OUTDOOR AIR ENTHALPY CONTROL —
(PN: 33CSENTHSW) —
The enthalpy control is available as a
field-installed accessory to be used with the EconoMi$er
®
2 damp-
er system. The outdoor air enthalpy sensor is part of the enthalpy
control. (The separate field-installed accessory return air enthalpy
sensor (33CSENTSEN) is required for differential enthalpy con-
Locate the enthalpy control in the economizer next to the Actu-
ator Motor. Locate two GRA leads in the factory harness and con-
nect the gray lead labeled “ESL” to the terminal labeled “LOW”.
See Fig. 88. Connect the enthalpy control power input terminals to
economizer actuator power leads RED (connect to 24V) and BLK
(connect to GND).
Fig. 88 — Enthalpy Switch (33CSENTHSW) Connections
The outdoor enthalpy changeover setpoint is set at the enthalpy
controller.
Differential Enthalpy Control — Enthalpy control is provided by
sensing and comparing the outside air and return air enthalpy con-
ditions. Install the outdoor air enthalpy control as described above.
Add and install a return air enthalpy sensor.
Return Air Enthalpy Sensor (33SENTSEN) — The sensor is
mounted in the return-air section of the economizer. The return air
sensor is wired to the enthalpy controller (33CSENTHSW). See
Fig. 89 — Outside and Return Air Enthalpy Sensor Wiring
SMOKE DETECTORS —
Smoke detectors are available as
factory-installed options on 580J models. Smoke detectors may be
specified for Supply Air only or for Return Air without or with
economizer or in combination of Supply Air and Return Air. All
components necessary for operation are factory-provided and
mounted. The unit is factory-configured for immediate smoke de-
tector shutdown operation; additional wiring or modifications to
unit terminal board may be necessary to complete the unit and
smoke detector configuration to meet project requirements.
Units equipped with factory-optional Return Air smoke detec-
tors require a relocation of the sensor module at unit installation.
See Fig. 90 for the as shipped location.
