 15).
Typical controller wiring for VAV application with staged
reheat (see Fig. 16).
