FLOW TIME ADJUSTMENT
Adjustment levels
The flow time is programmable on site. If necessary, the default flow time
of 30 seconds can be adjusted to any value between 5 to 2600 seconds. The
Perfect Time adjustment mechanism is composed by 3 adjustment levels for
changing the flow time. An indicator light (LED) will guide you from one level
to the other.
The following table shows the number of steps in each level, the duration at
each step and how to recognize in what adjusting level you are.

The following examples show how to manage the adjustment levels:
Example 1: You wish to adjust the flow time to 28 seconds.
At level 1 perform 3 steps of 1 second (you will get 3 seconds). Total: 3 seconds
Go to level 2 and perform 1 step of 5 seconds (you will get 5 seconds). Total: 8
seconds)
Go to level 3 and perform 1 step of 20 seconds (you will get 20 seconds). Total: 28

FLOW TIME ADJUSTMENT
How to adjust the flow time
1) Disconnect the power supply (batteries or transformer).
2) To disconnect the power supply at battery models, open the piezo cup at the
shower control body using the provided 2.5 mm Allen key.
3) Wait ten seconds.
4) Reconnect the power supply.
5) The indicator light (LED) on the back of the piezo cap will start blinking. After
a few blinks the LED will give a steady red light. Touch the designated area at
the Piezo cap when the steady red light is still on to enter into adjusting mode.
When done correctly, the light will stop blinking.
Note: If you will not press at the indicated area, the previous adjustment will
remain.
6) By touching the Piezo cap the new flow time will be programmed. In adjusting
mode level 1, each touch increases the flow time by 1 second with a maximum
of 100 seconds. You will see the LED blinking every time that a new step is
performed.
Example 2: You wish to adjust the flow time to 45 seconds.
At level 1 do not perform any step and wait until you reach level 2 (you will get 0
seconds). Total: 0 seconds
At level 2 perform 1 step of 5 seconds (you will get 5 seconds). Total: 5
seconds)
Go to level 3 and perform 2 steps of 20 seconds (you will get 40 seconds). Total:
45 seconds.
Example 3: You wish to adjust the flow time to 60 seconds.
Do not perform any step at levels 1 and 2 and wait until you reach level 3 (you
will get 0 seconds). Total: 0 seconds
At level 3 and perform 3 steps of 20 seconds (you will get 60 seconds). Total: 60
seconds.

FLOW TIME ADJUSTMENT
7) If you have reached your desired flow time at this level, stop pressing the
Piezo button. The LED will blink 2 times, 3 times , 4 times and after the 5th
time you will leave the adjusting mode. The Perfect Time is now adjusted to the
desired flow time.
8) If you need to perform steps at the adjusting level 2, wait after you see the
indicator light blinking twice and then, perform the needed quantity of steps
(with a maximum of 100 steps of 5 seconds)
9) If you do not need more levels, stop pressing. The indicator light will blink 3
times, 4 times and after 5 times you will leave the adjusting mode. The Perfect
Time is now adjusted to the desired flow time.
10) If you need to perform steps at the adjusting level 3, wait after you see
the indicator light blinking 3 times and then, perform the needed quantity of
steps.(with a maximum of 2 steps of 15 seconds)
11) To leave the adjusting mode wait until the LED blinks 4 times and then 5
times. The Perfect Time is now adjusted to the desired flow time.
Warning: In order to avoid enabling the 24 hs. hygiene flush option without
intention, do not touch the piezo cap after the LED blinks 4 times.

24 HOURS DUTY FLUSH OPTION
24 HS ANTI-LEGIONELLA / ANTI FREEZE DUTY FLUSH CYCLE OPTION
This anti-Legionella / anti freeze feature provides an automatic duty flush cycle
for 30 seconds if the shower has not been used in the previous 24 hours.
This feature is optional and is ideal for buildings such as schools where the
shower installations are often vacant for long periods. The duty flush cycle
maximizes hygiene, and prevents frozen pipes during the cold Winter months.
In order to activate this option proceed as follows:
1) Disconnect the power supply (batteries or transformer).
2) To disconnect the power supply at battery models, open the piezo cup at the
shower control body using the provided 2.5 mm Allen key.
3) Wait ten seconds.
4) Reconnect the power supply.
5) The indicator light (LED) on the back of the piezo cap will start blinking. After
a few blinks the LED will give a steady red light. Touch the designated area at
the Piezo cap when the steady red light is still on to enter into adjusting mode.
When done correctly, the light will stop blinking.
Note: If you will not press at the indicated area, the previous settings will remain.
6) To enable the automatic duty flush option you need to arrive directly to the
adjustment level 4 (please see the adjustment levels table at page 9).
Once you have entered the adjusting mode following the steps 1 to 5, wait until
the LED blinks 2 times, then 3 times and 4 times. Immediately after the LED blinks
4 times touch the piezo cup once. This will enable the hygiene flush option.
To leave the adjusting mode wait until the LED blinks 5 times. Now this option
is activated. If the shower controls will not be used for 24 hours, a single 30
seconds hygiene flush will take place.
WARNING! A safe hot water temperature control is needed
This anti-Legionella / anti freeze feature is automatic and is intended to be used
with cold or premixed water only. A thermostatic mixing valve (TMV) must be
used to provide safe hot water temperatures and prevent scalding.

BATTERY REPLACEMENT
LOW BATTERY INDICATOR
The Perfect Time shower controls have an advanced battery level management
system consisting of 2 steps. At the first step, the battery still has enough power to
open and close the solenoid valve. The battery level management system allows the
solenoid valve to be open, but will activate the LED warning indicator at the back
of the Perfect Time SH Piezo cap. The LED will blink twice when the battery level
management system has activated step 1. At this point the battery might not have
enough power to open and close the solenoid valve. The battery level management
system does not allow the solenoid valve to open. Instead of providing an opening
and closing pulse, the systems provides two closing pulses. The LED warning
indicator will blink three times when the battery level management system has
activated step 2.
