Connect the Wallstation to the Control Link.
Connect two 1.0 mm
2
(#22 AWG) shielded, twisted pair
wires to terminals 3 and 4 of the wallstation’s control link
connector. Shielding (drain) of the twisted pair wires must
be connected together as shown, but do
not
connect
the shielding to earth/ground or the wallstation and do not
allow it to contact the grounded wallbox.
Note:
Use the wire connector required by local code
(those shown are common in the US).

Connect the Wallstation to external contact
closure inputs (optional).
If using one contact
closure input, connect the input to terminal A of the
wallstation sensor/contact closure input connector. If
using two contact closure inputs, connect the inputs
to terminals A and B. Connect the common side of
the contact closure inputs to terminal C.
Contact Closure Input Wiring
Notes for Contact Closure Inputs:
Verify compatibility of external contact closure input
devices. The contact closure inputs can be used
with either dry contact closures or ground-referenced
solid-state outputs. The outputs must stay in the
closed or open states for at least 40 msec in order
to be recognized by the wallstation. If there is any
question as to whether the device is compatible with
these specifications, contact the manufacturer.
Contact closure input function is determined by the
programming of the top and bottom buttons of the
left column of the wallstation.
