	'''Max Remote Resets'''- If set to something other than 0, then a remote reset and start is possible. The remote reset consists of writing a "1" to register 41200 or using a remote input. As an example, if this setting is "3", then a remote reset/start can be used 3 times before a user has to be at the panel. At versions 2283 and above, if this setting is "15" then the number is unlimited.		'''Max Remote Resets'''- If set to something other than 0, then a remote reset and start is possible.

			'''Restrict remote restarts to certain faults'''- A list of faults / inputs can be selected to disallow remote restarts if the unit is down for that reason. Select the button to highlight different faults to restrict. Example: If you highlight "DI-2 SCRUBBER 1 LVL" then it is restricted. If a remote restart is attempted and the current flashing fault is "DI-2 SCRUBBER 1 LVL", the remote restart command will be ignored.

	'''Additional DI Sensors to Auto-Reset on'''- By default, if using auto restart the sensors that will allow for the auto restart are low/high suction and high/low final discharge. Additional digital inputs can be selected here that will be added to the list of inputs that allow an auto restart. This can be left blank if only suction and discharge should trigger an auto restart.

	'''Suction threshold ~~before~~ blowdown before auto restart'''- If set to something other than zero, then when a unit shuts down and an auto restart is pending, it will blow down the unit right after shutdown. The threshold acts similar to the normal blowdown threshold where the vent opens until the suction is below the given value. Note that a purge or blowdown can still happen later when the unit starts if the suction pressure reading calls for it.

'''Max Auto Resets'''- If set to something other than 0, then an auto reset/start is possible. The auto restart will happen if the conditions outlined in a previous section “Condition to allow for an auto restart” are met.

			'''Auto-Reset Delay, Minutes'''- If using auto restart, this is the time after shutdown before the unit restarts, assuming an auto restart is possible.

			'''Auto-Reset Sensor Condition'''- Optionally, a sensor condition can also be used to prevent the unit from restarting before the condition is met. ''Example'': Auto reset delay is set to 10 minutes. Auto reset sensor condition is set to "Suction > 20". In this example, if the unit shuts down on low suction it will wait for a minimum of 10 minutes AND will wait for suction to be above 20 psi before restarting.
