Taco Comfort Solutions VR15 User manual

1. GENERAL INFORMATION, USES:
The circulating pumps are used for the transfer of liquid media
within a closed-looped hot-water heating or air-conditioning
hydronic system. They are designed as single or parallel
main/standby operation variable-speed pumps, where the speed
is regulated by an on-board electronic device. They are to be used
with a water or glycol/water mixture.
2. SAFETY:
These instructions should be studied carefully before installing or
operating the pump. They are meant to help you with installation,
use and maintenance and to increase your safety. Installation
should be performed with regards to local or national standards.
Only qualified personnel should maintain and service these prod-
ucts. Failure to comply with safety precautions could cause per-
sonal injury or machinery damage.
3. PUMP DESCRIPTION:
The high efficiency, electronically commutated 00e pumps consist
of two main parts, the centrifugal pump and the electronic regulator.
The hydraulic part is hermetically sealed from the motor assembly
and has no mechanical seals. 00e pumps are powered by an ECM
permanent magnet motor which does not consume energy to mag-
netize the rotor, providing superior energy efficiency.
The ECM motor is run by an on-board frequency converter with an
integrated PFC (Power Factor Correction) filter. The converter
estimates current flow and head from the motor load, information
essential for differential pressure control.
4. PUMP INSTALLATION:
The 00e™ pump is protected with a double box during shipping. It
can be lifted from the box with internal handles or by lifting it by the
heat sink.
Pumps are designed to be installed using standard ANSI class
125 flanges. It is recommended that the 00e pumps be installed
with at least 5 to 10 pipe diameters of straight pipe on the inlet and
outlet of the pump. Use all nuts and bolts to attach companion
flanges to the pump flanges. For pumps to operate with minimal
vibration and noise, it should be installed with the axis in a hori-
zontal position (see Figure 1).
esired head orientation can be achieved by rotating the pump
head. The pump is mounted to the volute with four screws. By
unscrewing those the head can be turned. Caution: When
reassembling, care should be taken to avoid damaging the O-
ring and insuring a tight seal. For replacement O-rings, use part
number 975-001RP. See detailed Motor Rotation Procedure 4.1
below.

4.1 Motor Rotation Procedure
Caution: Motor is heavy!
1. If possible, change the orientation of the motor before
installing pump in piping. With motor in a vertical position,
remove the 4 bolts (5⁄16” or 8mm hex wrench required) and turn
the motor to agree with desired orientation of pump (see
Figure 1). If motor won’t turn, insert a screwdriver between
pump casing and motor flange and raise slightly. Try turning
motor. Insert screwdriver on opposite side, raise slightly, and
try turning the motor. Motor should now turn - now line up bolt
holes when desired orientation is achieved.
2. Caution: If system is filled and pressurized, shut off valve
before and after the 00e. Allow to cool if system fluid is hot.
3. If the pump is already installed in the piping, remove the 4
bolts (5⁄16” or 8mm hex wrench required) and try rotating the
motor without backing it out from the pump casing. Try crack-
ing the motor approximately .020” using a screwdriver
between the motor and pump housing and try turning the
motor.
4. If motor will not move, remove motor completely.
5. Remove impeller, rotor, and rotor can from the motor. Note:
Rotor and impeller assembly will come out first. Remove rotor
can from motor and put aside.
6. Install impeller and rotor assembly into pump.
7. While holding rotor, install O-ring in casing, and then slide rotor
can over rotor and slide all the way in.
8. Rotor and rotor can should stay in place while you pick up the
motor. If they do not, start over to assure O-ring is properly
located and have someone hold the assembly in place with a
screwdriver on top of the plate.
9. Pick up the motor with the terminals properly orientated and
carefully start to slide the motor over the rotor can. The resis-
tance of the sliding will keep the rotor and rotor can assembly
in place and the screwdriver can be moved. Note: Do not
allow the motor to droop or the O-ring might get out of
position.
10. Line up the bolt holes, reinstall the bolts, and tighten in a
cross-pattern.
11. Carefully open shut off valves and check for leaks.
Make sure that the electrical box cover is mounted and that all
cable glands are installed to prevent dust and particles from cont-
aminating the electrical box.
4.2 Electrical Connections:
NOTE: For 200 to 240/1/60 volt, L1 and L2 are connected to L and
N in the electrical box.

The pump has built-in over current fuse protection, temperature
protection and basic overvoltage protection. It does not require
additional overload protection devices unless required by local
electrical codes. Power supply cabling should be capable of carry-
ing rated power and be properly fused. Ground lead connection is
essential for safety and should be connected first. Grounding is
only meant for pump safety. System piping should be grounded
separately. A ferrite core is supplied in a separate bag. Electronic
cabling and wires, by virtue of their length-to-width ratios, are per-
fect natural antennas. The ground, line and neutral power supply
wires should go through the ferrite core to help reduce unwanted
high-frequency interfering signals. The pump should not be oper-
ated without the electrical cover securely attached.
4.3 Relay Connections:
The pump is supplied with normally open, normally closed and
common relay connections. See Section 9.2 Electrical Data for
specifications. These can be used to activate or deactivate a pri-
mary or secondary pump or alarm contact, actuate a damper for
combustion air or switch another piece of equipment. Factory
default is activation of relay on fault. Additional relay “triggers” are
standby, I2 activation and run digital input commands.
4.4 Digital Inputs:
The pump can be switched between standby mode or maximum
power via the digital inputs.
4.4.1 Pump External Control Wiring Diagrams:
The following diagrams are examples of external control wiring to
digital inputs I1 and I2.
4.4.2 External Control Settings:
On/Off/Standby/Max speed external control variances and subse-
quent effects are listed in the chart below. Refer to Section 6.5
Pump Settings to modify digital input and relay settings from fac-
tory defaults.
4.5 Constant 24 Volt DC Power Supply:
There is a constant, unswitched 24Vdc/100mA output power supply
across terminals 24V/0V. This power is interrupted only if the main
power supply to the 00e is turned off.
5. REGULATION MODES:
Pump defaults to provide 23 feet (7m) of head with variable differ-
ential pressure (∆p-v) regulation. If the factory settings are not
suitable they can be modified over an Ethernet connector or a web
interface. Various regulation parameters (constant head, supply
power, rpm limit) can adjust the head and flow characteristics until
the pump achieves desired response to suit the application.
5.1 Constant Pressure Control (∆p -c):
Electronic regulation can provide
constant head by modifying power
input and is set with the Limit
head (Hmax) setting. The duty
point of the pump will move left
and right along a constant-pres-
sure curve based upon the water
demand in the system. The pump
head (pressure) is kept constant,
irrespective of the water demand.
Hmax proportional to Q needs to
be set to 0% (see Section 6
Connection to a Network -
Pump Setup).
Selecting the constant pressure regulation is beneficial when the
00e is installed in a system where there is a much lower resistance
(friction loss) in the main distribution loop compared to the resis-
tance in the transfer part of the system (i.e. baseboard radiation,
radiant floors, terminal units). For example, this characteristic of
generally lower head loss can be found in converted gravity sys-
tems, systems operating with large temperature spreads or where
the pump is moving the total volume of flow through the boiler and
distribution lines.
5.2 Variable Differential
Pressure Control (∆p -v)
- Factory Default Setting:
Additional energy savings and
noise reduction is achieved with
proportional head regulation that
also compensates for changes in
system friction losses during peri-
ods of changing flow rates. In this
mode the pump head changes
continuously as the demand for
water changes, reducing as the
water demand declines and
increasing as the water demand rises.
The Hmax proportional to Q setting provides a user adjustable
curve slope. An Hmax proportional to Q of 0% means that the
head does not exhibit any dependence to flow and should not
exhibit noticeable change until maximum power is reached. An
Hmax proportional to Q set to 60% means that the pressure will
drop for 60% from set value when there is no flow. For example if
the head is set to 20', the pump will only provide 12' when the
valves are closed and the pump is dead headed (operating at zero
flow). The factory default is 23' at 50%. Note, a substantial per-
centage of glycol in the mixture can influence regulation.
Select the variable differential pressure control when the 00e is
installed in a system where there is a much higher resistance (fric-
tion loss) in the main distribution loop compared to the resistance
in the transfer part of the system (i.e. baseboard radiation, radiant
floors, terminal units). For example, this characteristic of the prima-
ry circuit having a high pressure drop can be seen in systems using
modulating condensing boilers or heat exchanges, heavily throttled
branch shut-off valves, where the distribution lines are long or in
two pipe systems with thermostatic or zone valves.
FACTORY DEFAULT FUNCTION
I1 (IO1/0V)
Normally open or 2Vdc and less, pump runs normally.
Closing contact (or applying 8Vdc or above) sets the
pump to standby mode by disabling power to the motor
(eg: for Warm Weather Shut own). Additional I1 input
signals are maximum power (speed) and no effect.
I2 (IO2/24V)
Closing I2 or 8Vdc and above (only when I1 is closed)
forces the pump to run at Max (eg: purge system of air
on start-up). Has no effect if I1 is open. Additional I2 input
signals are run and no function.

5.3 Constant Duty Curve
(Unregulated Pump)
Control:
An unregulated pump
decreases its head with
increasing flow. This unreg-
ulated setting can be
achieved by setting the limit
head (Hmax) to “no limit
(99)” in the pump tab (see
below) with a jumper across
IO2/24V (or 8Vdc and
above). Note: I1 must be
closed and set to "no function". Limit rpm to should be set to the
maximum value to achieve full pump curve. This allows the pump to
run just like a conventional
non-variable speed pump.
5.4 RPM Regulation:
Provides regulation similar
to a manually adjustable
pump.
5.5 Power Limitation:
Artificially limits power con-
sumption and output by
selecting a maximum amp
draw.
6. CONNECTION TO A NETWORK - PUMP SETUP:
In order to change the factory default operating parameters of the
pump or to use various web tools the pump needs to be connected
to a network or a personal computer over the Ethernet plug. Use
CAT-4 or better network cable connected to “PATCH” configuration
if plugged into a network or connect an Ethernet cable directly
between a PC and the 00e.
To achieve pump IP protection, network cable should be fed
through the glanded inlet and then crimped to a connector.
Ethernet plug is galvanically insulated, but the rest of the cabling
could still present shock hazard.
If more than one pump will be connected into network, each indi-
vidual pump should have its IP address and NetBIOS name
changed and noted. That will prevent network confusion and pro-
vide naming service in relation to pump function.
6.1 Web Interface Settings:
When the 00e is connected to a network or another computer, it
can be reached by typing its IP address or NetBIOS name into the
internet explorer’s address line. The default IP address is
192.168.0.245 and default NetBIOS name is “00e”. The pump can
be switched between standby mode or maximum power via the
digital inputs.
6.2 Setting Up the Default IP Address:
Once the Ethernet cable is connected between the 00e pump and
either the laptop or network, go to your Control Panel and select
Network Connections. Right click on Local Area Connection and
choose properties. Highlight Internet Protocol Version 4
(TCP/IPv4) then click on properties. In the TCP/IP address use the
following IP address “192.168.0.XXX” (example 192.168.0.123).
Click OK to finish.
CAUTION: All connections should be made with
the power to the pump turned off.
ATTENTION: Tous les raccordements doivent être
effectués avec l'alimentation électrique vers la
pompe coupée.

Prior to connecting the pumps via the Ethernet Crossover cable,
program each pump’s “Pump IP address” and “Twin mode with IP”
addresses. See 9.1 and 9.2 below.
NOTE: It is highly recommended that if the pump IP address
(and/or the Net BIOS name) is modified from factory default set-
ings then these changes are recorded and the change is posted
on the pump itself.
Reprogramming the pumps needs to be completed to each pump
individually prior to connecting the pumps together. See Section 6,
Subsection 6.6 Network Settings. A standard Ethernet or Ethernet
Crossover cable can be used to reprogram each pump.
Once completed:
• One pump will run and show a blue light.
• The second pump will be on standby mode indicated by a
flashing blue light (drive is enabled and the motor is disabled).
• An automatic alternation between the two pumps will occur
every 24 run-hours. This is not adjustable and is a factory
default.
To confirm communication between the pumps once reprogramming
is complete and the Ethernet Crossover is connected:
• Observe the blue power lights on the face of the drives. One is
on constantly and the other pulses.
• Observe the two communication lights at the RJ-45 Ethernet
connection in each pump’s terminal box. Both pumps should
have one LE on continually with the second LE pulsing
(indicating intercommunication).
• To confirm communication, turn off the main power supply to
the running pump. After 10 to 15 seconds, the second pump
will switch from standby to on (flashing blue light changes to
solid blue and the motor starts).
• Once communication is confirmed, turn on the power prior to
leaving the job site. This pump will now be in standby mode
(flashing blue light).
Notes:
Both pumps should be the same size and “Head Max” and
“Proportional %” set to the same value. See Section 6, Subsection
6.5 Pump Settings.
This is main/standby operation only. Both pumps will not run at the
same time as long as the Ethernet Crossover cable is connected.

10. 00E WIRELESS ROUTER SETTINGS:
The following are instructions to set up an external wireless router to
communicate with a 00e Pump.
Follow the instructions that came with the router to perform modifica-
tions required in LAN settings and wireless settings.
Shown here is the Netgear WN R3700, but many routers have sim-
ilar interfaces. Note that this will NOT provide internet service to
your laptop or mobile device NOR will it make the 00e accessi-
ble over the internet.
10.1 Wireless Setting:
This is where it is possible to personalize the name of the wireless
network. The example below illustrates a network called “00e
Wireless”. Regardless of the wireless network name, once set-up,
the wireless device (iPhone, iPad, PC, Mac or Android device) is
directed to connect to that network (“00e Wireless” as an exam-
ple).

IP address
is a pump network address. The pump is seen as http server on this address.
Subnet mask
sets subnet address range that is on the same subnet and can be reached
directly. The rest of communication goes over the gateway.
Default gateway
provides connection route to larger networks. This is usually a router
address.
NetBIOS name
is a local network name server. Instead of '192.168.0.245' you can for
example use 'http://00e'.
Twin mode IP
will connect two pumps for alternating operation. When two pumps are
configured for twin mode, they will switch about once per day. Setting this
field to unexistent IP will disable this option. Set it so the first pump
references the second and vice versa.
(!)Use 'Save' carefully. Incorrect settings might render pump unreachable. If
you change the IP address, you will need to manually enter it into browser
window.

10.2 LAN (Local Area Network) Setting:
The factory default IP Address of the 00e is 192.168.0.245. It is not
necessary to change this unless multiple 00es are connected to
the same router. See Notes below.
Set Router LAN TCP/IP as follows:
• IP Address 192.168.0.1
• IP Subnet mask 255.255.255.0
Set Router HCP as follows:
• Check “Use Router as HCP Server” box
• Starting IP Address 192.168.0.2
• Ending IP Address 192.168.0.100
10.3 Steps to Communicate with the 00e After Changes are
Complete:
Plug in an Ethernet cable to the device input at the back of the
router (not the Internet or “WAN” input) and to the Ethernet con-
nection at the 00e.
Power up all devices (the 00e can be forced into standby by plac-
ing a jumper across I01 and 0V digital input to eliminate dry oper-
ation of the rotating assembly).
Connect to the wireless network with the iPhone (or other wireless
device), using the network name set in the “Wireless Setting” section.
Open up the device web software (Safari, Windows Explorer,
Firefox etc.).
Open the website “00e” or enter the pump’s IP Address
192.168.0.245 in the address window, click enter.
Connection is complete and status or adjustments to the 00e can
be made.
Notes:
Multiple 00es can be plugged into the router, although each pump
would require a different IP address and name.
No other changes to the router are required from factory settings.
