Installing Accessory Connections
The HE 1.5 Controller enclosure has several portals to allow connections to HE accessories. Each connection portal is
molded into the controller enclosure. If the portal is not already opened and/or plugged, it may be opened by pushing a
sharp object (screwdriver or knife) through the plastic. See Figure 21.
A connector/bushing and/or plug should be placed in the port assigned for each HE 1.5 accessory. See Figure 21 and
Figure 22 and Table 6 for connector/bushing and plug types and their position on the HE 1.5 Controller enclosure.
