ACCUSENSOR III
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 004-014 units. It then decides
when to energize the economizer based on this reading. The
016-028 unit economizer provides the decision-making function internally,
and requires one Accusensor III sensor for solid-state enthalpy sensing.
A second Accusensor III sensor (required for all units for differential
enthalpy sensing) compares outdoor temperature and humidity to returnair
temperature and humidity and determines the most economical mixture
of air (purchased in addition to enthalpy control [004-014] or to first
solid-state enthalpy sensor [016-028] for differential enthalpy sensing).
POWER EXHAUST (016-028 SHOWN)
When used with accessory/optional economizer, the power exhaust
accessory helps to relieve building over-pressurization.

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 (variable volume/variable temperature) system thermostats.
ELECTRONIC PROGRAMMABLE
THERMOSTAT
Carrier’s electronic programmable thermostat provides efficient temperature
control by allowing you to program heating and cooling setbacks
and setups with provisions for weekends and holidays. Accessory
remote sensing package is also available to provide tamperproof
control in high traffic spaces. Used in conjunction with factory-installed
Apollo control, this thermostat provides a 5-minute recycle timer between
modes of operation for short-cycle protection.
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.
