ACCUSENSOR™ II
CONTROL
ACCUSENSOR III
SENSOR
Accusensor economizer controls help provide efficient, economical
economizer operation. Accusensor II solid-state enthalpy control
includes the logic and one sensor to calculate both dry- and wet-
bulb of the outdoor air to provide an accurate enthalpy reading on. It
then decides when to energize the economizer based on this read-
ing. A second Accusensor III sensor compares outdoor temperature
and humidity to return-air temperature and humidity and determines
the most economical mixture of air (purchased in addition to first
solid-state enthalpy sensor for differential enthalpy sensing).
ECONOMI$ER
Electric heaters are available in a wide range
of capacities for factory or field installation.
FACTORY-INSTALLED APOLLO
COMMUNICATING CONTROLS
The Apollo direct digital controls are designed exclusively by
Carrier, and are used to actively monitor and control all modes of
operation as well as to monitor evaporator-fan status, filter status,
supply-air temperature, outdoor-air temperature, and indoor-air
quality. They are designed to work in conjunction with Carrier
TEMP and VVT® system thermostats.
ELECTRIC HEATER
Factory-installed EconoMi$er utilizes a microprocessor-based con-
trol, gear drive damper system, low pressure drop characteristics,
built-in spring return (for close upon power loss), and an integral
barometric damper.
NOTE: EconoMi$er is only available for vertical ductwork applica-
tions and can be field or factory installed.
