 ### Sequence Objects
 
-Sequences allow zones to run one at a time in a particular order with a delay in between. This is a type of watering 'playlist'.
+Sequences allow zones to run one at a time in a particular order with a delay in between. This is a type of watering 'playlist'. If a delay is specified and a pump or master valve is operated by the controller then consider the postamble setting in the _[Controller Object](#controller-objects)_. Set this to the largest delay to prevent pump on/off operations.

 ### Service `adjust_time`
 
-Adjust the run times. Calling this service will override any previous adjustment i.e. it will *not* make adjustments on adjustments. For example, if the scheduled duration is 30 minutes calling percent: 150 will make it 45 minutes then calling percent 200 will make it 60 minutes. Must have one and only one of `actual`, `percentage`, `increase`, `descrease` or `reset`.
