ZONE THERMOSTAT CONTROL RELAYS — A unique
feature of the Aquazone system control panel is the capability to
add zone ther mostat contr ol rela ys. T his feat ure is used w hen th e
Aquazone system control panel i s utilized in a st and-alone type
of installation. Eithe r a set of 10 or 18 relays can be selected
from the 50RLP model nomenclat ure in digi t 9 to control ei the r
10 or 18 zones, respectively. If selected in the model nomencl a­ture, zone control relays are located on the right hand side of the
system control panel. See Fig. 4. See Fig. 5A-5C for wiring.

CONTROL TRANSFORMERS — Control transformers are
supplied with the Aquazone system control panel and are wired
to the power switch and convenience outlet. The control
transformers provide power to the nominal 24 VAC circuit in
Aquazone system control panel. The contractor will supply the

primary power to the power switch and conve nience outlet in
the field. Transformers include a manual reset button for reset­ting the circuit breaker. Control transformers are located on the
bottom half of the system control panel. Specifications for the
control transformers are as follows:

Primary: 120/208/240 vac
Secondary: 24 vac
Frequency: 60 Hz

MOUNTING RAILS AND WIRING DUCT — All exposed
panel wiring is low voltage. Line voltage wiring to the control
transformers, control circuits for pumps, cooling tower fans,
and boilers is factory-installed in conduit, using wiring duct,
and on mounting rails.

POWER RECEPTACLE — A power receptacle is provided
in the Aquazone™ system control panel and is located in the
bottom left corner. Specifications for the power receptacle are
as follows:

Power: 120 vac
Rating: 15A @ 120 vac for receptacles

15A @ 120 vac for switch
250 V for fuse

WATER TEMPERATURE SENSORS — Two water tem­perature sensors and thermowells have been provided with the
Aquazone system control panel. The first sensor is utilized to
read loop supply water temperature, such that the system
control panel can adjust heat rejection and heat addition
equipment to maintain the loop temperature based on user
input. The second sensor may be installed to monitor return
loop water temperature. The active sensing element is a highly
stable precision thermistor material accurate to within ± 0.36 F.
The temperature range of the sensor is 10 F to 230 F.

WATER PRESSURE SENSOR — A water pressure sensor is
provided with the Aquazone system control panel with variable
speed pumping only , and is utilized to operate variable frequen­cy drives for system pumps. The water sensor senses system
pressure and the pressure is sent to the system control panel.
The Aquazone system control panel speeds up or slows down
the variable frequency drive to control the pump in order to
keep the system at the correct pressure.

When a variable frequency drive is used for system pump­ing, the Aquazone water source heat pumps are typically
furnished with a factory or field-mounted solenoid valve that
allows water to flow though the heat pump. When solenoid
valves open, the system pressure drops, which results in the
variable frequency drive speeding up to allow the pump to

provide more water. When solenoid valves close, the system
pressure rises, which results in the variable frequency drive
slowing down to allow the pump to provide less water.

WATER FLOW SWITCH — A factory-provided wat er flow
switch is included with the Aquazone system control panel and
must be field-installed in the water loop piping. The flow
switch is connected to the control panel by a cable with a
watertight connector. This device uses a triac output that cannot
be connected directly to the Main Base Board. Therefore, a
control relay is used to signal the Main Base Board that loop
water flow is detected. The switch contains a fifteen-turn
adjustment potentiometer, to be used to adjust the set point in a
range of 3 to 60 cm/sec. The factory set point is 20 cm/sec.

The potentiometer switch may be adjusted down to zero
velocity (no flow) or above 60 cm/sec, however operation
in those ranges may not be linear or reliable.

Install Thermostat, Sensors and Switches —

In
all installations, the loop supply water temperature sensor and
water flow switch must be installed in the field. The water
pressure sensor is used to sense water system pressure to
operate in conjunction with pump variable frequency drives.
A thermostat is used in stand-alone systems. A space tempera­ture sensor is used in conjunction with water source heat
pumps provided with PremierLink™ controllers. Refer to the
accessory installation instructions literature provided with each
accessory that is used for accessory installation instructions.

NOTE: All thermostats, sensors, and switches are field­installed accessories.

Install Loop Water Supply and Return Tem­perature Sensors —

sor in the main water supply, located before the water source
heat pumps. Install the water loop return sensor in the return
water piping from the water source heat pumps. The sensors
must be inserted fully into an immersion well ( provided). Seal
immersion well threads with tape and install into pipe tee or re­ducing fitting. The well screws into a
Thredolet fitting) furnished by the installing contractor. Screw
the sensor into the well via the
nate wiring with butt splice or soldering. Wire nuts are not rec­ommended. Use full 8 ft of lead length provided to avoid mois­ture migration up the wire. Wire the supply sensor to terminals
SSWT. Wire the return sensor to terminals SRWT. See Fig. 8.
Sensors may be located in any position in relationship to the
main supply line. Use shield cable to protect from any electri­cal interference.

Install Loop Water Pressure Sensor —

pressure sensor on the discharge side of the circulating pump(s)
in a common supply main so that total system pressure rather
than individual pump(s) flow is detected. The pr essure sensor
must be placed in a vertical position and must match the actual
water flow direction with flow switch direction indicators. Seal
the switch fitting with Teflon tape and insert in a

standard pipe tee (Thredolet fitting) or reducing fitting, with at
least three pipe diameters straight run upstream and down­stream of the switch. Wire sensor to terminals SDP. See Fig. 8.

Install Loop Water Flow Switch —

Install the loop
water flow switch on the discharge side of the circulating
pump(s) in a common supply main so that total system flow
rather than individual pump(s) flow is detected. The flow
switch must be placed in a vertical position and must match the
actual water flow direction with flow switches direction indica­tors. Seal the switch fitting with Teflon tape and insert in a stan­dard pipe tee or reducing fitting, with at least three pipe diame­ters straight run upstream and downstream of the switch.

Electrical connection can be made to the switc h. Two wires
should be run to the switch for 24 VAC power. The switch is
supplied with wire leads for connection to the FLOW terminal.
When power is supplied to the device, a warm-up period is
initiated. During this period, the right green LED will be lit.
Each LED to the left is successively lit until the farthest left red
LED is lit. Each LED will be turned off when the next is lit.
The warm-up period may take up to 30 seconds.

When flow is detected, a red LED at the far left will be lit.
With increasing flow, successive red LEDs will be lit. When
the switch determines sufficient flow is present, the amber
LED lights indicating the output has closed. This is not an indi­cation of minimum flow. As flow increases, the first green
LED will be lit. Each successive green LED indicates greater
flow. The switch closure does not indicate minimum flow for
the machine. With one green LED lit, minor fluctuations in
water flow may cause nuisance alarms. Additional green LEDs
indicate higher flow rates, and can avoid the nuisance alarms.
The switch is calibrated to light the amber LED at a fluid
velocity of 0.8 ft/sec (0.24 m/sec). The flow rate will depend on
the nozzle size. See Table 4. See Table 5 for Water Flow
Switch Troubleshooting. If the water flow switch is not work­ing correctly, refer to Table 5.

PROBLEM SOLUTION

No display or output from the flow sensor

Flow sensor indicates zero flow
when flow is present

Flow Sensor indicates flow
when no flow is present

Check for 24 VAC across pins 1 and 3. These are small pins and caution should
be used when measuring the voltage in the harness so as not to damage the connector.

Check flow switch pin connections for damage.
Check for air in the chilled water system.
Check for 24 vac across pins 1 and 3. These are small pins and caution should be used

when measuring the voltage in the harness so as not to damage the connector.
Check for fouling on the sensor switch, which could inhibit the dissipation of heat from the probe.
Consider replacing the flow switch. The switch might be out of calibration,

the internal heater may have been damaged by extreme temperatures, pressure
or vibration, or mechanical damage to the tip of the device may have occurred.

Check for 24 vac across pins 1 and 3. These are small pins and caution should
be used when measuring the voltage in the harness so as not to damage the connector.
Low voltage can lead to less heat generated by the internal heater.

Consider replacing the flow switch. The switch might be out of calibration, the internal
heater may have been damaged by extreme temperatures, pressure or vibration, or
mechanical damage to the tip of the device may have occurred.

Connect to CCN Communication Bus —

The
Aquazone™ system control panel primary controller connects
to the bus in a daisy chain arrangement. Negative pins on each
component must be connected to respective negative pins and
likewise positive pins on each component must be connected to
respective positive pins. The controller signal pins must be
wired to the signal ground pins. Wiring connections for CCN
must be made at the 3-pi n pl ug. See Fig . 9.

At any baud (9600, 19200, 38400 baud), the number of
controllers is limited to 239 devices maximum. Bus length may
not exceed 4000 ft, with no more than 60 total devices on any
1000-ft section. Optically isolated RS-485 repeaters are
required every 1000 ft.

NOTE: Carrier device default is 9600 baud.
COMMUNICATION BUS WIRE SPECIFICATIONS —

The CCN Communication Bus wiring is field-supplied and
field-installed. It consists of shielded three-conductor cable
with drain (ground) wire. The cable selected must be identical
to the CCN Communication Bus wire used for the entire
network. See Table 6 for recommended cable.

NOTE: Conductors and drain wire must be at least 20 AW G
(American Wire Gage), stranded, and tinned copper. Individual
conductors must be insulated with PVC, PVC/nylon, vinyl,
Teflon, or polyethylene. An aluminum/polyester 100% foil
shield and an outer jacket of PVC, PVC/nylon, chrome vinyl,
or Teflon with a minimum operating temperature range of
–20 C to 60 C is required.

The communication bus shields must be tied together at
each system element. If the communication bus is entirely
within one building, the resulting continuous shield must be
connected to ground at only one single point. If the communi­cation bus cable exits from one building and enters another
building, the shields must be connected to the grounds at a
lightning suppressor in each building (one point only).

LID Operation —

CCN operator interface that gives the user the capability to
view and modify all configuration and service data for the
Aquazone System Control Panel Controller. The LID also
gives the user the capability to override all point display and
maintenance data.

MENU STRUCTURE — The LID operates on a hierarchy of
four levels (menus).

The top level contains the LID’s major functions. Each
function has a corresponding key on the LID. For an explana­tion of each function key, refer to Table 7.

The second level separates the major functions (items) into
types with corresponding type numbers that can be used for
quick access.

The third level gives the user the capability t o access each
occurrence of an item. For example, the application may
require two DO — Analog Comparison algorithms. Thus, the
Aquazone System Control Panel Controller would have two
occurrences of the DO — Analog Comparison algorithm.

The fourth level gives the user the capability to access main­tenance and configuration data associated with the selected
occurrence of the item.

Sequence of Operation

HEAT RE JECTIO N — When the system pumps are operat ­ing and there is flow to the system, heat rejection control
compares the system supply water temperature to the hi gh set
point in the system loop temperature set points.

If the system supply water temperature approaches the high
set point, the controller commands the heat rejection outputs to
hold the system supply water temperature as close as possible
to the high set point.

If the system return water temperature drops below the
system high water temperature set point minus a hysteresis
value the heat rejection, outputs are disabled.

When the cooling tower output control type is set to
“variable,” the heat rejection outputs are calculated using a PID
calculation based on the system high temperature water set
point. Both outputs will modulate together.

When the heat rejection control type is set to “staged,” the
outputs will be modulated in a lead/lag configuration. The
modulating signal of the lead output will control a transducer
of two or four stages.

When the lead output is at 100% and the set point is not
being maintained, the lag output will be modulated to produc e
staging from another two or four stage output transducer.

The value output by each analog output is determined by a
PID calculation of leaving water temperature versus the system
high leaving water temperature set point.

In the event that the system high water temperature set point
cannot be maintained and is exceeded by a defined Hysteresis,
the heat rejection outputs will go to maximum output, the
system water source heat pumps will stop cooling, and the
system pumps will circulate water until the system tempera­tures are returned to the normal range. System cooling will
then be allowed to continue.

HEAT ADDITI ON — When the system pumps are operating
and there is flow to the system, boiler control compares the
system supply water temperature to the low set point in t he
system loop temperature set points.

If the system supply water temperature approaches the low
set point, then the controller commands the boile r outputs to
hold the system supply water temperature as close as possible
to the low set point .

If the system return water temperature rises above the
system low water temperature set point plus a Hysteresis value,
the boiler outputs are disabled.

When the boiler output control type is “variable,” the boiler
outputs will be calculated using a PID calculation based on the
system low temperature water set point. Both outputs will
modulate together.

When the boiler control type is set to “staged,” the outputs
are modulated in a lead lag configuration. The modulating
signal of the lead output controls a transducer (two or four
stages).

When the lead output is at 100% and the set point is not
being maintained, the lag output modulates to produce staging
from another two or four stage output transducer.

The value output by each analog output i s determined by a
PID calculation of leaving water temperature versus the system
low leaving wa ter temp eratu re se t poi nt.

In the event that the system low water temperature set point
cannot be maintained and is exceeded by a defined Hysteresis,
the boiler outputs will go to maximum output, the system water
source heat pumps will stop heating, and the system pumps
will circulate water until the system temperatures are returned
to the normal range. System heating will then be allowed to
continue.

WATER CIR CULATION — When operational mode is de­termined by one of the 18 occupancy schedules, one of the 18
network or global schedules, or occupancy overrides, then the
system pumps are put in operational mode. Also, if one of t he
system enable outputs is forced on, then the system pumps are
put in operational mode.

If the remote occupancy input is detected, then the pumps
are put in operational mode and all 18 schedules overridden to
on. This energizes all 18 system enable outputs.

The pump control type is configured as either variable flow
or constant flow . When the pumps are in operational mode, the
pump speed output values are determined in one of two ways:

1. In constant flow mode, the desired output (one or two) is
ramped to 100% to turn the pumps on in a lead/lag
fashion, based on run time.

2. In variable flow mode, both outputs are determined by a
Proportional Integral Derivative (PID) calculation, which
controls the system pressure set point.

Whenever the runtime of the lead pump exceeds the
runtime of the lag pump by 50 hours or more, then the pump
with the lesser runtime will become the lead pump.

If the lead pump output is at 100% and the loop water flow
input detects no flow, then the lag pump will be put to 100% to
start the lag pump. Both outputs will stay at 100% as an indica­tor that the lead pump did not start.

At each subsequent start-up, the lead pump will be tried
again. If both pumps are commanded to 100% and no flow is
detected, then the pumps will be forced off. To restart the sys­tem, a pump must be energized manually or the flow switch
must be overridden to indicate flow. The lead pump will start if
there is a demand for system circulation.

In the event that the pumps have been commanded to
provide water flow but either the flow switch does not indicate
flow or the differential pressure sensor does not indicate pres­sure is present, then the controller assumes that the pumps have
failed and commands the water source heat pumps to turn off
cooling or heat. The system fans will continue to circulate the
air.

In the event of a system shutdown command, the controller
commands the water source heat pumps to turn off all cooling
and heat sources and circulating fans.

CONFIGURATION

The Aquazone™ System Control Panel contains a Comfort
Controller 6400 programmed using the standard algorithms
and enhanced by BEST++™ custom programming. The
BEST++ Templates for some of the programs have been
removed to prevent field alterations. For other programs,
the templates are included to allow for jobsite customization.
For basic information about the algorithms please refer to the
Comfort Controller Overview and Configuration manual
(808-891). Default configurations are listed later in this section.

OUTSIDE AIR TEMPERATURE — This software point is
included to receive an Outside Air Broadcast. If the system
is set up with Outside Air Broadcast, a control force will
be displayed on the OAT point of all system controllers.
For systems with factory-installed PremierLink™ controllers,
the individual unit leaving water temperature sensors are
connected to the OAT point. When OAT broadcast is enabled,
the leaving water temperature sensors connected to the
PremierLink controllers may be displayed temporarily by
removing the Outside Air Broadcast force. The Outside Air
Broadcast will be refreshed the next time the outside-air

LEAD PUMP CONSTANT FLOW — When the Aquazone
system control panel is configured for constant flow, this point
displays the current lead pump. This point may be forced to
keep the lead pump the same for more than the maximum
hours difference required for pump rotation. When the pump
runtime hours difference becomes greater than the maximum
number configured the pump runtime hours for both pumps
will reset to zero.

For example, the default maximum hours difference for
rotation is 50 hours. If the Lead Pump was forced to 2, so that
pump 2 is the lead pump, then the pump 2 runtime hours will
accumulate until the difference between the pump 1 and pump
2 runtime hours becomes greater than 50. The both will reset to
zero and pump 2 will start accumulating again.

GLOBAL SCHEDULE BROADCAST — If des i red, the
schedules 1 through 18 in the Aquazone™ system control
panel may be reconfigured to be schedules 65 through 82 (so
that they may be used as global schedules). If this is done, this
configuration must be set to 1. Local inputs for overriding
zones 1 to 18 or the remote occupancy input will then affect the
global schedules 65 through 82. In this condition local override
of individual PremierLink™ controllers will not occur since
the comfort controller does not respond to the command from
any PremierLink controller to override a global schedule. It is
recommended to allow the PremierLink controllers to broad­cast global schedules.

25

The loop controller comes pre-configured with local schedules
1 through 18. It is also pre-configured with network schedules 65
through 82 in order to receive global schedules broadcast from
PremierLink™ controllers or other networked controllers. See
Network Time Schedule section. This is the recommended
method for using global schedu les since a PremierLink controller
(when set up to broadcast a global schedule) will respond to a
schedule override request from another PremierLink controller
that it is broadcasting the global schedule. This allows all
PremierLink controllers following the same global schedule to
enter occupancy override as a group.

MANUAL OVERRIDE HOURS — The Manual Override
Hours point is used to command a timed override by entering
the number of hours the override will be in effect. If the occu­pancy schedule is occupied when this number is downloaded,
the current occupancy period will be extended by the num ber
of hours downloaded.

If the current occupancy period is unoccupied when the
occupancy override is initiated, the mode w ill change to oc cu­pied for the duration of the number of hours downloaded. If the
occupancy override is due to end after the start of the next
occupancy period, the mode will transition from occupancy
override to occupied without becoming unoccupied and the
occupancy override timer will be reset.

An active occupancy override or a pending occupancy
override may be canceled by downloading a zero to this
configuration. Once a number other than zero has been down­loaded to this configuration, any subsequent downloads of any
value other than zero will be ignored by the controller.

OCCUPANCY SCHEDULE — For flexibility of scheduling,
the occupancy programming is broken into eight separate peri­ods. For each period the schedule contains the following fields:
Day of W eek, Occupied From, and Occupied T o.

DAY OF WEEK — The Day of Week configuration consists
of eight fields corresponding to the seven days of the week and
a holiday field in the following order: Monday, Tuesday,
W ednesday, Thursday, Friday, Saturday, Sunday, Holiday.

It is displayed as:

M T W Th Fr Sa Su Hol
0 0 0 0 0 0 0 0

If a 1 is configured in the corresponding place for a certain
day of the week, the related “Occupied from” and “O ccupied
to” times for that period will take effect on that day of the
week. If a 1 is placed in the holiday field, the related times will
take effect on a day configured as a holiday. A zero means the
schedule period will not apply to that day.

Network Time Schedule —

The network time schedule
allows the occupancy schedule in another device on the CCN
to control the Aquazone™ system control panel’s occupancy
state.

Each time the occupancy schedule on the controlling device
changes to occupied, the controlling device broadcasts an
occupancy flag over the CCN. To receive an occupancy flag,
a network time created. Up to 18 network time schedules are
configured. The schedules are sequentially named OCCPC65E
to OCCPC82E, however Service Tool or Building Supervisor
software can be used to modify the names up to OCCPC99E.

Holiday Schedules —

A Holiday schedule allows the
user the capability to specify days of the year (holidays) on
which the Aquazone system control panel will follow the
holiday time schedule instead of the normal time schedule for
that day. Holiday time schedules are normally used to program
a weekday in unoccupied mode for the entire day since the
building will be empty during a holiday.

There are 16 different holiday schedules that can be created.
Holiday schedules can also last more than one day, as long as
the days are consecutive.

Holiday schedules must be configured on the time and date
broadcaster element on the CCN. If the Comfort Controller on
the Aquazone system control panel is the broadcaster, it will
send holiday status to all other system elements on the CCN. If
the Comfort Controller is not the broadcaster, do not configure
the holiday schedules for it, as they will not be used.

To configure a holiday schedule, ente r a “1” i n th e Holiday
column of the Day of Week point of the Occupancy schedule.
