TE: If  continuous backlight or hardwired
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 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
transformer if  needed.
