Panel Control box Description:
Smart Toilet Control (STC) is a controller for flushing toilet to optimize water use without compromising the quality of flush.
Control consists of a controller, panel and 7’ of cable.
STC is designed to automatically start a  flushing cycle if NORMAL FLUSH or WATER SAVER buttons are pressed.
WATER ONLY button brings inlet water to  the bowl when pressed and EMPTY ONLY button evacuates the bowl. Both water only and empty button have a time limit of eight seconds.
Flush timing of initial fill, discharge and final fill are fully programmable from the panel.
If wired, the panel also shows holding tank full status. When holding tank full LED is lit, normal and water saver button are disabled. Water only and empty button continue to function.
Control is reverse polarity protected. In case of reverse polarity motors and solenoid will activate as soon as power is connected. After reverse polarity is corrected (within 10 minutes), unit will work as normal.

OPERATION

Smart Toilet Control:
IMPORTANT: Discharge and Inlet Pump / Valve MUST BE wired for proper operation and programming.

1. EMPTY ONLY
   Press to evacuate the bowl. Discharge pump runs as long as this button is held with an eight second limit. if holding tank full LED is on this button still works.

2. WATER ONLY
   Press to add water in the bowl. Inlet water solenoid/pump runs as long as button is pressed with an eight second limit. After limit is reached. this button is disabled to prevent overflow of the bowl. To enable again, EMPTY ONLY button must be pressed. If Holding Tank Full LED is on, this button still works.

3. NORMAL FLUSH
   Press to start timed flushing cycle. If Holding Tank Full LED is on, this button is disabled. There are three cycles of inlet and discharge. First cycle removes most of the waste. Second cycle removes remaining waste if any left after first cycle. Third cycle clears all discharge housing and lines with clean water. Last fill is to retain water in the bowl for next use. This button is disabled if Holding Tank Full LED is on.

4. WATER SAVER
   Press to start water saver cycle. If Holding Tank Full LED is on, this button does not work. This cycle has only one cycle of inlet and discharge to clear liquid waste. Last fill is to retain water in the bowl for next use. This button is disabled if Holding Tank Full LED is on.
   NOTE: Holding Tank Full light will only illuminate if the tank sensor has been added to the control.

Programming of Toilet Flush Control
The Raritan Smart Toilet Control offers two different flush modes to choose from:
Senuential Flush. In this mode, the toilet will add water and discharge waste separately. This fill/empty cycle will repeat once in WATER SAVER and throe times during the NORMAL FLUSH cycle. At the end of this sequence cycle, a short pause will be followed by a final fill to leave water remaining in the bowl.
This mode is designed to provide the most efficient flush possible while using the least amount of water. It keeps the discharge pump flooded while providing powerful suction to remove waste from the bowl.
NOTE: All toilets as shipped from factory are set to the Sequential mode.
Continuous Flush : In this mode, the toilet will add water to wet the bowl first and then follow with the inlet and discharge motors flushing together for the remainder of the cycle. At the end of this continuous cycle, a short pause will be followed by a final fill to leave water in the bowl. This mode may be more suitable for installations in which a continuous flow of water is desired and water use is not as great a concern.
Changing flush mode from Sequential to Continuous and vise versa:

1. Hold the WATER ONLY and EMPTY ONLY buttons down together for three seconds. The Holding Tank Full LED will flash THREE times indicating you have entered program mode.
2. Push the WATER SAVER button once.
3. Push the EMPTY ONLY button. Flush mode will switch from Sequential to Continuous or vice versa.
   The Holding Tank Full LED will flash THREE times indication you have left program mode.

Programming your Smart Toilet Control:
The Raritan Smart Toilet Control is factory set to work in most installations and no programming is required. The following instructions can be used to modify timings if desired:
All flush cycles have an initial fill time (TI), Discharge/ Empty time (T2) and water retention fill time (T3).
Factory default settings for the
NORMAL FLUSH are as follows:
Sequential mode: T1= 3 sec, T2= 3 sec, T3= 2 sec
Continuous mode: T1= 3 sec, T2= 12 sec, T3= 2 sec
Step 1 – Entering program mode:
Hold the WATER ONLY and EMPTY ONLY buttons down together for 3 seconds. The Holding Tank Full LED will flash THREE times indicating you have entered program mode release both button.
Setting TI initial fill time:
After entering program mode (Step I above) push the NORMAL FLUSH button once. Continue to press the NORMAL FLUSH button equivalent to the number seconds you wish water to enter the bowl: (one push— I second, 2 pushes— 2 seconds, etc.). The Tank LED will flash after each valid key push. The maximum inlet time is 20 seconds. When finished, push the EMPTY ONLY button to store this value and exit. The Holding Tank Full LED will flash THREE times indicating you have left program mode.
Setting T2 Discharge Pump Time:
After entering program mode (Step I above) push the EMPTY ONLY . button once. Continue to press EMPTY ONLY button equivalent to the number of seconds you wish water to exit the bowl: (one push— I second, 2 pushes— 2 seconds, etc.). The Tank LED will flash after each valid key push. The maximum empty time is 20 seconds. When finished, push the NORMAL FLUSH button to store this value and exit. The Holding Tank Full LED will flash THREE times indicating you have left program mode.
NOTE: When in Continuous mode, the WATER SAVER empty time will operate at half of the NORMAL FLUSH time setting (Wall switch models only).
Setting T3 Water Retention Fill Time:
After placing the unit in program mode (step I) push the WATER ONLY  button once. Continue to press the WATER ONLY  button as follows to leave water standing in the bowl: (I push— ZERO seconds, 2 pushes— 2 seconds, 3 pushes— 3 seconds, etc).
The Tank LED will flash once indicating a valid key push. The maximum water retention time is 10 seconds. When finished, push the NORMAL FLUSH b button to store this value and exit. The Holding Tank Full LED will flash THREE times indication you have left program mode.
Disabling the WATER ONLY and EMPTY ONLY buttons (Wall switch model only):
When in the factory default mode, both the WATER ONLY and EMPTY ONLY buttons will only operate for maximum of eight seconds. The procedure below will disable these buttons completely if desired:

1. Hold the WATER ONLY and EMPTY ONLY buttons down together for 3 seconds. The Holding Tank Full LED will flash THREE times indicating you have entered program mode.
2. Push the WATER SAVER ****button. This will disable/enable this feature.
3. Push the WATER ONLY ****button. The Holding Tank Full LED will flash THREE times indicating you have left program mode.
   Repeat steps I to 3 to re-enable these buttons.

Extending pause for water retention:
Some installations may require adjustment if water siphons out of the bowl after the flush cycle is complete. This adjustment will increase the pause time between the final empty time and the water retention fill time. The factory set pause is for 2 seconds, but can be changed to 10 seconds by fol- lowing the procedure below:

1. Hold the WATER ONLY and EMPTY ONLY ****buttons down together for 3 seconds. The Holding Tank Full LED will flash THREE times indicating you have entered program mode.
2. Push the WATER SAVER button. This will disable/enable the 10 second pause mode.
3. Push the WATER SAVER button again to exit program mode. The Holding Tank Full LED will flash THREE times indicating you have left program mode.

Repeat steps I to 3 to re-enable change between pause modes.
