ELECTRIC HEATING Electric Resistance Heating Electric heaters are available on IEC Horizontal Series fan coil units for the following applications. Total Electric Heat Total electric heat eliminates the requirement for a boiler. Heating and/or cooling may be available on an individual basis throughout the year. Two-pipe chilled water is used for cooling; and the electric heater is used for heating. Individual room controls can be supplied for either manual or automatic changeover. Auxiliary Electric Heat Auxiliary electric heat is ideal for tempering room air between seasons and during the cooling season when chilled water is being circulated. Individual room controls are supplied to provide electric heat only when chilled water is being circulated. During regular heating season, heating is provided by hot water being circulated in the system. Construction The heater coils of high-grade resistance wire are supported by ceramic insulators on plated steel brackets. These heat elements are suspended directly in front of the fan outlet between the blower and the coil. High limit thermal cutouts protect the heater in the event of air failure. There are many special applications and control sequences for electric heat. For special applications, please consult the factory.

STANDARD FEATURES & OPTIONS, Cont d. As detailed in the table on page 27, we offer a control for most of the customer needs. Additional controls and devices are available to meet even the most demanding operating logic. Three-speed Fan Control All of our basic control schemes utilize a 2- or 3-speed switch to modulate the cooling output, to maximize the percentage of latent heat removal, and to further minimize the sound level when maximum cooling or heating performance is not required. Low Voltage Control (24 V) A low voltage control is available with all of our control schemes. Condensate High Level Switch This switch shuts down the unit when the water level in the drain pan reaches an unsafe level. Building code changes in much of the country now require this type of device. Service Switches We offer concealed service switches for use by maintenance and service personnel to shut off the power while working on the unit. Fusing We offer incoming power fusing for all units as well as blower motor and control sub-fusing for units that use electric heat. The blower motor and control sub-fusing (single power source wiring) is required when single source power with electric heat is specified.

PIPING PACKAGES (TYPICAL) Two-way Motorized Control Valve In a two-way motorized control valve package, the motor drives the valve open, and a spring returns the valve to a normally closed position. No water flows with the unit off. The standard supply connection from the coil will accept a swaged copper fitting for field brazing. As an option, this connection may be factory furnished with a union. When a swage is necessary, it becomes part of the valve package. The isolation, or ball, valve in the return piping is shipped loose for field installation. Air Vent Three-way Motorized Control Valve In a three-way motorized control valve package, a diverting valve controls water flow to the coil. When the unit is off, water bypasses the coil and flows directly to the system return. A balancing valve may be specified in the bypass line to permit equal flow balancing. Air Vent Coil R Swage 3-way Valve Ball Valve Optional Balance Valve R Coil R S Swage 2-way Valve Ball Valve (Ships Separate) Ball Valve Two-way Motorized Control Valve with Changeover In a two-way motorized changeover control valve package, the motor drives the valve open, and a spring returns the valve to a normally closed position. No water flows through the coil with the unit off. The aquastat bypass line allows a small amount of water to flow from the supply to the return piping when the control valve is closed. The strapon aquastat senses whether the flowing water is cold or hot and switches a contact closed to provide automatic summer/winter changeover (ACO) for the system. R S S Swage A Aquastat Ball Valve NOTES:. Please note that project specifications for system pressure, pressure drop limitations and flow rate should be checked prior to selecting specific components or the valve package size. 2. The supply and return piping connections of the factory-provided valve package are either swaged for field brazing (standard) or union fitted (optional) for connection to the coil. 3. Consult IEC s Valve Packages and Piping Components manual or your local representative for detailed piping and valve application information. Factoryprovided valve packages are assembled, brazed, wired electrically and dry-fit to the coil connections before shipping. Field brazing to the coil completes the installation. Some applications dictate shipping isolation valves loose. S Air Vent R Swage Ball Valve R Coil S Swage 2-way Valve A Aquastat Aquastat Bleed Bypass Line Ball Valve S 3
