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® ZN.520 controller. Factory built assures all piping packages are fully tested under water for leaks and are built within strict tolerances.
General Data 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.

General Data 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.

Controls Control Options UniTrane® fan-coils are available with four different control options: • Manual three-speed fan switch • Tracer ZN.010 • Tracer ZN.510 • Tracer ZN.520 Manual Fan Mode Switch Model Number Digit 30 = A and Digit 31 = D or K The manual fan mode switch is available for fan-coil units that do not have Trane factory-mounted control packages. This four-position switch (off, high, medium,low) allows manual fan mode selection and is available unit or wall mounted.
Controls Sequence of Operation Fan Speed Switch Off: Fan is turned off, two-position damper option spring-returns closed. option cycles to maintain setpoint temperature. Fresh air damper option is open. High, Medium, Low: Fan runs continuously at the selected speed. The twoposition damper option opens to an adjustable mechanical stop-position. ZN.520 Off: Fan is off; control valve options and fresh air damper options close. The low air temperature detection option is still active. ZN.010 and ZN.
Controls General Information Table C-1. Controller Input/Output Summary ZN.010 ZN.510 ZN.
Controls Zone Sensor Options Zone Sensor Options Zone sensors are available as either unit, wall, or split-mounted options for design flexibility. Fan-coils with the unit-mounted zone sensor option include a thermistor in the unit’s return air path. Wall-mounted zone sensor options have an internal thermistor. Zone sensors operate on 24 VAC. ZN.
Controls 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.
Controls 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.
Controls 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 1/2-inch sweat connections. The two-way valve option will either fully open or close.
Controls Control Valve 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.

Mechanical Specifications UniTrane® Fan-Coil Mechanical Specifications Performance Data Capacity: Unit capacities are certified under Industry Room Fan-Coil Air Conditioner Certification Program in accordance with ARI Standard 440-97. Safety: All standard units are UL listed in the United States and Canada and comply with NFPA 90A requirements. Construction All Units The unit includes a chassis, coil(s), fan wheel(s), fan casing(s), fan board and motor(s).
Mechanical Specifications body from piping. Use some means, such as a pump and chiller bypass, to ensure the maximum closed off DP rating of the two-way valves is not exceeded. Three-Way, Two-Position Control Valves Normally open three-way, two-position valves are rated for a maximum 25 psig (207 kPa) pressure differential across the valves. Normally closed three-way twoposition valves are rated for a maximum pressure differential across the valves of 15 psig (103 kPa).
Mechanical Specifications Disconnect Switch A unit mounted disconnect switch is available as a standard option on all units. Colors Six decorator colors are available in a baked powder finish. For a color chart, contact your local Trane office for a copy of UNT-S-10. Extended End Pockets On vertical or horizontal cabinet units, an 8” (20 cm) extended end pocket is available on the piping end.
Mechanical Specifications Options 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.

Controls Basic Series Accessories Manual Three-Speed Fan Switch The manual three-speed fan switch is a simple four-position switch (OFF-HI-MED-LO) which allows fan mode selection. The fan switch is wall-mounted and controls the fan motor by line voltage. Off: Fan is turned off. Hi, Med, Lo: Fan runs continuously at the selected speed setting.
Electrical Data Basic Series Electric Heat Electric Heat Features • All basic series fan-coil units are UL approved. • Units require only a single-point electrical connection. • 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.
