The C-wire is used to provide power to the thermostat. If your system
does not have the "C" wire, you can use the power module to power your
thermostat using the existing wires.
There are two sides with connections. One side (4 terminals) is for
thermostat connections, the other side, pre-wired (5 terminals), is for the
control board connections.
