13Whenever the unit starts in Auto Start--Stop, it will run until:SIt has run for the predetermined minimum run time.SThe engine coolant temperature is above 122°F (50°C)SThe box temperature is at setpoint.The controller will not shut off the engine if the battery voltage is notsufficient to restart it. Battery voltage above approximately 13.4volts is required for shutdown. This varies depending on ambient.Look at battery voltage in data list to find out whether shutdownvoltage has been reached. If there is a “+” in front of the number,the voltage is enough to shutdown and restart. If only the numberappears, the voltage is still too low for shutdown.The controller will restart the engine if any of the following criteriahave been met:SBox temperature has changed by ¦ 11°F (¦ 6.1°C)for setpointsin the perishable range and +11° F (+6.1°C) for setpoints in thefrozen range DURING minimum off time.SBox temperature has moved away from setpoint by ¦3.6°F(2.0°C) AFTER minimum off time for setpoints in the perishablerange or +0.5°F (0.3°C) for setpoints in the frozen range.SThe battery voltage drops below 12.2 Vdc Refer to Page 19 forunit data).SThe engine coolant temperature drops below 34°F (1°C).To start the unit in manual start mode, the unit must be in continuousrun mode and the Auto/Manual Start Operation function parameterset to “MAN OP” (FN10 OFF)NOTEWhen configuration CNF11 is “ON” and setpoint is 32 to42_ F (0 to 5.5_C) the unit is locked into continuous run.The AUTO START/STOP key is disabled.NOTEAuto Start-Stop operation may be tied to the setpoint ranges forfrozen and perishable loads and the AUTO START/STOP key maybe locked out.
