When the SW9-LINK button is pressed, the thermostat will
display a “Please Wait” message (see Figure 11) in the bottom
right corner of the LCD while it searches for a node. You have
several seconds to initiate a Link Service Request at the control
node. Often it is easiest to have the thermostat in your hand
while you are near the node. The thermostat will link with the
first node it hears that indicates a Link Service Request. It is
for this reason that multiple installations must be coordinated.
(see note in Installing Nodes section.) Once the thermostat finds
a node, linking information is exchanged, the “Please Wait”
message is extinguished, and a “Good” message will appear
as shown in Figure 11.

If another node is to be installed to this thermostat, press the
HEAT/COOL button again. The “Install” icon will flash. As
was done previously, press the HEAT/COOL button (Step Two).
The node number will begin blinking, select the node number
by one using the UP button and continue with the remaining
steps. When all nodes are installed, press the SW4-INSTALL
button to close the installation session and return to normal
thermostat operation.
If for any reason there was a problem encountered during
the final installation and linking step, a “Bad” message will
be displayed. If this happens, repeat the “Installing Nodes”
process from the beginning. If the problem persists, perform
a “Thermostat Installation Reset” on page 14 and repeat the
“Installing Nodes” process.
