1.3 MODES OF NORMAL OPERATION Following are details of the operational modes of the IntelliTec control. NOTE: The preset amounts, times, and temperatures listed below are references to actual settings on the IntelliTec control. Refer to Table 1-1 on page 7 for details on each setting. - Page 10 The "Standby Mode" maintains product quality during slow times, while minimizing reactivation time. This mode lasts for a preset time (Stb Time). Once this time has been reached without user interruption, the control moves into the "Sleep 1 Mode". Refer to Figure 1-4 for a graphical representation of the "Standby Mode".
