Tab tlllla lb
6a 6b
Installation and servicing of air-condifioulng equipment can
be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should
install, repair, or service air-conditioning equipment.
Unlrgmed personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All other
operations should be performed by trained service personnel.
When working on aft-conditioning equipment, observe precautions in the litemtore, tags and labels attached to the unit, and
other safety precautions that apply.
Verify that the power source supplied to the unit matches
the voltages and amperages listed on the unit rating plate.
Follow all safety codes. Wear safety glasses and work
gloves. Use quenching cloth for unbrazing operations. Have
fire extinguishers available for all brazing opemtions.
Disconnect gas piping from unit when leak
testing at pressure greater than I/2 psig. Pressures greater than 1/2 psig will cause gas
valve damage resulting in hazardous condition. If gas valve is subjected to pressure
greater than V2 psig, it must be replaced
before use. When pressure testing fieldsupplied gas piping at pressures of U2psig or
less, a unit connected to such piping must be
isolated by manually closing the gas valve.
Before performing service or maintenance operations on
unit, turn off main power switch to unit and install a lockout tag. Electrical shock could cause personal injury.
GENERAL
Carrier's COBRA energy recovery units precondition ventilation air for the mot_op unit during winter and summer operation and recover energy from the building exhaust air. These
units are designed to satisfy the higher ventilation requirements
and other building codes while minimizing energy costs.
Factory installation of the 62AQ Energy$Recycler TM section provides the benefit of reduced field-installation time,
single point power connections, and the assurance of a factory
test for the complete COBRA energy recovery unit. The
Enetgy$Recycler section requires less maintenance than other
energy recovery systems and can be serviced by any qualified
refrigeration technician.
NOTE: The COBRA unit nameplate has been moved to the
opposite end of the rooftop
section, on the upper,
right-hand part of the panel due to the location of the 62AQ
Energy$Recycler section.
spedlica_ons or designs wib_out notice and without incurring obligations.

2. The flashing must be sealed to all ensure no water
can leak behind it, particularly around the 62AQ
Energy$Recycler TM section of the curb.
3. The Energy$Recycler section of the full-perimeter curb
must be watertight. See Fig. 2A and 2B.
Step I -- Inspect Shipment
--File
a claLm with the
sl_pping company if shipment is incomplete or damag_L See
Fig. 1 for typical shipping packaging of a COBRA TM energy
recovery unit.
Step 2 -- Provide
Unit Support -- The COBRA
energy recovery unit can use a full-perimeter roof curb or a
standard roof curb for the rooftop section of the unit with a supplemental equipment support for the energy recovery section.

COBRA UNIT WITH STANDARD ROOF CURB
If a
standard rooftop curb is used (for new or retrofit applications),
it is capable of supporting the rooftop unit section. An
accessory support rail must be used to support the 62AQ
EnergySRecycler TM section. Assemble end install accessory
roof curb in accordance with instmctious shipped with curb.
See Fig. 3A, 3B and 4. Install insulation, cant strips, roofing
felt, and counter flashing as shown.
Ductwork must be attached to curb, not to the unit. The accessory thru-the-bottom power and gas connection package
must be installed before the unit is set on the roof curb.
If the combined COBRA unit roof curb is not being used,
additional support is required under the EnergySRecycler
section of the unit. An accessory support and pad for the energy
recovery section or a field-fabricated and installed support can
be used. See Fig. 4. Place the protcctive rubber pad on the roof
so that the edge near the unit is located about 6 in. from the end
of the 62AQ EnergySRecycler sectiorl. Measure the distance
from the bottom of 62AQ Energy$Recycler rails to the pad.
Adjust the energy recovery equipment support to match the
measured distance and screw into place with the 4 screws
provided. See Fig. 4. Place the support underneath the
EnergySRecycler unit and on the protective rubber pad. This is
done by lifting the end of the 62AQ EnergySRecyeler section
slightly above level and then sliding the support underneath the
mils.
If electric control power or gas service is to be muted
through the basepan, a fteld-installed accessory thru-the-bottom

Curb should be level. This is necessary for unit condensate
drain to function properly. Refer to Roof Curb Accessory
Installation Insteactions for additional information as required.
Step 3 -- Field Fabricate
Ductwork
-- Secure all
ducts to roof curb and building structure. Do not connect ductwork to unit. Insulate and weatherproof all external ductwork,
joints, and roof openings with cotmter flashing and mastic in
accordance with applicable codes. See Fig. 5A and 513for duct
dimensions.
Ducts passing through an unconditioned space must be
insulated and covered with a vapor barrier. If a plenum return is
used, the return should be ducted through the roof deck to comply with applicable fire codes.
A minimum clearance is not required around ductwork.
These units are designed for a min'unum continuous healing
return-air temperature of 50 F (dry bulb), or an intermittent
operation down to 45 P (dry bulb), such as when used with a
night setback thermostat. To operate at lower r_urn-air temperatures, a field-supplied outdoor-air temperature control must be
used to initiate both stages of heat when the temperature is
below 45 K Indoor comfort may be compmmised when these
lower air temperatures are used with instdficient heating
temperature rise.

Step 4 -- Rig and Place Unit -- Keep unit upright
and do not drop. Spreader bars are not required if top crating is
left on unit. Rollers may be used to move unit across a roof.
Remove the bottom wooden skids that are under the unit by
removing the wooden plates that hold the bottom wooden
flame to the unit. Level by using unit frame as a reference. Lifthag holes are provided in base rails as shown in Fig. 6A and 613.
Refer to riggmg instructions on unit.
All panels must be in place when rigging.
POSITIONING
Maintain clearance around and above unit
to provide minimum distance fi'om combustible materials,
proper airflow, and service access. A properly positioned unit
will have the following clearances between unit and roof curb:
ll4-in,
clearance between roof curb and base mils on each side
and duct end of unit; i/4-in, clearance between roof curb
and condenser coil end of unit for size 004-007 units and a
3s/16-in. clearance between roof curb and condenser coil end of
unit for size 008-014 units.
Do not irtstall unit in an indoor location. Do not locate unit
air inlets near exhaust vents or other sources of contaminated
air.
Be sure that unit is installed such that snow will not block
the combustion intake or flue outlet.
Unit may be installed directly on wood floormg or on
Class A, B, or C roof_overing material when roof curb is used.
Although unit is weatherproof, guard against water from
higher level rtmoffend overhangs.
Flue vent discharge must have a minitman horizontal clearance of 4d from electric and gas meters, gas regulators, and
gas relief equipment.
Minimum distance between unit and other electrically live
parts is 48 inches.
Flue gas can deteriorate building materials. Orient unit
such that flue gas will not affect building materials. Locate
mechanical draft system flue assembly at least 48 in. from an
adjacent building or combustible material.
Adequate combustion-air and ventilation-air space must be
provided for proper operation of this equipment. Be sure that
installation complies with all local codes and Section 5.3, Air
for Comb_fion
and Ventilation, NFGC (National Fuel Gas
Code), and ANSI (American National Standards Institute)
Z223.1, and NFPA (National Fire Protection Association)
54 TIA-54-84-1. In Canada, installation must be in accordance
with the CAN1-BI49
installation codes for gas burning
appliances.
After unit is in position, remove rigging skids and shipping
materials.

Fig. 6A -- Rigging Label -- COBRA TM Energy Recovery Unit -- Sizes 48/50HJ004-007
this reason, the bottom drain on the rooftop unit CANNOT be
used for a condensate drain.
The 3/_-in.drain connection on the
energy recovery section is located near the bottom left of the
exhaust air section. See Fig. 5A and 513. The Energy$Recycler
section must have a field-fabricated, external, P-Irap installed for
condensate drainage. Trap must be at least 4 in. deep to protect
against freeze-up. If the drain line is installed downstream liom
the external trap, pitch the line away fi'om the unit at 1 in. per
10-fl of rim. Do not use a pipe smaller than the connection
Step 5 -- Install Flue Hood (48HJ Rooftop Sections Only) -- Refer to the 48HJ installation inslmctioas for
information on installing the flue hood.
Step 6 -- Install
Gas Piping (48HJ Rooftop Sections Only) -- The gas supply for gas heat units (48HJ) can
be ran through the curb or through the bottom of the unit. See
Fig. 7 and 8.
When installing the gas supply through the curb, the gas
piping will exit out through the side of the roof curb and a
hole in the base rail. The accessory thru-the-curb service
connections
(part numbers
CRBTMPWR001A01
and
CRBTMPWR002A01)
are required. See Fig. 9. A fieldsupplied regulator is installed outside the unit and the piping is
connected to the unit gas valve.
When installing gas supply through the bottom of the
unit, the gas piping is routed through a knockout in the unit
basepan and then connected to the unit gas valve. The
accessory thin-the-bottom service connections (part numbers
CRBTMPWR003A01
and CRBTMPWR004A01)
are require& See Fig. 10 and 11. Refer to the 48HJ installation
instructions for more information on installing the gas piping.
Step 8 -- Make Electrical Connections
Unit cabinet must have an uninterrupted, unbroken electrical ground to minimize the possthility of personal injury if
an elcclrical fault should occur. This ground may consist of
electrical wire connected to unit ground lug in control compartment, or conduit approved for electrical ground when
installed in accordance with NEC (National Electrical
Code), ANSI/NFPA, latest edition, and local electrical
codes. Do not use gas piping as an electrical ground Failure to follow this warning could result m the installer being
liable for personal injury of others.
Step 7 -- Install External Trap For Condensate
Drain -- The condensate from the rooftop unit along with
condensate from the upper coil of the 62AQ Energy$Recycler TM
section is internally piped to the condensate pan in the lower
section of the 62AQ Energy$Recyeler section. See Fig. 12. For
FIELD POWER SUPPLY -- All units except 208/230-v
units are factory-wired for the voltage shown on the nameplate.

Gas Connections
When installing units, provide a disconnect per the NEC.
All field wiring must comply with NEC and local
requirements.
Install field wiring as follows:
1. Install conduit through side panel openings. Install conduit between disconnect and control box.
2. Install power lines to terminal connections as shown in
Fig. 13-15.
GAS
SERVICE
PLATE
Voltage to compressor terminals during operation must be
within voltage range indicated on unit nameplate
(see
Tables IA-1H). On 3-phase units, voltages between phases must
be balanced within 2% and the current within 10%. Use the formula shown in the legend for Tables 1A-1H, Note 2 to determine the percent of voltage imbalance. Operation on improper
line voltage or excessive phase imbalance constitutes abuse and
may cause damage to electrical components. Such operation
would invalidate any applicable Cartier warranty.
FACTORY-SUPPLIED NON-FUSED DISCONNECT
The
factory-supplied disconnect is capable of handling disconnect
amps up to 80 A for a COBRA energy recovery unit. For disconnect amps greater than 80 A, a field-supplied disconnect is
required.
Fig. 9 -- Thru-the-Curb
Gas Connection (Accessory)
FIELD-CONTROLWlRING
There are three required
inputs to properly control COBRA TM units: temperature,
humidity and an occupied/unoccupied
schedule. The four recommended control combinations are:
•
•
EMBOSSMENT
BRASS
ThermidistatrM and electro_mechanical controls (Fig. 16)
digital thermostat, humidistat and electro-mechanical controis (Fig. 17)
• humidistat, space temperature sensor and PremierLink TM
controls (Fig. 18)
• Thermidistat and PremierLink controls (Fig. 19)
The most widely used combinations are the light commercial
Thermidistat or PremierLink with thermostat and humidistat.
SUPPORT
BRACKET
FITTING
Fig, 10 -- Internal Gas Line Piping with Thru-theBottom Connection (3 to 6 Ton Shown)
If the unit is equipped with the Humidi-MiZer TM or
MoistureMi$er TM option, these systems also require a humidity
input. The Energy$Recycler wiring accepts the sensed space

THERM1DISTAT
DEVICEThe light commercial Thermidistat device is a 7-day programmable, wall-mounted, low
voltage field-installed control. It combines temperature and
humidity control in a single unit and provides separate set
points for heating and cooling. The control adds a dehumidification control function with separate set points for up to 2
occupied and unoccupied periods per day.
Ifa Thermidistat device is used, install the Therraidistat assembly accessory according to installation instructions included with the accessory. Place the Thermidistat assembly on a
solid wall in the conditioned space to sense average temperature in accordance with Thermidistat installation instruction on
page 43. Connect Thermidistat wires to terminal board. Route
Thermidistat cable or equivalent single leads of colored wire
fi'om subbase terminals through connector on unit to lowvoltage connections (shown in Fig. 16). Thermidistat control
wiring is routed to both the rooftop unit control box and the
62AQ Energy$Reeycler control box.

PREM1ERLINK TM CONTROLLER -- The PremierLink digihal controller is a Direct Digital Control (DDC) box that mounts
in the motIop unit under the main unit control box. It is
designed to be connected to the Carrier Comfort Network®
(CCN) system, where all the input and output points and control screens can be monitored for servicing and troubleshooting
purposes. However, the PremierLink controller can also be
connected and operated via thermostat. For details and additional information, refer to the Retrofit PremierLink Installation
Instructions and Application Data.
The PremierLink controller is available factory-installed or
as a field retrofit accessory. The PremierLink controller is
designed to allow users the access and ability to change factory
defined settings, thus expanding the function of the standard
rooftop unit control. However, the PremierLink controller does
not have an incorporated visual interface. It requires a
CCN accessory such as a Navigator TM device, System PilotTM
unit or personal computer equipped with Carrier's proprietary
ComfortWORKS® or ServiceTool software.
20 mA humidity signal from the humidity sensor. The universal
controller provides an output relay contact that is connected to
the HM terminal in the Energy$Recycler section's cuntml box.
The humidity sensor output does not connect directly to the
COBRA unit. The universal controller is used to configure the
humidity sensor's set point; when the sensed humidity level is
reached, the controller sends a signal to the HM terminal.
The universal controller is also connected to the CCN bus
wiring, therefore the humidity set point and sensed humidity
value is displayed on the network. One universal controller can
be used for up to eight (8) different COBRA units.
The PremierLink controller has two modes of sensor input:
Temperature mode or Sensor mode. In Temperature mode, the
PremierLink controller accepts input from a Carrier approved
space thermostat. Input connections for this mode use terminal
strip TB3 as shown in Fig. 21-23. Terminal strip TB3 connects
to the J4 contacts on the PremierLink module. When the
PremierLink controller is factory-installed, it is completely
wired, except for the field-installed sensors. Currently, the only
sensor that is included from the factory is the supply air temperature sensor. The following field-installed sensors are
required for PremierLink controller operation:
If a PremierLink controller is used, a Thermidistat device
does not have to be used; a harnidistat and separate room air
sensor can also be used. Two extra terminal blocks (TB2 and
TB3) are provided in the control box for all units with PremierLink controls. No wires should be directly connected to the
PremierLink control. Wire sensors to "1332or TB3. Humidistat
is wired to TB 1 and the Energy$Recycler section. See Fig. 17.
•
•
Pass the control wires through the hole provided in the comer
post; then feed wires through the raceway build into the comer
post to the 24-v barrier located on.the left side of the control box.
See Fig. 20A and 20B. The raceway provides the UL required
clearance between high voltage and low voltage wiring.
The PremierLink controller does not support humidity control. A separate field-supplied humidity device that supports contact closure must be used. However, remote humidity sensing
and control on a CCN system is possible using a PremierLink
controller, a 3V rM universal controller and a 3V compatible
humidity sensor. In this configuration, the universal controller
provides 24 vdc power to the humidity sensor and accepts a 4 to

1. In compliance with NEC requirements for multimctor and combination load equipment (refer to NEC Articles 430 and 440)), the
overcurrent protective device for the unit shall be fuse or HACR
breaker. UL, Canada units may be fuse or circuit breaker.
2. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is greater than 2%, Use the following formula to determine
the percent of voltage imbalance.
= 1.53%
This amount of phase imbalance is satisfactory as it is below the

INDOOR AIR QUALITY AND CO2 SENSORS -- If a space
CO2 sensor is desired, a field-installed 25% outdoor-air damper
must be used for proper Demand Control Ventilation (DCV)
operation. If not, the 62AQ Energy$Recycler unit outdoor-ak
dampers will remain shut unless the space CO2 levels are
above the CO2 set point.
The 25% outdoor-air damper should be placed in the normal location on the base rooftop unit. See Fig. 24. This damper
will allow additional outdoor air to be brought in if the CO2
level is high, independent of 62AQ unit operation. In the
occupied mode, the 62AQ unit will usually bring in enough
fresh air to maintain CO2 levels below the set point. If not, the
25% outdoor-air damper will open to allow additional fresh air
to be brought in. See Fig. 25 and 26 for control wiring. The recommended CO2 sensor is a 33ZCSENCO2 and the recommended 25% outdoor-air damper is a CRTWOPOSOOIA01 or
a CRTWOPOS002A01
(dependent on rooftop unit size). See
33ZCSENC02 or 25% outdoor-air damper installation instructions for additional information.
4. From the outside of the unit's side panels fasten the
thermostat(s) with two mounting screws, with the quick
connect terminals face up. See Fig. 27.
5. Install thermostat knobs (provided in kit). See Fig. 27.
6. Set supply air unant__ (on units with optional factory÷
installed supply air fan [GA] or field-installed accessory
supply air fan kit [CRFANKIT001-006A00]).
Select the
fan speed and damper position to obtain desired cfm.
Relocate damper stops to the desired position on the
damper support rail and adjust the fan speed by relocating
the wire on the supply fan motor terminal block. Factory
set position is 45 degrees for the damper position, and
medium speed for the motor. Relocate stops to top hole
for 30 degrees, bottom hole for 60 degrees, and remove
stops for 90 degrees (see Fig. 27).
7. Install the aluminum filter screen and end cap with
screws along the top, as shown in Fig. 27.

Step 11 -- Set the Outdoor
ing Thermostats
Cooling and Heat-
• On a sectinn of wall without pipes or ductwork.
The light commercial Thermidistat device should NOT be
motmted:
• Close to a window, on an outside wall, or next to a door
leading to the outside.
• Exposed to direct light and heat from a lamp, sun, fireplace, or other temperature-radiating
object that may
cause a false reading.
• Close to or in direct airflow from supply registers and
return-air registers.
• In areas with poor air circulation, such as behind a door
or in an alcove.
IMPORTANT: The 62AQ Energy$Recycler TM section is
shipped with an outdoor thermostat set at 55 F which locks
out mechanical cooling on the rooftop section and the
Energy$Recycler section compressor. If this feature is not
desirable, the rooftop unit's compressor can be allowed to
run by relocating both gray wires to the same side of the low
temperature lockout thermostat (LTLO) leaving the white
wire on the opposite pole, locking out only the
Energy$Recycler
section compressor. The LTLO is also
accessible by removing the filter access panel and the door
of the damper mounting bracket.
F
COOLING -- During the unoccupied period, the economizer
mode of operation is used as the first stage of cooling. When
the outside air temperature is below the cooling thermostat set
point, the outside air will be used for first stage cooling.
HEATING
The heating thermostat should be adjusted to the
second stage balance point (heat output of the energy recovery
section plus the heat output of the ftrst stage on rooflop unit
equals building load at this temperature). Above this setting,
first stage heating will be the energy recovery section unit and
second stage will be the ftrst stage of the rooftop unit. Below
this point, first stage heating will be the Energy$Recycler
section plus first stage heating of the rooftop unit. The second
stage will be the second stage of the rooftop unit.

The light commercial Thermidistat is a 7-day programmable, wall-mounted, low-voltage control that combines temperature and humidity control in a single unit. It provides separate
set points for heating and cooling, and adds dehumidification
with separate set points for occupied and unoccupied periods.
Different heating and cooling set points and times are
programmable for up to 4 periods per day and 7 days per week.
The dehumidification
output provides direct control of the
EoergySReeycler section, rooftop section fans, and the rooftop
section compressor in response to the programmed time schedules and temperature settings. During power loss an internal
memory stores programs and settings for unlimited time, and
the clock continues to run for at least 8 hours. Batteries are not
used.

more secure mounting if needed. Make sure all wires
extend through hole in mounting base.
6. Adjust length and routing of each ware to reach proper
connector block and terminal on mounting base with
t/4-in, extra length. Strip only I/n in. of insulation from
each wire to prevent adjacent wires from shorting together when connected.
7. Match and connect equipment wires to proper terminals
of each connector block. Remember R and C must be
connected for proper operation (see Fig. 30).
SWITCH 3 -- SMART/CONVENTIONAL
RECOVERY -Switch 3 selects between conventional or smart recovery from
setback. Conventional recovery changes to new set point at

OPtion 14 -- Heat/Cool Deac!lpand Adjustment -- This option selects the minimum difference between heating and cooling set points. A larger difference saves energy and a smaller
difference decreases temperature difference between heating
and cooling. Factory default is 2, which means cooling set
point must be a minimum of 2 degrees above heating set point.
An attempt to move them closer will result in one "pushing"
the other to maintain the required difference.
Depending on set points, moving deadband closer than
2 degrees may result in regular cycling between heat and cool
when AUTO mode is selected. However, this cycling cannot
occur more often than 1 transition every 10 minutes. The system has a built-in requirement that it cannot switch between
heat and cool without a 10-miunte "off' time between the 2
operations. Specifically, to switch from one mode to the other,
there must be no demand for the old mode and a demand for
the new mode, and this must exist continually for 10 minutes
before transition to the new mode will occur.

Option 13Room Temperature Offset Adjust -- This option allows calibration (or deliberate miscalibration) of room
temperature sensor. There are various reasons why building
owners may want to have displayed temperature adjusted to a
higher or lower value. The selected number is number of
degrees, plus or minus, which will be added to actual
temperature. The numbers can range between -5 and +5.
Factory default is 0. This adjusted value will be used as actual
temperature for both display and con_ol action. For example, if
2 is selected, 72 F actual will read 74 F. lfset point is 72 F, the
room will control to an actual temperature of 70 F which will
be displayed and acted upon as if it were 72 E The effect is that
a positive number selection will make the room temperature
lower and vice versa. The light commercial Thermidistat
device is calibrated within an accuracy of± 1o F when shipped
fix_m the factory, so this adjustment will provide the best
accuracy when set to 0.

them to change with pregrammed schedule.
During unoccupied periods the FAN button may be used to
select between AUTO (fan on only with equipment) and FAN
(fan on continuously) fen modes. During occupied periods the
fan is on continuously.
DEHUMIDIFICATION--Dehumidification
is done only
during cooling. A dehumidification set point is available to the
owner in both occupied and unoccupied times. It can range from
50 to 90% relative humidity. When actual humidity is higher
then set point, a dehumidification demand exists. In the occupied period, the light commercial Thermidistat TM device
responds by activating its dehumidify output (DEHUM) turning
on the compres.sor in the energy recovery section; and when
a call for cooling exists, energizing the Humidi-MiZer TM
solenoid in the 48/50HJ unit (if so equipped). The 62AQ
Energy$Recycler TM compressor will be started in the Occupied
mode even though a call for cooling does not exist; thus dehumidifying the outside air before it enters the building. In the
unoccupied period the humidistat will only energize the
Humidi-MiZer solenoid in the main unit.
dependent on the occupied signal.
Fan button switches FAN icon between AUTO and ON.
While ON is displayed, G output will be on, turning fan on.
Allow up to 10 seconds after button is pressed for fen to tau'non
and off. On 3 through 121/2 ton energy recovery units, the fan
continues to operate for a minimum of 30 seconds after G
signal is removed.
NOTE: In other than the Installer Test mode the fan will run
continuously during the occupied periods. If auto fan is
selected, the fan will come on with a heating or cooling call
during the unoccupied periods and run continuously during the
occupied periods. The fan icon AUTO will be lit if auto fan is
selected and ON will be lit when the fan is on.
TO TEST COOLING
AND DEHUMIDIFICATION:
Press MODE button until COOL icon toms on. YI cooling
begins within 10 seconds and remains on for 4 minutes. Two
minutes after Y1 comes on, the Y2 signal is energized for
2 minutes. At the end of 4-minute ran, cooling stops and
MODE reverts to OFF. At any time during 4-minute run time,
cooling may be turned off by pressing MODE button until
OFF appears. While cooling is on, successive presses of
HUMIDITY button turns the dehumidify output on and off.
While this output is active, the "DFMUM" icon will be
energized.
TO TEST PRIMARY HEATING:
However, if the humidity is below the set point in the
unoccupied period, a "mini" economizer mode will be initiated,
bringing in outside air to cool the space as the first stage
of cooling, provided the outdoor air thermostat in the energy
recovery section is below its set point.
HOLIDAY -- A holiday selection is available specifically for
times where the building will not be occupied for an extended
period. For convenience, one button selects Holiday mode
which is indicated by "HOLIDAY" icon on LED display. Holiday mode also has an automatic hold, meaning that set points
are not affected by the programmed schedule. While in Holiday mode, the system provides temperature and humidity protection for the building in all seasons, but not comfort.
Holiday Set Points -- The settings for HEAT, COOL, and
DEHUM should have been done in the Configuration mode
(Options 9,10, and 1I).
Press MODE button until HEAT icon toms on. WI heating
begins within I0 seconds and remains on for 4 minutes. This
is the Recycling mode. If the outdoor temperature is below the
balance point it will also include first stage furnace or electric
heat in AC system. W1 will be on for 2 minutes followed by
second stage W2 for 2 minutes. If the outdoor temperature is
above the balance point, this second stage call will energize
first stage furnace or electric heat in AC system. If the outdoor
temperature is below the balance point, this second stage call
will energize second stage furnace or electric heat in AC
system. At the end of 4-minute ran, heating stops, and MODE
reverts back to OFF. At any time during 4-minute run time,
heating may be turned off by pressing MODE button until
OFF appears. While heating is on, successive presses of
HUMIDITY button turn Occupied output on and off. While
this output is active, "OC" appears in cool set point display.
OPERATIONAL
There are two different controls available: a light commercial
Thermidistat device or a Humidstat in conjunction with a temperature
sensor,
The light commercial Thcmlidistat device is a 7-day programmable, wall mounted, low voltage field-instaned control.
It combines temperature and humidity control in a single unit
and provides separate set points fur heating and cooling. The
control adds a dehumidification control function with separate
set points for up to 2 occupied and unoccupied periods per day.
Step 6 p
Make Final Settings -- Be sure to return
DIP switch no. 4 back to OFF position to exit Installer Test
mode. Assuming the system is to be left in operation after
installation is complete, use MODE button to select between
HEAT, COOL, or AUTO to provide desired operation of heating, cooling, or both.
The default set points and programmed

INFORMATION
Different heating and cooling set points and times are programmable for up to 4 periods per day 7 days per week. In case
of a power loss an internal memory stores programs and settings for unlimited time, and the dock continues to run for at
least 8 hours. Batteries are not used.
The light commercial Thermidistat device (or Humidistat
and temperature sensor) provides direct control of the energy
recovery section, rooftop unit fans, and rooftop unit compressor
in response to the programmed time schedules and temperature
settings. The dehumidification output signal controls the energy
recovery compressor to cool and dehumidify the supply air via
a relay.
Typical unit airflow is shown in Fig. 33. See Table 2A end
2B for operating information and system response.

on the temperature and humidity requirements as sensed in
the space. Either a Carrier Thermidistat TM device (combined
temperature and humidity sensing capability) or separate
thermostat and humidistat can be used with the Httmidi-MiZer
system. See Tables 3A and 3B for sequence of operation of
COBRA units equipped with the Humidi-MiZer dehumidification option.
Unoccupied
Cooling Mode -- During unoccupied
periods the system fans and compressionwill cycle in response
to the light commercial Thermidistat device's (or Humidistat
and temperature sensor) temperature and humidity output signals to maintain space conditions at programmed set points.
During mild weather, if the outdoor temperature is below the
outside-air thermostat (OAT) set point, all compressor operation is locked off and the s_,stem operates in the economizer
mode to provide flee cooling.
Healing with H_midi-MiZer in Unoccunied Mode -- In the
unoccupied mode, the Energy$Recycler (E$R) unit is off and
all compressors are locked off. First stage heat is rooftop section heat at 50%. Second stage heat is rooftop unit heat at
100%. See Table 3A.
If outdoor air is unsuitable (humidity or air quality), then the
Energy$Recycler TM section will be off. If outdoor air is suitable, then both the EnergySRecycler section and the rooftop
section will be used for cooling. First stage of cooling is the
Energy$Recycler section in economizer mode. Second stage
of cooling energizes the Energy$Recycler
and rooftop
compressors.
Headng with Humidi-MiZer in Occunied Mode -- In the occupied mode, when the ESR compressor runs in heat mode, it
extracts heat from the exhaust air and rejects heat to the incoming outdoor air, returning energy to the building that, otherwise,
would be wasted. The E$R and rooftop section fans run continuously. Rooftop section compressors are always off.
On a first stage call, the ESR compressor is on in heat mode.
If the outdoor air is above the set point, rooftop section heat is
off. Rooftop section beat is on at 50°/0 iftbe outdoor air is below the set point. On a second stage call, the E$R compressor
is on in heat mode. Rooftop section heat is on at 50% if the outdoor air is above the set point. Rooftop section heat is on at
100% if the outdoor air is below the set point. See Table 3B.
Occupied
Cooling
Mode -- During occupied periods,
the Energy$Recycler fans and the rooftop unit's fans run continuously to maintain proper airflow and ventilation rotes. The
compressors in the Energy$Recycler section and the rooftop
unit cycle in response to the dehumidification and thermostat
output signals from the control to maintain proper tempemtore
and humidity levels.
Cooling Operation with the Humidi-MiZer
TM
Option (Units after October 2004) -- Units equipped
NOTE: If there is a thermostat call from the space for heating,

mode) will not operate.
with the Humidi-MiZer dehumidification option are capable of
increased humidity control by utilizing a common subcooling/
reheat dehumidification coil. This unique and innovative design
provides the capability of the rooftop section to operate in both a
subeooling mode and a hot gas reheat (HGRH) mode. A
48/50HJ rooftop unit equipped with the Humidi-MiZer system
can be used with or without a 62AQ EnergySRecycler TM unit.
See the Humidi-MiZer Application Data manual for additional
details.
MOISTUREMI$ER TM OPTION (Units prior to October
2004) -- Units equipped with the MoistureMiSer dehumidification option have an up to 40% increase in latent capacity in
hot, humid climates. The MoistureMi$er dehumidification
option increases humidity control and comfort in the occupied
space by automatically lowering the evaporator coil temperatore to optimum dehumidification levels while simultaneously
reheating the leaving air to prevent overcooling.
The
MoistureMi$er capabilities have been incorporated into the
Humidi-MiZer system; the MoistureMi$er is no longer an
available option for units produced after October 2004.
The incorporation of the Humidi-MiZer adaptive dehumidification system on a COBRA TM unit adds significant flexibility to the overall system. The response of the Humidi-MiZer
system to varying space conditions is extremely dynamic. The
COBRA energy recovery unit or 48/50HJ rooftop unit
equipped with the Humidi-MiZer system will respond based
