If | If proper conditions are met, the pool is automatically filled when a low threshold is met via the surge tank water level sensor. | ||
Auto fill is enabled by default. This is indicated by a periodic <tt>AutoFill Enabled</tt> LCD notification. It may start during any state other than <b>Backwash</b> and the waiting to restart states following a "Critical Level Low (LL)" result. When in the one of those states, auto fill is paused and <tt>AutoFill Paused</tt> is periodically shown on the LCD. | |||
When auto fill is enabled, the "Level Low (L)" and "Level High (H)" results of the surge tank level are not fault/warning conditions; they becomes strictly thresholds at which auto fill starts/stops. | |||
Auto fill operates until the high level is met or auto fill is disabled. Auto fill operates for at least 2 minutes. If the high level threshold is not met after 4 hours, a timeout occurs. A timeout prevents auto fill for 12 hours in an effort to prevent over-filling the pool in the event of a sensor failure. This is indicated by a periodic <tt>Fill: TO (12 hr)</tt> LCD notification. If the high threshold is met within the 4 hour period, a minimum off time (MOT) prevents auto fill for 4 hours to prevent frequent cycling. This is indicated by a periodic <tt>Fill: MOT (4 hr)</tt> LCD notification. In theory, 3-5 cycles of auto fill may complete in a day, though thresholds should be set to keep this to 2 or less. | |||
