required.
i. Electronic Programmable Thermostat*:
Unit shall be capable of using deluxe full-featured
electronic thermostat. Thermostat shall use built-in
compressor cycle delay control for both heating and
cooling duty. Thermostat shall be capable of working
with Carrier direct digital controls.
j. Thermostat and Subbase*:
Thermostat shall provide staged cooling and heating
automatic (or manual) changeover, fan control, and
indicator light.
k. Outdoor Coil Hail Guard Assembly*:
Hail guard shall protect against damage from hail and
flying debris.
l. Unit-Mounted, Non-Fused Disconnect Switch:
Switch shall be factory-installed, internally mounted.
NEC and UL approved non-fused switch shall provide
unit power shutoff. Switch shall be accessible from
outside the unit and shall provide power off lockout
capability.
m. Convenience Outlet:
Switch shall be factory-installed and internally mounted
with easily accessible 115-v female receptacle. Switch
shall include 15 amp GFI receptacle with independent
fuse protection. Voltage required to operate convenience
outlet shall be provided by a factory-installed step-down
transformer. Switch shall be accessible from outside the
unit.
n. Outdoor Coil Grille:
The grille protects the outdoor coil from damage by large
objects without increasing unit clearances.
o. Compressor Cycle Delay:
Unit shall be prevented from restarting for minimum of
5 min. after shutdown.
p. Thru-the-Bottom Utility Connectors:
Kit shall provide connectors to permit electrical
connections to be brought to the unit through the basepan
q. Fan/Filter Status Switch:
Switch shall provide status of indoor (evaporator) fan
(ON/OFF) or filter (CLEAN/DIRTY). Status shall be
displayed over communication bus when used with direct
digital controls or with an indicator light at the thermostat.
r. Energy$Recycler:
The package shall be an outdoor rooftop or surface
mounted, electronically controlled, air-to-air heat pump
unit utilizing a hermetic compressor for cooling and
heating duty.
The Energy$Recycler shall recover energy from building
exhaust air and pre-condition ventilation air to allow
higher ventilation requirements and minimizing energy
cost.
This option shall be available with the following:
(1.) A mounting kit for the Energy$Recycler for
cantilever mounting off of the rooftop unit with out
the use of a slab or a roof curb.
(2.) A supplementary supply air fan kit to provide
increased air movement into the 62AQ unit.
(3.) A field-installed 460 v to 208/230 v transformer to
provide power when the Energy$Recycler is used
with a 460 v rooftop unit.
s. Power Exhaust Accessory for EconoMi$er IV or
EconoMi$er2:
P
ower exhaust shall be used in conjunction with
EconoMi$er IV or EconoMi$er2 to provide system exhaust
of up to 100% of return air (vertical only). The power
exhaust is a field-installed accessory (separate vertical and
horizontal design).
NOTE
: Horizontal power exhaust is intended to mount
in return ductwork.
As the outdoor-air damper opens and closes,
both
propeller fans are energized and de- energized through
the EconoMi$er IV controller. The set point is factory set
at 100% of outdoor-air, and is adjustable 0 to 100% to
meet
specific
job
requirements.
Available
in
208/230-1-60 v or 460-3-60 v. An LED light on the
controller indicates when the power exhaust is operating.
For the EconoMi$er2, the power exhaust shall be
controlled by the PremierLink or third party controls.
t. Outdoor Air Enthalpy Sensor (EconoMi$er IV or
EconoMi$er2):
The outdoor air enthalpy sensor shall be used with the
EconoMi$er IV or EconoMi$er2 device to provide single
enthalpy control. When used in conjunction with a return
air enthalpy sensor, the controller will provide differential
enthalpy control. The sensor allows the con-troller to
determine if outside air is suitable for free cooling.
u. Return Air Enthalpy Sensor (EconoMi$er IV or
EconoMi$er2):
The return air enthalpy sensor shall be used with the
EconoMi$er IV or EconoMi$er2 device. When used in
conjunction with an outdoor air enthalpy sensor, the
EconoMi$er IV or EconoMi$er2 device will provide
differential enthalpy control.
v. Return Air Temperature Sensor (EconoMi$er IV or
EconoMi$er2):
The return air temperature sensor shall be used with the
EconoMi$er IV or EconoMi$er2 device. When used in
conjunction with the standard outdoor air temperature
sensor, the EconoMi$er IV or EconoMi$er2 device will
provide differential temperature control.
w. Outdoor Air/Return Air Temperature Sensor (adjustable)
(EconoMi$er2):
Optional sensor uses the PremierLink control to control
outdoor air damper and compressor operation.
x. Indoor Air Quality (CO
2
) Sensor (EconoMi$er2):
(1.) Shall have the ability to provide demand ventilation
indoor air quality (IAQ) control through the
EconoMi$er2 with an IAQ sensor.
(2.) The IAQ sensor shall be available in duct mount, wall
mount, and wall mount with LED display. The set
point shall have adjustment capability.
(3.) Requires EconoMi$er2, PremierLink or Apollo
control options.
y. Indoor Air Quality (CO
2
) Room Sensor (EconoMi$er
IV):
Sensor shall have the ability to provide demand
ventilation control through the EconoMi$er IV. The IAQ
sensor shall be wall mounted with an LED display in parts
per million. The set point shall have adjustment
capability.
