NOTE: If continuous backlight or

do not function in both HEAT and COOL
modes, cut the heating transformer 24V
wires and tape off. Connect the neutral
circuit disconnected from the heating
transformer to the neutral circuit of the
cooling transformer. Disconnect the wire
to the RH terminal and install a jumper
between RH and RC. Depending on
the system requirements, replace the
cooling transformer with a 75VA class II
120VAC
transformer if needed.
