:::::     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.
