metal parts, and wires to replace the W7400 module and the
T7400 thermostats used in all Constant Volume 30-40 Ton

for all options including CV W/ Economizer, CV W/O Econo-
mizer, Optional Gas Heat, and Optional Electric Heat. Fig-
ures 1 and 2 illustrate the location of the Millennium controls
and the location of the W7400 in the control section. The
new low-voltage electric box will be as shown in Figure 4.
