1 LEAD/LA CONTOLLE INSTALLATION INSTUCTIONS

2 INTODUCTION The from Specified Controls is a versatile, AC powered lead/lag controller offering true dual stage control to balance the operating run time between HVAC equipment as well as other redundant devices. The controller has dedicated terminals for AC power, 2 inputs and 2 outputs. LEDs provide visual indication for power and output status. SEQUENCE OF OPEATION When 24 Volt power is first applied to the AC terminals 7and 8 on the, and output contacts remain open. When 24 Volts is applied to input terminal 1, output contacts go closed and contacts remain open. When 24 Volts is removed from terminal 1 for at least 10 seconds, output contacts open. When 24 Volts is reapplied to terminal 1, output contacts remain open and output contacts go closed. The lead/lag sequence is reversed every time 24 Volts is removed from terminal 1 for more than 10 seconds and then reapplied. In a dual stage application, 24 Volts applied to terminal 2 will close the lag output contacts. As long as 24 Volts is maintained on terminal 1, the lag output can be cycled on and off. The Lead/Lag Controller must be powered from the same 24 Volts as control circuit or a relay will be required. WIIN DIAAMS The wiring diagrams illustrated in this installation manual represent a sampling of the many ways the can be applied for lead/lag control. The is an operating controller only and depending on the application, it is the responsibility of the installer to verify that the complies with all electrical and/or plumbing codes.
