Connect the Orange wire from the SMRT-Y
to one of the 24 VAC terminals on your
controller. In order to determine which of
the 24V terminals to connect the Orange
wire to, touch the Orange wire to each of
them with the controller powered on (AC
adapter plugged in). Use the terminal which
activates the SMRT-Y display (see Figure 8).
!
NOTE:
Be sure to unplug the power
once you determine the correct 24V
terminal. Do not disturb the power
supply wires connected to these
terminals. Leave them connected as
they are.
Unplug the AC power supply and secure the
Orange wire in that terminal along with the
existing wire. (Some controllers have a terminal
marked ‘TEST’ or ‘HOT SPOT’ that can be used to
connect the Orange wire.)
