Features and Benefits Features and Benefits The ThinLine Advantage ThinLine horizontal fan coils combine features most desired in a fan coil by building owners, specifying engineers and contractors alike. The result is a fan coil design that meets the needs of all three. For building owners ThinLine fan coils offer quiet and energy efficient operation. They fully comply with ASHRAE 62.1-2010 standards for high indoor air quality.
Options and Accessories Options and Accessories Model Configurations Hideaway units model FCHH open or duct collar option. Cabinets are made of heavyduty steel and insulated with ½" thick Tuf-Skin® fiber glass insulation suitable for air stream applications. Optional ¼" antimicrobial-treated closed-cell insulation is softwareselectable. Cabinets are of generous size allowing for all necessary appurtenances, including factory-installed controls and piping packages, to be covered and easily accessible.
Options and Accessories Options and Accessories Options Cabinet Color Options Discharge (supply) Air Grille . A stamped-steel supply air grilles are standard for both front and bottom discharge. Also available is a double deflection grille for front discharge units. Motor option Tamper-proof Cabinet Option This option can be factory-installed on cabinet units to prevent access to unit controls and unauthorized removal of cabinet panels. It includes torx head screws for cabinet panels.
Options and Accessories Control Options Manual 4-Position Fan Switch Several styles of the fourposition fan switch (Off, High, Med, Low) are available for unit-mount, remote- or wall-mount. The remote-mount option operates on low-voltage or line-voltage power and can be provided with a factory-mounted, low-voltage interface board, which contains (3) 24-volt relays with linevoltage contactors and terminal connections. The transformer is factory-installed and wired.
Options and Accessories T170 Thermostat with Digital Display T180 Programmable Thermostat Two thermostats are offered for remote installation only: TA170 for three-speed fan control and TB170 for staged fan operation. Both thermostats are used for OnOff control of low- or line-voltage valves with auto changeover.
Options and Accessories MicroTech Controllers ThinLine fan coils can be provided with unitmounted MicroTech controllers and multiple unit- or room-mounted sensors. MicroTech controllers can only be used with remote room sensors (described below) and not with remote thermostats. A MicroTech controller is able to operate in either a stand-alone non-communicating environment or a communicating environment.
Options and Accessories Factory Valve & Piping Packages Factory valve and piping packages are available for both two-pipe and four-pipe systems with either right or left hand connections. Four-pipe systems can be configured with the heating and cooling connections on the same or opposite sides of the unit. Packages can be either factory-installed or factory-assembled and shipped loose with the unit. All factory-assembled packages are fully leak tested.
Options and Accessories Enhanced Packages Deluxe Packages Enhanced valve and piping packages add a strainer to the Basic package supply water pipe. The strainer is attached to the supply water pipe at the coil connections. The strainer body is cast brass construction with a stainless steel mesh that is easy to remove for cleaning. Deluxe valve and piping packages add a strainer to the Premium package. The strainer is available with or without an optional draining (blow-off) valve.
Options and Accessories Control Valve Options Except for Shut-off Only packages, all valve and piping packages include control valves for controlling water flow. All Daikin control valves are factory assembled and mounted in the supply water pipe downstream of the coil . Several options are available: Two-Way Modulating Valves . Two-Way/Two-Position Valves . Three-Way Modulating Valves . Three-Way Two-Position Valves .

Unit Selection Unit Selection To achieve an efficient fan coil system, accurate system design and proper equipment selection is necessary. Variations, limitations/control of fan coil systems, design conditions and design load calculations are not described in detail in this catalog. More detailed information may be found in the ASHRAE Guide.
Performance Data PSC Performance Data PSC Two-Pipe Systems All performance measured on high speed tap, 115 V, at 0.05" ESP for hideaway fan coils and 0.0" ESP for cabinet fan coils. Cabinet units were tested with bottom return/front discharge configurations. Cooling performance is based on 80/67°F (27/19°C) entering air temperature, 45°F (7°C) entering chilled water temperature with a 10°F (5.5°C) temperature rise.
Performance Data PSC Performance Data PSC Four-Pipe Systems - Hot Water Preheat or Reheat (Standard or High Capacity) All performance measured on high speed tap, 115 V, at 0.05" ESP for hideaway fan coils. Cooling performance is based on 80/67°F (27/19°C) entering air temperature, 45°F (7°C) entering chilled water temperature with a 10°F (5.5°C) temperature rise.
Performance Data PSC Four-Pipe Systems - Steam Preheat or Reheat All performance measured on high speed tap, 115 V. Medium and low-speed capacities are approximately 88% and 68% respectively of the high-speed capacity. Q/ITD = MBh (kW) Saturated steam temp – Entering air temp To determine heating capacities at different entering steam pressure or entering air temperature, compute the new Inlet Temperature Differential (ITD) and multiply it by the Q/ ITD shown.
Performance Data PSC Air Volume Capacity Data . Air volumes shown in the table are measured with a dry coil at the motor speeds indicated with 115v/60/1 electrical power, with a 1" throwaway filter installed, and with a rear return/ front discharge cabinet unit configuration.

Performance Data ECM Performance Data ECM Performance Cooling and Heating – 2- and 4- Pipe Air volumes shown in the table are measured at the motor speeds indicated with 115v/60/1 electrical power, with a 1" throwaway filter installed, and with a stamped discharge grille on a horizontal cabinet unit or a discharge duct collar on a hideaway unit at approximately 0.05 inch of pressure drop.
Electrical Data Electrical Data MCA (Minimum Circuit Ampacity), MOP (Maximum Overcurrent Protection) or MFS (Maximum Fuze Size) Calculations HACR (Heating, Air-Conditioning and Refrigeration) type circuit breakers are required in the branch circuit wiring for all fan coils with electric heat. The minimum circuit ampacity (MCA) is the minimum wire size required for a field-wired product.
