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)
Model Mode 4 = European Mode
This product has been factory default set to Model Mode 2 (see page 4)
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.
This manual applies to units manufactured after 01/08/2012

Programming for Standard Model Mode 1
Step 1 –Placing the unit in program mode:
After wiring and applying power, hold the Water Only & Empty Only 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 timers: 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 Normal 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 Only 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 Only
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 Normal 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 Water Only 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 Normal 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 Water Only & Empty Only 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 6) 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 Normal 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 Only 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 Water Only 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 Normal 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 Prestige (Series) Model Mode 3
There is no programming required for this mode as the times are fixed (see timing chart
page 6).
