INTRODUCTION
These instructions describe the installation and adjust-
ment of the universal variable air volume (VAV) control pack-
age. This package contains all necessary control devices and
hardware for mounting the system-powered controls on 37HS1,
37HS2 and 37HS4 Moduline® units.
Note that for certain applications, additional control pack-
ages are required and must be ordered separately. These
include wall thermostats, warm-up valves, changeover valves
and electric warm-up valves. Separate installation instruc-
tions are provided in these packages.
This package supplements the individual VAV control pack-
ages offered for specific Moduline models. Table 1 shows
the control packages available for specific models and the
universal VAV package. Note that the constant volume con-
trol package applies to all 37HS models. Figure 1 shows the
contents of the universal VAV control package.
