Economi$Er Systems - Carrier WeatherMaster Puron 48HC D17 Service And Maintenance Instructions

ECONOMI$ER SYSTEMS

IMPORTANT: Any economizer that meets the economizer
requirements as laid out in California's Title 24 mandatory
section 120.2 (fault detection and diagnostics) and/or pre-
scriptive 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 fac-
tory-installed economizers. Please refer to the economizer
on the unit.
The 48HC units may be equipped with a factory-installed or
accessory (field-installed) EconoMi$er system. Three types are
available: with a logic control system (EconoMi$er IV and
EconoMi$er X) and without a control system (EconoMi$er2).
See Fig. 54-56 for component locations on each type. The
W7212 controller is used for EconoMi$er IV and the W7220
controller is used for EconoMi$er X. See Fig. 57-60 for
EconoMi$er section wiring diagrams.
All three EconoMi$ers use direct-drive damper actuators.
