DURABLADE ECONOMIZER
Exclusive Durablade economizer damper design saves
energy while providing economical and reliable cooling. A
sliding plate on the face of the economizer controls the
amount of outdoor air entering the system. When the sliding
plate is closed, it provides a leakproof seal which prevents
ambient air from seeping in or conditioned air from seeping
out. It can be easily adjusted for 100% outdoor air or any pro-
portions of mixed air. Equipped with standard controls and
30% barometric relief capabilities.
THERMOSTAT
Zone thermostat (24 v) provides one- or 2-stage
cooling for control of unit. Matching subbases are
available with or without tamperproof switches
and automatic changeover.
HUMIDISTAT
ACCUSENSOR™ II ENTHALPY CONTROL
Field-installed, wall-mounted humidistat is used to control
operation of the MoistureMiser dehumidification package. The
humid-istat controls the occupied space humidity at a user-
selected setting between 20% and 80% relative humidity.
ACCUSENSOR III
DIFFERENTIAL
ENTHALPY
Accusensor economizer controls help provide efficient, economical
economizer operation. The Accusensor I dry-bulb sensor measures out-
door temperature and is standard with the Durablade economizer.
The accessory Accusensor II solid-state enthalpy control senses both
dry and wet bulb of the outdoor air to provide an accurate enthalpy read-
ing. Accusensor II is available as a field-installed accessory for the Dura-
blade economizer.
The accessory Accusensor III differential enthalpy sensor control com-
pares outdoor temperature and humidity to return-air temperature and
humidity and determines the most economical mixture of air. Accusensor
III is available for the Durablade economizer only.
APOLLO DIRECT DIGITAL CONTROLS
Apollo direct digital controls are designed exclusively by Carrier,
and are used to actively monitor all modes of operation as well as
evaporator-fan status, filter status, indoor-air quality, supply-air tem-
perature, and outdoor-air temperature. They are designed to work
with Carrier TEMP and VVT® system thermostats.
