Features and Benefits

The UniTrane® fan-coil meets the standards of today’s market, as well as the anticipated needs of tomorrow’s market. The tradition that company founder Reuben Trane began 60 years ago continues with the latest generation of fan-coils from The Trane Company.

The UniTrane

fan-coil is the leader in

these key areas:

• Indoor Air Quality (IAQ)

• Controls

• Flexibility

• Quality

• Serviceability

Today’s HVAC market is concerned with issues such as indoor air quality (IAQ) and CFCs that demand a change in HVAC products. In addition, renovation has overtaken new construction in the fan-coil market—demanding a design that caters to renovation issues. Trane is concerned with these issues, too. That’s why we designed the UniTrane fan-coil as an integral part of the company’s system solutions with standard IAQ-related features that fully comply with ASHRAE 62.

IAQ Design

• Closed-cell insulation is standard on all units to help prevent fiberglass in the airstream.

• The main and auxiliary drain pans are constructed of a noncorrosive engineered plastic (ABS and CyColac T).

• The main and auxiliary drain pans are positively sloped in every plane to assure proper drainage and help maximize protection from microbial growth.

• The drain pans are removable for cleaning.

• Easy filter access encourages frequent changing.

• The auto-economizer damper option allows free cooling and ventilation to help comply with ASHRAE 62—and save energy and operating costs.

• UniTrane fan-coils have a blow-thru design. Low vertical units are drawthru.

Controls

• All controls are factory-mounted and tested to minimize field setup.

• Controls are wired with a 24 VAC transformer to keep only a single source power connection requirement to the unit.

• All wall-mounted zone sensors require only low voltage control wiring from the device to the unit control box. (No line voltage.)

• The Tracer

controls family introduces the latest in control technology with the ZN.010, ZN.510, and ZN.520 controllers.

• The controller automatically determines the unit’s correct operating mode (heat/ cool) by utilizing a proportional/integral (PI) control algorithm to maintain the space temperature at the active setpoint, allowing total comfort control.

• Entering water temperature sampling eliminates the need for inefficient bleedlines to sense automatic changeover on two-pipe changeover units.

• The random start-up feature helps reduce electrical demand peaks by randomly staggering multiple units at start-up.

• Occupied/unoccupied operation allows the controller to utilize unoccupied temperature setpoints for energy savings.

• Warm-up and cool-down energy features are standard with Trane controls.

• Continuous fan or fan cycling is available with ZN.010 or ZN.510.

• Monitor unit operation using Tracer

Summit building management system with ZN.510 or ZN.520.

• To customize unit control, Tracer Summit or Rover

™

software will allow field modification of ZN.510 and ZN.520 default settings. For ZN.010, use Rover to field modify default settings.

• Maximize fan-coil system efficiency with free cooling economizers and modulating valves on units with ZN.520.

Flexibility

• Two, three, and four-row coils allow greater design flexibility in two and four-pipe systems.

• One-row steam or hot water reheat coils for dehudification on units with ZN.520 controls.

• Fan motors are available for either high static (0.4-inch external static pressure) or free discharge applications.

• Piping is factory assembled, mounted and tested. Units are also available without piping. Reheat coil piping is available on 2-pipe units with hot water reheat coils and either a fan speed switch or Tracer ZN.520.

• Factory piping options include interconnecting piping, control valves, and end valves. Deluxe piping also has unions and a strainer.

• Control options range from a simple fan speed switch to a DDC controller that can tie into a Tracer Summit

building

automation system.

• An 8-inch (20 cm) extended end pocket is an available option on the piping end of cabinet style units.

• Slope-top vertical cabinet units are also available for school and dormitory applications to prevent items from being placed on top of the units.

Quality

• Coils and piping packages are air and leak-tested before mounting on the fancoil.

• Coil piping connections are also air and leak-tested after mounting on the unit.

• All control end devices and moving components (fans and motors) are computer-tested after units are complete.

Serviceability

• Filters are easily removable and changed without removing the front panel on vertical cabinet units.

• Motors are easy to disconnect from the fan board, allowing easy service.

• The main and auxiliary drain pans are easily removable and wipe clean with a wet cloth.

• The manual output test function is an invaluable troubleshooting tool. By simply pressing the test button on the

ZN.510, ZN.520, or ZN.010;

Tracer service personnel can manually exercise outputs in a pre-defined sequence.

Piping Packages

Factory-Installed Piping Packages

UniTrane® fan-coils have standard piping packages available as a factory built and installed option, for the main coil. Piping package options are also available for the hot water reheat coil on two-pipe units equipped with either a fan speed switch or Tracer assures all piping packages are fully tested under water for leaks and are built within strict tolerances. Factory-installed means that chilled and hot water pipes are the only field connections required. The installer doesn’t have to sweat connect piping packages onto coil connections in a tight end pocket. Field connections are brought to a point near the exterior of the unit for easy access. All piping and components are located to allow condensate to drain into the auxiliary drain pan. Insulation of the factory piping package is not required. However, all field connections should be insulated to prevent condensation from missing the auxiliary drain pan.

Piping Package Components

UniTrane piping packages consist of a variety of components for each applica-

tion. The following section provides a detailed description of each of the piping components. Following this section are additional illustrations and specifications.

Piping System/Placement

Factory piping systems are available for either two or four-pipe systems with right or left hand connections. Four-pipe systems have both the heating and cooling connections on the same side of the unit. A simple coil connection (a unit without a piping package) is also available in either a right or left hand configuration for those applications requiring field piping.

Interconnecting Piping

Interconnecting piping refers to the copper piping which is attached to the coil connections and to which all other components (control valves, end valves, etc.) are attached. Piping is OD copper. Two-pipe piping extends near the unit exterior to one inlet and one outlet connection.Four-pipe units have two sets of piping that extend near the unit’s exterior—one inlet and one outlet

each for both chilled and hot water. A label identifying connection points clearly marks both chilled and hot water on every unit.

Deluxe or Basic Piping Package

The basic piping package includes only the main components of the piping package: interconnecting piping, control valves, and end valves.

The deluxe piping package also includes a strainer on the entering water pipe and unions at the coil connections along with the basic components. The strainer body is cast brass construction, with a stainless steel mesh strainer that is easily removed for cleaning. The unions are forged brass construction and close with a minimum amount of effort.

End Valves

Each piping package includes a ball valve for the entering water pipe and one of the following end valves on the leaving water pipe: ball valve, manual circuit setter, or an auto circuit setter. These valves serve as the field connection points on all UniTrane piping packages.

• Ball Valves

Ball valves, also known as stop or end valves, allow the unit to be cut off for service purposes. These valves have a two-inch handle that rotates 90 degrees to a fully open position. The valve body is cast brass, and the ball is polished brass with a Teflon seat. Ball valves are available as end valves on both the entering and leaving water pipes.

Piping Packages

Manual Circuit Setter

In lieu of a ball valve on the leaving water pipe, a manual circuit setter, also known as a manual flow control valve, acts as both a flow setting device and a stop valve. This valve allows water flow through the fan-coil unit to be set quickly and accurately.

The manual circuit setter includes Schrader ports in the valve body. These ports are used to measure the pressure drop across the valve. This pressure drop can be compared to factory supplied curves that relate the pressure drop to a specific flow rate. This valve also has a memory stop so the correct setting can be found quickly.

Auto Circuit Setter

An auto circuit setter is an automatic flow control device available on the leaving water pipe. The auto circuit setter includes a cartridge within the valve body that is sized to allow a specific flow rate through the coil. This valve sets flow through the coil without any action required by a system piping balancer. The auto circuit setter is available on the leaving water pipe with a ball valve.

The auto circuit setter also includes two P/T’s plugs in the valve body to allow

measurement of the pressure drop temperature through the valve.

Control Valves

Piping packages are available with or without control valves. All control valve options are factory mounted and wired to the UniTrane

• Two-Way/Two-Position Valves

These valves will either fully open or close in response to a 24VAC signal from the Trane controller. Main control valves are direct-acting valves, while the auxiliary valves are reverse-acting. All control valves are factory mounted in the leaving water pipe downstream of the coil. Some means of relieving pump head pressure should be accounted for when two-way valves are selected. Normally open or normally closed valves are available.

• Three-Way/Two-Position Valves

These valves will either allow full water flow through the coil or divert the flow through a bypass line. The valves respond to a 24VAC signal from the Trane controller. Main control valves are direct acting valves, while the auxiliary valves are reverse-acting. All three-way valve packages include a balance fitting

fan-coil controls.

in the bypass line to allow flow balancing in the bypass position. Three-way valves are factory mounted in the leaving water pipe downstream of the coil. Normally open or normally closed valves are available.

• Two-Way Modulating Valves

These valves modulate the water flow through the coil in response to a signal from the Trane controller. All modulating valves are three-wire floating point equal percentage valves. The modulating valves are factory mounted in the leaving water pipe downstream of the coil.

• Three-Way Modulating Valves

These valves modulate the water flow through the coil in response to a signal. Three-way valves allow water that is directed through the coil to mix with water that is directed through the bypass line. This mixture exits through the leaving water pipe. All modulating valves are three-wire floating point equal percentage valves. The modulating valves are factory mounted in the leaving water pipe downstream of the coil.

Selecting the Correct Modulating Valve Size

Modulating valves are available in any of four port sizes. These four port sizes relate to a Cv of 0.7, 1.5, 2.5 or 4.0, which is the coefficient of flow. The coefficient of flow is defined as the volume of water flow through a control valve in the fully open position with a 1 psig (6.895 kPa) differential across the valve. It is calculated using the following formula: Cv = Q/Square root ∆P where: Cv = flow coefficient Q = flow rate (GPM) ∆P = pressure drop across the valve or coil (psig).

For good control, the valve Cv should be approximately equal to the Cv of the water coil.

Modulating Valve Selection Example

Assume a size 06 fan-coil is selected to operate at the following conditions: Vertical Cabinet Fan-Coil Entering water temperature = 45 F (7 C) Leaving water temperature = 55 F (13 C) EAT conditions = 80/67. The coil is selected as a four-row coil. Select the best modulating valve size for this unit.

1 Find the ∆P across the water coil. Refer to the ARI performance table to determine the ∆P across the water coil (or use TOPSS™ selection program). The water pressure drop is found to be 7.0’ (20.9 kPa) of water at a flow rate of 3.74 gpm. This converts to a pressure drop of 3.03 psig (1.0 feet of water = 0.4328 psig.)

2 Calculate the Cv of the water coil. Cv = GPM/Square root ∆P. Cv = 3.74/Square root 3.03

Note:

1. CFM = Cubic feet per minute

2. TMBH = Total capacity (MBH)

3. GPM = Gallons per minute

4. WPD = Water pressure drop (feet of water)

5. Q/ITD = MBH (kW)/(Entering water temperature - Entering air temperature) when ∆T and GPM (L/s) remain constant. To determine heating capacities at a different entering water

temperature or entering air temp, compute the new ITD and multiply it by the Q/ITD shown.

6. Medium and low speed capacities are approximately 80 percent and 60 percent respectively of the high speed capacity.

7. High static motors need the appropriate length of duct to prevent poor acoustical applications.

This four-position switch (off, high, medium,low) allows manual fan mode selection and is available unit or wall mounted. The unitmounted option (Digit 31 = D) operates on line voltage. The wall-mounted option (Digit 31 = K) is low-voltage and has three 24 volt relays using a factory-wired transformer and relays to control the fan motor.

Tracer® Controls

The Tracer family of controllers, ZN.010; ZN.510; and ZN.520, offer the combined advantages of simple and dependable operation with the latest Trane-designed controller. Standard control features include options normally available on more elaborate control systems. All control options are available factory-configured or can be field-configured using Rover to the Trane publication,

Tracer ZN.010 Model Number Digit 30 = E

Tracer ZN.010 is a stand-alone microprocessor controller.

Tracer ZN.510 Model Number Digit 30 = F

ZN.510 can be used as either a stand-alone or communicating microprocessor controller.

Tracer ZN.520 Model Number Digit 30 = G

The ZN.520 controller can be used in a stand-alone application or as part of a Trane Integrated Comfort

In the stand-alone configuration, ZN.520 receives operation commands from the zone sensor and/or the auto changeover sensor (on auto changeover units). The entering water temperature is read from the auto changeover sensor and determines if the unit is capable of cooling or heating. The zone sensor module is capable of transmitting the following information to the controller:

• Timed override on/cancel request

• Zone setpoint

• Current zone temperature

• Fan mode selection (off-auto-high-med-low)

For optimal system performance, fan-coil units can operate as part of an Integrated Comfort™ System (ICS) building automation system controlled by Tracer Summit The controller is linked directly to the Summit control panel via a twisted pair communication wire, requiring no additional interface device (i.e., a command unit). The Trane ICS system can monitor or override ZN.520 control points. This includes such points as temperature and output positions.

Fan speed control in the auto

Auto setting allows the modulating (three-wire floating point) control valve option and three-speed fan to work cooperatively to meet precise capacity requirements, while minimizing fan speed (motor/ energy/acoustics) and valve position (pump energy/chilled water reset). As the capacity requirement increases at low fan speed, the water valve opens. When the low fan speed capacity switch point is reached, the fan switches to medium speed and the water valve repositions to maintain an equivalent capacity. The reverse sequence takes place with a decrease in required capacity.

Low, Medium, High: The fan will run continuously at the selected speed and the valve option will cycle to meet setpoint.

Control Features

The following control functions are standard features on units with Tracer ZN.010, ZN.510, or ZN.520.

Entering Water Temperature Sampling Function

A system that uses a two-way control valve option might not sense the correct entering water temperature during long periods when the control valve is closed. If the demand for heating or cooling does not exist for a long period, the entering water will eventually approach ambient temperature.

Using the entering water temperature sampling function, the controller provides accurate two-pipe system changeover—without sacrificing the benefits of two-way control valves. Also, it eliminates inefficient bleed or bypass lines that can allow unnecessary waterflow through the system.

This function periodically samples the entering water temperature by opening the hydronic valve. The valve opens for 20 seconds to allow the water temperature to stabilize. Then the controller reads the entering water temperature for up to three minutes to see if the correct water temperature is available for the selected operating mode.

The entering water temperature must be five degrees or more above the space temperature to allow hydronic heating and five degrees or more below the space temperature to allow hydronic cooling. If the correct water temperature for the operating mode is available, the unit begins normal heating or cooling operation. If the correct water temperature is not available, the controller closes the control valve and waits 60 minutes before attempting to sample the entering water temperature again.

A factory-mounted thermistor senses the entering water temperature on changeover cooling/heating coil units. If the fan-coil has a factory-mounted piping package, the sensor is strapped to the entering water pipe. If the fan-coil does not have a piping package, the sensor is coiled in the end pocket for mounting on customer-supplied piping. This sensor must detect accurate water temperature for proper changeover.

Automatic Heat/Cool Mode Determination

The controller automatically determines whether heating or cooling is needed— based on space and system conditions. Utilizing a proportional/integral (PI) control algorithm to maintain the space temperature at the active heating or cooling setpoint. The controller measures the space temperature and active setpoint temperature to determine the unit’s heating or cooling capacity (zero to 100%).

Occupied/Unoccupied Operation

The occupancy input utilizes a binary switch (i.e. motion sensor, timeclock, etc.) that allows the zone sensor to utilize it’s unoccupied internal setpoints.

Random Start

This feature randomly staggers multiple unit start-up to reduce electrical demand spikes.

Warm-up

The two-position fresh air damper option closes during the occupied mode when the space temperature is three degrees or more below the heating setpoint temperature. The damper remains closed during warm-up until the space temperature is within two degrees of the heating setpoint temperature.

Cool-down

The two-position fresh air damper option closes during the occupied mode when the space temperature is three degrees or more above the cooling setpoint temperature. The damper remains closed during cool-down until the space temperature is within two degrees of the cooling setpoint temperature.

Manual Output Test Function

This feature is an invaluable tool for troubleshooting a unit. By simply pressing the controller’s test button, service personnel can manually exercise outputs in a pre-defined sequence.

Peer to Peer Communication (ZN.510 and ZN.520)

Peer to peer communication allows multiple units in one space to share the same zone sensor and provide simultaneous heating and cooling. The ZN.510 or ZN.520 controller can share information between units on the same communica-

tion link using a twisted pair wire in the field. Unit configuration must be modified with Rover service tool.

Economizing Control (ZN.520)

With the controller configured for economizing control, it will calculate the required cooling capacity every ten seconds and modulate the damper option open to the calculated position. If the setpoint is not satisfied, the damper will continue to open until the setpoint condition has been met or the damper is 100 percent open. If this still does not satisfy the setpoint, the cooling valve option will begin to open and try to satisfy the load requirements. Once capacity exceeds the load requirements, the valve will begin to close until the setpoint has been reached or the damper reaches its minimum position, which is field-adjustable. This option uses a three-wire, floating point damper actuator.

A thermistor to sense discharge air is factory mounted near the discharge surface of the last coil for use in economizing and cascade temperature control. Summit value as a read-only point. Cascade temperature control uses both the zone and discharge air temperatures to more accurately calculate the required unit capacity.

A thermistor to sense fresh air is factory mounted at the unit’s fresh air opening for use in economizer applications or as a read-only point for Summit. If the fresh air temperature is a read-only value, it will not impact the control algorithm. In an economizer application, a fresh air temperature signal must be provided either by this thermistor or Summit.

Features

ZN.520 Additional Features

Automatic Ventilation Reset

To ensure proper ventilation rates, the controller is configured with two fresh air damper minimum position setpoints for occupied operation. As the fan speed changes to low or high, the damper modulates to maintain the correct ventilation rate for the space. The damper position does not change when the fan speed changes to medium.

Fan Status

The ZN.520 controller monitors the fan output status to determine if the fan is operating.

Filter Maintenance Status

The controller has an adjustable timer that indicates through Summit or Rover when filter maintenance is necessary. Filter maintenance status is based on cumulative fan run hours.

Dehumidification

When the fan-coil unit is equipped with a reheat coil and humidity sensor, the controller will keep humidity levels within an acceptable range. This feature helps reduce the risk of microbial growth and damage to building interiors.

Water Valve Override

Using Summit or Rover, the water valve override function drives all water valves in every unit fully open simultaneously. This helps reduce the time required for waterside balancing.

Cascade Control

The controller maintains discharge air temperature using a cascade control algorithm. The discharge air temperature is based on the difference between the space temperature and setpoint. Unit capacity modulates to achieve the discharge air temperature.

Interoperability

The ZN.520 controller can be used with a Tracer Summit system or on other control systems that suport LonTalk and the SCC profile. For more information on specific inputs and outputs, see the

End Device Options

All end device options are factoryinstalled and tested.

Two-Position Control Valves Model Number Digits 27 and 28 = A - H

Two-position valve options are available with either Tracer ZN.010, ZN.510, or ZN.520. Valves are spring-return type, sweat connections, and available as normally open or closed. The valves respond to a 24V signal and have sweat connections. The two-way valve option will either fully open or close. The three-way valve option allows either full water flow through the coil or diverts waterflow through the bypass. If the control valve loses power, the valve returns to its de-energized position. All control valve options are factory installed in the leaving water piping downstream of the hydronic coil. The valve actuator is easily removable for service without removing the valve body from piping.

when the power loss occurred. All control valves are factory installed in the leaving water piping downstream of the hydronic coil.

Field-Supplied Valves Model Number Digits 27 and 28 = X or Y

When using field-supplied valves, this option allows the controller to be factoryconfigured for the normal position of the field-supplied valve.

Note: The Trane Company does not recommend wild coil applications.

Two-Position Fresh Air Damper Actuator Model Number Digit 13 = D, E, or F (Available with all control options except ZN.520)

This damper actuator uses a 24V signal and is factory-wired and mounted to the damper assembly. It allows zero to 50% fresh air. The damper will drive open to an adjustable mechanical stop-position whenever the fan is running during occupied mode and will spring-return closed when the fan turns off.

Note: The Trane Company recommends using the low temperature detection option with fresh air dampers to detect possible freeze conditions.

Two-Position Fresh Air Damper Actuator

Economizer Fresh Air Damper Actuator

Economizer Fresh Air Damper Actuator (ZN.520) Model Number Digit 13 = G, H, or J

This option is a three-wire floating point, spring-return damper actuator and is factory-wired and mounted to the damper assembly. When the controller enables the economizer and the unit is in occupied mode, the fresh air damper modulates between its minimum position (editable) and the full open position to maintain setpoint temperature. If economizer operation stops or if the unit is in the heating mode, the fresh air damper adjusts to its minimum position.

Note: The Trane Company highly recommends using the low temperature detection option with a fresh air damper to detect possible freeze conditions.

Low Temperature Detection Model Number Digit 36 = 2

When the low temperature detection device senses an entering air temperature of 36 F to the hydronic coil, the normally-closed switch opens a corresponding set of binary input terminals. The fan disables, control valves open, and the fresh air damper closes.

Thirty minutes after the diagnostic, Tracer ZN.010, ZN.510, or ZN.520 uses an automatic reset function to attempt to reset the unit. If the diagnostic occurs again within 24 hours after an automatic

diagnostic reset, the unit will require a manual reset. This function attempts to resolve the infrequent nuisance alarm.

The low temperature detection device is an averaging type capillary tube and will reset when it detects an entering air temperature of at least 44 F.

Condensate Overflow Detection Model Number Digit 35 = 2

A float switch is factory-supplied for field installation in the auxiliary drain pan to detect a high condensate water level. When the float switch rises, the normally closed input opens a corresponding set of binary input terminals. This also causes the fan to disable, and the control valve and fresh air damper options to close. Although the float switch will close when the high condensate level recedes, the controller must be manually reset before normal unit operation can occur. If using a ZN.510 or ZN.520 controller you can reset using Summit. Use Rover service software to reset units with ZN.010, ZN.510, or ZN.520.

Sub-bases elevate vertical cabinet or slope top cabinet units to a specified height; for example, to reach the bottom of a window sill. The sub-base also provides a cavity through which to run piping underneath the fan-coil unit. Subbases are 16-gauge steel construction and have the same black paint finish as the unit’s base. The sub-base is available in heights between 2 - 7” (5 -18 cm) in

/2” (1 cm) increments. The sub-base depth and width is identical to the unit’s dimensions.

Mechanical Specifications

False Backs

False backs increase the depth of a vertical cabinet unit and provide a cavity through which to run piping behind the fan-coil unit. False backs are also an excellent application when installing a unit beneath a window sill that extends out past the front of the unit.

False backs are 18-gauge steel construction and have the same paint finish as the unit. The false back is available in depths between 2”- 8” (5 - 20 cm) in 1” (2.54 cm) increments, with height and width identical to the unit’s dimensions.

Recessing Flanges

Recessing flanges have 18-gauge steel construction and are painted the same finish as the unit. Recessing flanges provide an aesthetic architectural border or frame around vertical and horizontal cabinet fan-coil units.

Aluminum Wall Boxes

Wall boxes have a clear anodized finish and include a single core wire mesh insect screen. The frame is 10-gauge extruded aluminum alloy 6063-T5 construction. Horizontal louvers have 16gauge extruded aluminum alloy 6063-T5 construction.

Wall boxes ship separate for field installation. A field supplied duct or sleeve from the wall box to the unit fresh air opening is required to provide fresh air.

Wall boxes are sized to handle up to 100% of nominal air flow.

Projection Panels

Projection panels allow semi-recessing of vertical recessed units.

Panels are 16-gauge steel construction, painted with a baked powder finish. They are available in projection depths ranging from 2”- 6” (5 - 15 cm) in increments. There is a distance of (2.2 cm) between the projection panel and the front of the unit.

• A unit mounted magnetic contactor(s) is (are) supplied on all unit voltages.

• A high temperature cutout with automatic reset de-energizes the electric heat in the event of an overheat condition.

• When hydronic heating is active, a lockout sensor will disable the electric heat.

Minimum Circuit Ampacity (MCA) and Maximum Fuse Size (MFS) Calculations for Fan-Coils with Electric Heat:

Heater Amps = (Heater kW x 1000)/Heater Voltage

Note: Use 120V heater voltage for 115V units. Use 240V heater voltage for 230V units.

MCA = 1.25 x (heater amps + all motor FLA’s)

MFS or HACR Type Circuit Breaker =

HACR (Heating, Air-Conditioning and Refrigeration) type circuit breakers are required in the branch circuit wiring for all fan-coils with electric heat. See the Electrical Data section for motor FLA’s.
