| - | ====== OpenCoral TipTop All-in-One and Top-off Controller ====== | ||
| - | |||
| - | The TipTop is the first major components in the OpenCoral system. | ||
| - | |||
| - | - Monitor water levels using up to 4 external float switches or solid-state optical sensors. | ||
| - | - Monitor temperature with 2 thermistor inputs. | ||
| - | - Control up to three pumps or other AC devices using an integrated switched AC outlet based upon user programmable sensor and time states. Uses a soft-turn on Triac based switch for minimal pump wear and no-moving-parts reliability. | ||
| - | - Report its operation, and allow override commands to be send over the [[ocnet:|OCnet]] interface. | ||
| - | - Can also be used as a dosing controller or other digital input stand-alone controller. | ||
