Use for 08/0 v. NOTES:. Disconnect power before servicing.. See name plate for correct voltage. Use 75 C minimum copper conductors only. Unit terminals are not designed to accept any other wiring.. Motor(s) are thermally protected. Units with motors are wired parallel.. Provide disconnect means and overcurrent protection as required. 5. Motor shown for 0/77 v operation, for 08/0 v motor common is or. 6. Valve optional, factory-supplied or field-supplied with NEC class wiring. Do not exceed thermostat rating. 7. To ensure proper fan interlock and sequencing, external controller must energize heater stages in numerical order shown and deenergize stages in reverse order (first on, last off). 8. All contractor wiring must conform to national and local electrical codes.

3 OPERATION Manual Fan Control The standard fan-speed switch is furnished unit-mounted and wired on all vertical cabinet units. On all vertical furred-in units and all horizontal units, the switch is shipped separately on a decorative wall plate for field mounting and wiring. The standard switch has, IUM, H and OFF positions plus an auxiliary contact to energize thermostats, valves, dampers, etc. Thermostatic Fan Control, -Pipe Systems The thermostat cycles the fan on and off from any selected speed setting to maintain selected room temperature. Controls can be wired for heating-only, cooling-only or for heating/ cooling with the addition of an automatic changeover device that senses water temperature and changes the action of the thermostat as required. Thermostatic Fan Control, -Pipe Systems with Safety Cycle This control is used for high humidity situations in which condensate problems can occur if fan is turned off while chilled water is still running through the coil. The wiring provides fan cycling from H to on the cooling cycle and from to OFF on the heating cycle. An ON-OFF toggle switch replaces the standard -speed fan switch. The toggle switch can be concealed to ensure that the unit runs on low speed when cooling. This action greatly reduces the chance of condensation problems that exist with other standard fan cycling controls. Thermostatic Electric Valve Control, -Pipe A thermostatically controlled -position valve provides superior control to fan cycling. With this control, the fan runs continuously unless it is manually switched to the OFF position. The fan must be on before the valve can be opened to supply water to the coil. This system can be used for normal -pipe changeover systems and can also be furnished for cooling-only or heatingonly applications by omitting the changeover and specifying which application is intended. Thermostatic -Pipe Auxiliary Electric Heat with Valve Control This system, also called Twilight or Intermediate Season electric heat, goes a long way towards solving the spring and fall control problems of -pipe systems. Chilled water can be available late into the fall. It may also be turned on early in the spring and still provide heat to all units when required. In winter, the system is switched over to hot water and requires two auto changeover devices (aquastats). One device controls the switching of the thermostat, the other device locks out the electric heater when hot water is in the coil. With this system, the fan runs continuously unless manually switched to the OFF position. Fan must be on before thermostat can send signal to open chilled water valve or turn on electric heater. Two control methods are available:. Use of a standard automatic changeover thermostat with a deadband between heating and cooling.. Use of a manual changeover thermostat. Only one changeover is required with this method. A -way or -way electric valve must be included with this system. Thermostat -Pipe Total Electric Heat with Valve Control With this system, the complete heating requirement for the space is provided by the electric heater; the water system is never changed over for heating. It is therefore possible, just as with -pipe systems, to have heating or cooling at any time of the year. The fan runs continuously unless it is manually switched to the OFF position. Fan must be on before thermostat can send signal to open chilled water valve or turn on electric heater. Normally, an automatic changeover thermostat with a deadband between heating and cooling is used, but a manual changeover thermostat is also suitable. A -way or -way valve must also be used so that the chilled water is off whenever the heater is on. No changeover device to sense water temperature is necessary. Thermostatic Valve Control, -Pipe The -pipe system provides the ultimate in economy and room temperature control. Both hot water and chilled water are available at any time. Normally an automatic changeover thermostat is used, but a manual changeover thermostat is also suitable. Two -way valves, two -way valves, or one -way plus one -way valve must be selected. An automatic changeover device to sense water temperature is not required. With this system, the fan runs continuously unless it is manually switched to the OFF position. The fan must be on before thermostat can send a signal to open the chilled water or hot water valve.
