with Two Transformers
NOTE: If continuous backlight or hard-
wired power input are desired but 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 trans-
former 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 trans-
former with a 75VA class II transformer if
needed.
