Vertical SeriesMotor DataThermal Overload ProtectionAll split-capacitor motors furnished by IEC contain internal thermal-overload protection. The overload automatically resetswhen the temperature returns to a safe limit. Electronics Testing Laboratories, Inc. approves the motor and thermal overloadcombination at locked rotor conditions only.Motor Performance Data – FHY, FXY, FSYVoltage115 V60 Hz1-Phase208 V60 Hz1-Phase230 V60 Hz1-Phase277 V60 Hz1-PhaseFan SpeedHighMediumLowHighMediumLowHighMediumLowHighMediumLowUnit Size 02 03 04 06 08 10 12Nominal HP 1/30 1/30 1/12 1/6 1/6 (2) 1/12 (2) 1/6Amps 0.53 0.83 1.40 2.50 2.50 2.80 5.00Watts 85 80 130 200 210 240 370Amps 0.31 0.48 0.70 1.30 1.30 1.30 2.50Watts 50 50 75 140 140 145 265Amps 0.27 0.33 0.47 0.57 0.61 0.40 1.25Watts 35 35 50 60 65 100 125Amps 0.48 0.48 0.69 1.00 1.30 1.38 2.60Watts 85 85 110 190 195 210 340Amps 0.29 0.29 0.40 0.59 0.69 0.80 1.15Watts 60 60 85 130 135 160 220Amps 0.14 0.14 0.22 0.47 0.47 0.45 0.84Watts 28 28 45 90 90 90 170Amps 0.48 0.48 0.69 1.00 1.30 1.38 2.60Watts 100 102 120 205 215 235 370Amps 0.31 0.31 0.43 0.71 0.71 0.85 1.40Watts 70 70 100 150 155 190 285Amps 0.15 0.15 0.24 0.50 0.50 0.50 1.00Watts 0.33 33 55 105 110 115 200Amps 0.35 0.35 0.69 0.91 0.91 1.38 1.82Watts 80 82 140 205 210 270 370Amps 0.26 0.26 0.44 0.57 0.58 0.82 1.10Watts 65 67 110 140 140 200 255Amps 0.16 0.17 0.25 0.34 0.35 0.45 0.65Watts 40 43 65 80 85 125 145NoteS: 1.

Vertical SeriesOptions and AccessoriesControl PackagesControls:As detailed in the table below, we offer a control for mostof the customer needs. Additional controls and devices areavailable to meet even the most demanding operating logic.Three-speed Fan ControlAll of our basic control schemes utilize a 3-speed switch tomodulate the cooling output, to maximize the percentageof latent heat removal, and to further minimize the soundlevel when maximum cooling or heating performance is notrequired.Low Voltage Control (24 V)A low voltage control is available with all of our controlschemes.Condensate Overflow SwitchThis switch shuts down the unit when the water level in thedrain pan reaches an unsafe level. Building code changes inmuch of our country now require this type of device.Service SwitchesWe offer concealed service switches for use by maintenanceand service personnel to shut off the power while workingon the unit.FusingWe offer incoming power fusing for all units as well asblower motor and control sub-fusing for units that useelectric heat. The blower motor and control sub-fusing(single power source wiring) is required when single sourcepower with electric heat is specified.Unit Mounted Series 156 Basic Wall Series 4039 Vertical Wall Series 15524 V Programmable andNon-ProgrammableDigital SeriesUnit TypeControlOptionSystem TypeCodeChangeoverTypeUnitMountedSeriesBasic andVertical WallSeries24 V Programmableand Non-Programmable Series– Manual Fan Manual A None – – –Heat Only G None Cool Only H None 2-PipeJ Manual – –Heat/CoolK Automatic Heat/Cool withL Manual – –Valve CycleAuxiliary Electric Heat M Automatic 4-PipeCool with TotalElectric HeatHeat/CoolN Manual – –P Automatic Q Manual – –R Automatic 22International Environmental Corporation • Vertical Series Fan Coil Technical Catalogwww.iec-okc.com

No water flows through thecoil with the unit off. The aquastat bypass line allows asmall amount of water to flow from the supply to thereturn piping when the control valve is closed. The straponaquastat senses whether the flowing water is beingchilled or heated and switches a contact closed to provideautomatic summer/winter changeover (ACO) for the system.When a 2-pipe cooling/heating system with optionalauxiliary electric heat is desired, an additional aquastat isrequired.Air VentSwageThree-way Motorized Control ValveBall ValveIn a three-way motorized control valve package, a divertingvalve controls water flow to the coil.
