Smartswitch Toilet Controller
Model: STS-220
The unique Deluxe Programmable Toilet Controller by SmartSwitch was designed for all electric
marine toilets with remote, fresh or salt water flushing supply via an inlet pump or water solenoid
valve. The stylish control panel provides fully automatic programmed flushing when the
Flush touch pad is pressed. It also provides independent operation of the inlet or discharge
pumps for maintenance or line clearance when the manual touch pads are used. In-built
troubleshooting features and toilet pump protection are standard.

Programming
This product has three Model Modes of operations:
Model Mode 1 = Standard Mode
Model Mode 2 = Tecma Silence (Series)
Model Mode 3 = Tecma Prestige (Series)
This product has been factory default set to Model Mode 2 (see page 3)
Factory Default: T1 = 20 seconds Model Mode = Tecma Silence (Series)
Please Note: If you have a Tecma Silent (Series) Toilet System ALWAYS choose Model Mode 2.
Should you wish to change these settings then proceed as below.
Advisory Warning: 1.5 litres per flush is the recommended minimum flush setting for discharge
lines of less than 6 feet. Dilution is the secret to efficient waste transfer, through pipes and must
be considered when programming your controller. Increase your flush volume appropriately if the
discharge line is greater than 6 feet in length.
Note – Variations in controllers may substitute the following buttons: Flush = Normal
Flush, Fill = Water Only, Empty = Empty Only.
Programmable Time Options (Actuate to ±0.1%)
Timer T1 & T2 (Water Valve/Pump) & (Extraction Motor) from 1 to 20 seconds.
Timer T3 (Water Valve/Pump) is programmable from 0 to 20 seconds.
Programming for Standard Model Mode 1
Step 1 – Placing the unit in program mode:
After wiring and applying power, hold the Fill & Empty buttons down together for 3 seconds. The
Holding Tank Full LED will give three quick flashes indicating you have entered program mode.
You may now release both buttons.
Once in program mode you can now program one of the following three times: T1 = Water
Valve/Inlet Pump, T2 = Discharge Pump or T3 = Water Valve/Inlet Pump. Step 1 will need to be
repeated for each of these delay times.
Setting T1 Water Valve/Inlet Pump Time:
After placing the unit in program mode, as in Step 1 above,press the Flush button the number of
times required for the Water Valve/Inlet Pump time (one press = 1 second, two = 2 sec’s, etc).
The Tank LED will flash once indicating a valid key press. Note: If the button is pressed 21 times
it will start back at 1 second.
Once this is done press the Empty button to store this value. The unit will flash three times
indicating the time has been set and you have left program mode.
Setting T2 Discharge Pump Time:
After placing the unit in program mode, as in Step 1 above,press the Empty button the number of
times required for the Discharge Pump time (one press = 1 second, two = 2 sec’s, etc). The Tank
LED will flash once indicating a valid key press. Note: If the button is pressed 21 times it will start
back at 1 second.
Once this is done press the Flush button to store this value. The unit will flash three times
indicating the time has been set and you have left program mode.

Setting T3 Water Valve/Inlet Pump Time:
After placing the unit in program mode, as in Step 1 above, press the Fill button the number of
times required for the Water Valve/Inlet Pump time (one press = 0 sec’s, two = 1 second, three =
2 sec’s, etc). The Tank LED will flash once indicating a valid key press. Note: If the button is
pressed 21 times it will start back at 0 seconds.
Once this is done press the Flush button to store this value. The unit will flash three times
indicating the time has been set and you have left program mode.
Programming for Tecma Silence (Series) Model Mode 2
Step 1 – Placing the unit in program mode:
After wiring and applying power, hold the Fill & Empty buttons down together for 3 seconds. The
Holding Tank Full LED will give three quick flashes indicating you have entered program mode.
You may now release both buttons.
Once in program mode you can now program one of the following two times: T1 = Water Inlet /
Discharge Pump or T3 = Water Valve/Inlet Pump. Step 1 will need to be repeated for each of
these delay times.
Tecma mode differs as the water inlet and pump discharge times work together:
The pump discharge time will be half (1/2) of the T1 = Water Inlet time (see timing chart page 4)
therefore ONLY T1 & T3 need to be programmed.
Setting T1: Water Inlet / Discharge Pump Time:
After placing the unit in program mode, as in Step 1 above,press the Flush button the number of
times required for the Water Inlet / Discharge Pump time (one press =1 second, two = 2 sec’s,
etc). The Tank LED will flash once indicating a valid key press. Note: If the button is pressed 21
times it will start back at 1 second.
Once this is done press the Empty button to store this value. The unit will flash three times
indicating the time has been set and you have left program mode.
Setting T3: Water Valve/Inlet Pump Time:
After placing the unit in program mode, as in Step 1 above, press the Fill button the number of
times required for the Water Valve/Inlet Pump time (one press = 0 sec’s, two = 1 second, three =
2 sec’s, etc). The Tank LED will flash once indicating a valid key press. Note: If the button is
pressed 21 times it will start back at 0 seconds.
Once this is done press the Flush button to store this value. The unit will flash three times
indicating the time has been set and you have left program mode.
