Residential applications include: Condominiums, apartments, student residences/dormitories, assisted living/retirement facilities, and military barracks.

T rane recommends the remote mounting of low voltage (24V) thermostats to achieve optimal zone control. When thermostats are remote mounted, a terminal strip is provided inside the unit for field connection to the remote thermostat. Unit mounting of thermostat is also available, however all thermostats are shipped loose for field installation after the unit is installed, drywall is applied and the walls are painted.

The standard standalone thermostats listed above cycle a two position (on/off) valve and feature discrete speed fan speed operation. If modulating (0-10V DC or 3-wire floating point) valve actuators or modulating or 0-10V DC EC motors are a requirement, a thermostat or controller with the necessary analog outputs must be used.

Tracer ZN521 Zone Controller

The T racer ZN521 is a factory-installed LonTalk® control board designed to provi de control of th e fan-coil products (see Figure 9).

Figure 9. Tracer ZN521 controller

Components and Options

Features include:

• Automatic fan-speed reset

• Automatic ventilation reset

• Manual output test

• Filter maintenance

• Master slave

• Water valve override

• Freeze avoidance

• Interoperability

• Three generic I/O ports

The Tracer ZN521 controller is designed to be used in the following applications:

• As part of the T rane T racer Summit building automation system, the T racer ZN521 becomes an important part of the Trane Integrated Comfort system (ICS).

• The Tracer ZN521 can function as a completely standalone controller in situations where a building automation system (BAS) is not present.

• For situations when a non-T rane BAS is present, the T racer ZN521 can be where ever a LonT alk front-end system is present.

Through building management of the HVAC system, optimizing energy consumption becomes possible at a zone level. Each unit is capable of functioning independently of one another during occupied and unoccupied hours of the day. This allows the temperature setpoint and ventilation setting to be changed automatically based on zone usage (see Figure 10).

Two Systems in One

In an ICS environment, the Tracer ZN521 is pre-designed to install quickly and easily into the system. Since the controller is mounted on the unit, the start-up time for the entire system is minimized. T rane becomes the single source of responsibility for the equipment, unit controls, and building automation system.

Once power is applied to the controller, it will automatically start up and run based upon the setpoint on the local zone sensor. The Tracer ZN521 is certified to the interoperable L Space Comfort Controller profile. This allows the controller to be used with another vendor’ s BAS and thereby still provide the high quality of factory installation. In addition, the Tracer ZN521 provides one of the most extensive interoperable data lists of any controller of its type in the industry.

Automatic Fan and Ventilation Reset

With the Tracer ZN521 controller, a multi-speed fan control for the fan coil delivers the airflow output customized to support the cfm space needs. When less cfm is necessary to meet the load of the zone (typically 75 to 80 percent of the time), the equipment operates on low speed. However, if the room temperature rises, the controller will switch to high speed.

18 UNT-PRC019-EN

Manual Output Test

The T racer ZN521 controller includes a manual output test function. This function may be initiated from the blue test push button on the controller or through the Rover™ service tool. This feature is used to manually exercise the outputs in a defined sequence.

The purpose of this test sequence is to verify output and end device operation. The manual output test function may also be used in the following situations:

• Reset latching diagnostics

• Verify output wiring and operation

• Force the water valve(s) open to balance the hydronic system during installation set-up or service.

ONMARK

Components and Options

Filter Maintenance

Filter status for the controller is based on the cumulative run hours of the unit fan. The controller compares the amount of fan run time against an adjustable fan run hour (stored in the controller) to determine when maintenance is recommended for the unit. The run-hours value may be user edited as required (through Rover). The valid range for the fan run hours limit is 0 to 5000 hours with a default of 600 hours. Once the run hours limit has been exceeded, the controller generates a maintenance required diagnostic (unit will not shut-down). The user will be notified of th is diagnostic through the building automa tion system or when a T rane Service T ool is communicating with the controller.

Master Slave (Data Sharing)

Because the Tracer ZN521 controller utilizes LONW receive data (setpoint, heat/cool mode, fan request, space temperature, etc.) to and from other controllers on the communication link with or without the existence of a building automation system. This applies to applications where multiple units might share one zone sensor for both stand-alone (with communication wiring between units) and a building automation system.

ORKS

technology, the controller can send or

Water Valve Override

The Tracer ZN521 can be commanded via the Rover service tool to open all hydronic valves 100 percent. This allows for the faster water balancing of each unit and the entire system when the command is sent globally to all controllers. A properly balanced system is essential for proper and efficient operation.

Hydronic Coil Freeze Protection (Freeze Avoidance)

Fan coil systems in cold climates need to take precautions to avoid hydronic coil freeze-up. The T racer ZN521 does this from three different aspects. Any of these methods of protections will result in the unit fan being disabled, the outside air damper being shut , and the hydronic valves being opened 100 percent.

The three methods of freeze avoidance include: 1 . A binary freeze protection thermostat is mounted on the coil and will cause a latching diagnostic

if the coil temperature falls below 35°F.

2. An analog discharge air sensor monitors the temperature of the air coming off of the coil and if the temperature falls below 40°F the outside air damper is closed, the fan is turned off and the valves are fully opened.

3. When in the unoccupied mode the Tracer ZN521 has an adjustable freeze avoidance setpoint. If the outside air temperature is below the setpoint the unit will open the valves to allow water to flow through the coils.

Interoperability

Interoperability allows the owner freedom to select multiple vendors, and multiple products. With this advantage, the owner can choose the best products, the best application, and the best service from a variety of suppliers to meet their evolving building control needs in a cost effective manner.

Generic Binary Input/Output

The three generic binary inputs/outputs are not part of the normal control, but are actually controlled through the Tracer Summit system (when present) to issue commands to the Tracer ZN521 control to turn the generic inpu ts/outputs of add-on equipment (suc h as baseboard heating, exhaust fans, occupancy sensor, lighting, etc.) on and off. This binary port is not affected when other binary diagnostics interrupt unit operation.

Tracer UC400 Controller

The T racer UC400 is a factory-installed BACnet® MS/TP control designed to pro vide control o f the fan coil (see Figure 11). The Tracer UC400 controller is designed to be used in the following applications: as stand-alone operation, part of the T rane T racer SC building automation system, or part of another BACnet MS/TP Building Automation System. The Tracer UC400 can function as a completely standalone controller in situations where a building automation system (BAS) is not present.

Features include:

• Single Zone VAV

• Automatic ventilation reset

• Filter maintenance

• Wa t er valve overri de

• Freeze avoidance

• Interoperability

• Unused I/O can be used as generic I/O

The T racer UC400 is designed to install quickly and easily into the system. T rane becomes the single source of responsibility for the equipment, unit controls, and building automation system. As a standalone controller, the T racer UC400 is ideally suited for fix-on-fail replacement of units with old pneumatic controllers, or in situations where a BAS will be added at a later date. Once power is applied to the controller , it will automatically start up and run based upon the setpoint on the local zone sensor. An individual time clock can be added to the unit for local scheduling. The Tracer UC400 is BTL listed as B-ASC profile. This ensures the controller to be use d with other BACnet building automation systems.

The Tracer UC400 controller delivers single zone VAV control and can be used in a stand-alone application or as part of a Trane Integrated Comfort™ System (ICS).

In the stand-alone configuration, Tracer UC400 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 coils can operate as part of an ICS building automation system controlled by T racer 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 T rane ICS system can monitor or over ride T racer UC400 control points. This includes such points as temperature and output positions.
