IMPORTANT: Any economizer that meets the econo -
mizer requirements as laid out in California’s Title 24
mandatory section 120.2 (fault detection and diagnostics)
and/or prescriptive section 140.4 (life-cycle tests, damper
leakage, 5 year warranty, sensor accuracy, etc), will have
a label on the economizer. Any economizer without this
label does not meet California’s Title 24. The five year
limited parts warranty referred to in section 140.4 only
applies to factory installed economizers. Please refer to
your economizer on your unit.
IMPORTANT: The optional EconoMi$er
®
2 does not
include a controller. The EconoMi$er2 is operated by a 4 to
20 mA signal from an existing field-supplied controller. See
Fig. 62 for wiring information.
