ECONOMIZER SYSTEMS
The 48TC units may be equipped with a factory--installed
or accessory (field--installed) economizer system. Two
types are available: with a logic control system
(EconoMi$er IV) and without a control system
(EconoMi$er2). See Fig. 81 and Fig. 82 for component
locations on each type. See Fig. 83 and Fig. 84 for
economizer section wiring diagrams.
Both economizers use direct--drive damper actuators.
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 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.

NOTES:
1. 620 ohm, 1 watt 5% resistor should be removed only when using differential
enthalpy or dry bulb.
2. If a separate field-supplied 24 v transformer is used for the IAQ sensor power
supply, it cannot have the secondary of the transformer grounded.
3. For field-installed remote minimum position POT, remove black wire jumper
between P and P1 and set control minimum position POT to the minimum
position.
