General
This is a packaged electric element section, using finned rod elements, with a remote sensing control package
for modulating the electric elements.
The typical installation arrangement is shown in FIGURE 1.
The element power is standard 240-volt, single phase. Control is simply supplying the two control wires
with 24 volts to turn the unit on.
Caution:
The control contact mechanism for supplying 24 volts to the yellow and black wires must
have interlocking devices to assure airflow and the proper opening of any motorized dampers. This
unit depends upon an external blower or air moving device providing minimal airflow across the
electric elements before “turning the unit on”. Minimum airflow relates to temperature rise needs or
design, Table 2 – CFM Chart, provides these CFM numbers.
