Connecting the SA918
Carefully examine the wiring that connects to your
existing thermostat. If there is no "C" wire
(common), you will need to use the SA918 Wire
Extender to connect your new SOLO thermostat to
your system.
Note: Other thermostats may have different
termination requirements.
The number of wires, and where they connect on
the existing thermostat will guide you in how to
connect the SA918.
The 3 diagrams on the previous page are the most
common for heating, cooling, and heat/cool
systems.
Newer systems will typically have a 3 or 4-wire
connection between the equipment and the
thermostat. Older systems often only have 2 wires
and require the addition of the enclosed diodes.
The single diode is connected to the SA918 "Y" &
"G" terminals with the polarity as shown.
The leads of the diode pair are typically connected
to the "C" and "W1" terminals on the thermostat
terminal block. with the polarity as shown.
The power wire, typically red, connects to the "R"
terminal while the second wire, typically black, is
connected to the screw terminal on the top of the
diode pair.
Be certain to position the diode pair housing so
that it will be recessed in the wall opening.
