PUMP DESCRIPTION: The high efficiency, electronically commutated 00e VR15 - 30 model pumps consist of two main parts,the centrifugal pump and the electronic control.The hydraulic part is hermetically sealed from the motor assembly and has no mechanical seals. 00e pumps are powered by an electronically commutated permanent magnet motor(ECM) which does not consume energy to magnetize the rotor, providing superior energy efficiency. The ECM motor is run by an on-board frequency converter.The converter estimates current flow and head from the motor load, information essential for differential pressure control. 6. USE: All Taco 00e VR pumps are intended for circulation of solid-free fluid in pressurized, hot and chilled hydronic systems. The self-sensing ECM pump constantly calculates pressure and flow, and adapts its speed to the appropriate flow. 7. PUMPED FLUIDS: Use water and water/glycol mixtures only. Water/glycol mixtures must be HVAC-system compatible and should have no more than 50% concentration of glycol. The fluid shall not consist of aggressive or explosive additives and mixtures of mineral oils and solid or fibrous particles. The pump should not be used for pumping flammable, explosive fluids, and in an explosive environment. 8. PUMP INSTALLATION: The 00e(R) 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. ACAUTION: Pump may be heavy. Provide yourself help if needed. ATTENTION: La pompe est lourde.Veillez a deman-der de I'aide si necessaire. 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. All VR model pumps should be installed with the axis in a horizontal position (see Figure 1). Failure to so may result in excessive noise and vibration. Desired pump orientation can be achieved by rotating the pump casing. The pump is mounted to the volute with four screws. By unscrewing those the head can be turned. See detailed Motor Rotation Procedure 8.1 elovy. Caution: When reassembling, care should be taken to avoid damaging the o-ring and insuring a tight seal Figure 1: RECOMMENDED INSTALLATION POSITIONS N;ALL!t t7v���� � 411P.M[E1 pa% ' e, _ UNAUTHORIZED INSTALLATION POSITIONS 1-`' i111111111111111 .�t �J���t•I.r Iill•t•t•t•lr 1M1111 111I111 •����' 1 ri!

Caution: If system is filled and pressurized, shut off valve before and after the OOe.Allow to cool if system fluid is hot. 8.1.1. Notice! It is recommended to always change the orientation of the motor before installing pump in piping. • Tools Required: 1 • 5/16" or 8mm ball-end hex wrench • '/4"or 3/8"flat tip screw driver ;. ,• • With motor in a vertical position, remove the 4 bolts (ill.1) • Using a flat tip screw driver, gently pry the motor and housing away from the pump housing ill. 1 • Once loosened, lift the motor off the pump housing, leaving behind the rotor/shaft assembly and seal. (ill. 2) 11 ,i • The motor is now ready to be rotated into the desired position. ! - • Before reinstalling the motor, check to make sure that the rotor/shaft is properly ► , seated and the seal is properly positioned. (ill. 3) - II The flange of the rotor/shaft assembly must fit into the shallow groove (ill. 4) in the pump housing with the 0-ring accessible without removing the rotor/ ill. 2 shaft assembly. illjrit • If you determine that the assembly has moved, completely remove the 0-ring and the rotor/shaft assembly. • Reinstall the rotor/shaft assembly into the shallow groove and place the 0-ring seal in position as shown. (ill. 3) Spin the rotor, it should turn freely. • Turn the motor so the control box is in the desired orientation. Lift the motor, line up ill.3 the bolt holes and gently slip the motor over the rotor/shaft assembly being sure that the motor and rotor/shaft assembly are aligned. Once aligned the motor housing face will make contact with the pump housing face. NOTE: • Clearances between the pump housing and the motor housing are very tight. To ensure proper fit it is important to gently manuver the motor housing into the casing. DO NOT use force to insert the 4 motor housing into the pump housing! ' 7- • Insert the bolts and tighten in a cross pattern. \ \ _ ill.4 • Install into piping and skip to 8.1.3 ,` ,.a. !� r1 02/07/26019 ASPEN BUILDING DEPARTMENT 8.1.2 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 cracking the motor approximately .020" using a screwdriver between the motor and pump housing and try turning the motor. • If motor will not move, remove motor completely. 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. • Install impeller and rotor assembly into pump. • While holding rotor, install 0-ring in casing, and then slide rotor can over rotor and slide all the way in. • Rotor and rotor can should stay in place while you pick up the motor. If they do not, start over to assure 0-ring is properly located and have someone hold the assembly in place with a screwdriver on top of the plate. • Pick up the motor with the terminals properly orientated and carefully start to slide the motor over the rotor can. The resistance 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 0-ring might move out of position. • Line up the bolt holes, reinstall the bolts, and tighten in a cross-pattern. 8.1.3. After Installation into piping • Carefully open shutoff 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 contaminating the electrical box. • Before starting the pump, the system (and pump) must be filled with fluid, and air completely bled out of the system. For proper operation, pressure must be maintained on the suction side of the pump.The pump does not have screws for bleeding the air, as it is automatically bled as a function of the design of the pump. Temporary air in the pump will generate noise that disappears after a short time. WARNING! • The maximum system pressure is 145 psi (1 MPa or 10 Bar) • The pump must always be filled with system fluid as it is water lubricated and water cooled • The motor stator openings and stator housing (Figure 7) should not be insulated since the thermal insulation may prevent motor cooling and prohibit condensate from escaping from the motor housing when used in high humidity environments where the fluid temperature is below the motor temperature. RECEIVED 02/07/2019 7 ASPEN BUILDING DEPARTMENT 9. ELECTRICAL CONNECTIONS Connection of the pump must comply with local electrical codes and be carried out by qualified personnel. Connection to the power supply is carried out with the enclosed connector, the mounting of which is shown in the picture accompanying the connector. When connecting the pump,the following must be considered: • Liquid tight power connection required to maintain IP44 enclosure rating. Use supplied thread adapter option for flexible or armored cable installations. • The power input cable must use a minimum wire size of 16AWG solid or multi-strand copper wire. • Local or national electrical code requirements supersede Taco's specification. • Install an electrical disconnect to comply with national electrical code. • Connection of the power supply electrical cable must be done in a manner that ensures it does not contact the motor housing and volute of the device, due to potential high temperatures of both. 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 carrying rated power and be properly fused. Grounding connection is essential for safety and should be connected first. Grounding is only meant for pump safety. System piping should be grounded separately. 10.

The selected value is confirmed using the [✓] key. 10 5 Mode Descriptions The pump can operate in 5 different modes.We can set the pump in the most appropriate mode,depending on the system where the pump operates. The pump modes are: • Automatic Mode(factory default) • Proportional Pressure (increased differential head as flow increases) • Constant Pressure(constant pressure as flow increased) • Constant Speed(user selectable to match system requirements) • Combined Mode(all mode indicators are off) To switch between modes (except night mode) press and hold the [✓]key for 3 seconds then select [+]or[—]key.Once desired mode is selected,press the[i]key to confirm. • H Automatic Mode Hset In automatic mode the pump automatically sets the operating pressure,depending on the hydraulic system. By doing so,the pump finds the optimal operating position. The parameters cannot be set;they can only be scrolled through.This mode is recommended in most systems. Hset*HQ%� Proportional Pressure • The pump maintains the pressure with relation to the current flow.The pressure is equal to the set Proportional Pressure pressure(Hset on the drawing)at maximum power;at 0 flow it is equal to HQ %(default 50%, HQ %can be set on the pump webpage)of the set pressure. In between,the pressure changes linearly, relative to A the flow. In regulated mode we can only set the pump pressure(Hset on the drawing).We can only scroll -Ma: through the other parameters. Constant PressureThe pump maintains the currently set pressure(Hset on the drawing),from 0 flow to maximum power, M where the pressure begins to drop.At constant pressure,we can only set the pressure(Hset on the drawing)which the pump will maintain.We can only scroll through the other parameters. Q► Constant Pressure Constant Speed The pump operates with the currently set speed (RPMset on the drawing). In the unregulated mode,we H __ can only set the speed at which the pump will operate.We can only scroll through the other parameters. Combined Mode Multiple limits can be set only over the web interface. None of the other modes are on. M/' NightMode When the pump operates in night mode, it automatically switches between the selected Constant Speed operating mode and night curve. The transition to the night mode depends on the fluid temperature in the system.When the night mode is enabled, its icon illuminates and the pump operates in the selected operating curve of the mode.When the pump identifies the media temperature falling by 60 to 70 F° (15-20 C°)over a 2 hour time period,tie i nit rt\ starts to blink and the pump switches to the night curve.When the fluid temperature rises again,the icon stops blii�g the pump switches to the operating curve in the selected operating mode. The night mode operates only in combina_oh vvit the above indicated modes. It is not an independent operating mode. 0 2/0 7 t2 019 ASPEN BUILDING DEPARTMENT 10.6 Restoring Factory Settings To restore factory defaults, press and hold all three buttons for 5 seconds.

COM/OV RS-485 common and analog input common (ground). 17.2 Bus Topology The VR Control is a Modbus slave, connected directly to a Modbus RTU network. Connection can be made in either daisy chain style(if cabling allows such a connection)or a limited length passive tap. Schematic example is in Figure 6. Slave 1 Master Slave 2 Slave 3 t r /\ /� 3 r o a ro ' Passive tap Daisy chain Figure 6: Example of Modbus network Typically,only one master device is connected to the serial bus, and one or several slaves are also connected to the bus. Slaves do not communicate with each other and will never transmit data without receiving a proper request from the master device. Up to 32 single load devices can be connected to one RS-485 Modbus system without using a repeater.As this module is a 1/8 load device, up to 256 modules can be connected to the bus. Repeaters can be used to extend the maximum transmission distance and increase device count if needed. 17.3 Connection to Modbus A screened,twisted-pair cable should be used.The cable screen must be connected to the COM terminal and connected to safety ground at one point. 17.4 Speed, Party and Address By default,each device is set to 19200-E-1 (even parity),address 245. Properly set registers in section "7.7 Controller Configuration register block"to configure each device before connecting it to existing network. Optionally power each device one by one, configuring the settings before adding an-other one. There are several ways to restore forgotten Modbus connection settings: 1) Configure the module over Web interface. See section 6"Ethernet". 2) Reset the module to factory defaults. See Mode 9,section"4.3 Module mode selection". 3) If only address is unknown, Modbus"broadcast" (0x00)address can be used to write new address. Use care- fully as the value will be written to all connected devices. 17.5 Termination Control module contains neither termination nor bias circuitry. RS-485 wiring should be externally terminateq deF ), 02/07/2019 28 ASPEN BUILDING DEPARTMENT For short wiring and/or low baud rate, interface can operate without termination. However it is recommended that termination (-150 ohm resistor)is added on both ends of bus wiring.

Keep them short, below 250m combined for maximum speed and reliability. 17.6 Register Block Overview Controller Modbus RTU registers are grouped in the following register blocks: Start address Register block Readable/Writable Description 001 Controller configuration RNV Configuration of the Controller module. 021 Controller status R Status registers for the Controller module. 101 Pump control RAN Pump control registers. 201 Pump status R Status data from the pump. 301 Pump data R Measured data from the pump. All addresses contain 16 bit(one Word) registers. Some are bit interpreted while others are combined for a 32 bit value. NOTE: All register addresses are 1-based.Address 001 is thus transmitted over bus as 0x0000. 17.7 Controller Configuration Register Block Registers in this block are read with either function codes 0x03 or 0x04.They can be written as holding registers with function codes 0x06 and 0x10. NOTE:All values in this block are stored in nonvolatile memory immediately after write.
