INSTALLING OPTIONAL HH57LW001 SINGLE OUTSIDE
AIR ENTHALPY SENSOR
When using the HH57LW001 enthalpy sensor (see Fig. 77) for
outside air changeover, the existing HH79NZ039 dry bulb sen-
sor (see Fig. 78) must be removed. The enthalpy sensor will be
mounted in the same location as the dry bulb sensor (see
Fig. 79). When the enthalpy sensor’s OA (Outside Air) tem-
perature, enthalpy, and dew point are below their respective set
points, outside air can be used for free cooling. When any of
these are above their set point, free cooling will not be avail-
able. Enthalpy set points are configurable and create an enthal-
py boundary according to the user’s input. For additional de-
tails, see Fig. 80-81 and Table 22.
Harness 48TC005213 is required to be connected between the
EconomizerONE harness in the return air chamber. Harness
48TC005213 has a 5-pin plug that connects directly to the
HH57LW001 enthalpy sensor.
Enthalpy Control Sensor Configuration
The optional enthalpy control sensor (P/N: HH57LW001)
communicates with the POL224 economizer controller using
the 5-wire harness, 48TC005213. The HH57LW001 sensor can
be used as a single outside air enthalpy, a differential return en-
thalpy, or a differential return temperature sensor. Refer to the
base unit control wiring diagrams found earlier in this book to
wire the HH57LW001 enthalpy sensor for each option. See
Fig. 77 and Table 24 on page 60 to locate the wiring terminals
for each enthalpy control sensor.
