KONLEN Tuya Tank Water Level Sensor Controller Monitor WIFI Automatic Flood Leak Alarm Detector Smart Life Leakage Protection

    It is a KONLEN WIFI intelligent water level controller, which can be set by Tuya smart or Smart life App to realize water level monitoring, water supplement or drainage, high and low water level remote APP push alarm notification, built-in buzzer or external siren local alarm, inquiry history record etc.

     The product is suitable for various water level control occasions, such as HVAC system, hot water process, municipal drainage, boiler, water tower, storage tank, breeding irrigation etc.

Both controller LEDs and App can display 6 water levels: 0%, 20%, 40%, 60%, 80%, 100%

Water level rising: water level < 20% electrode; App display 0%; reach to 20%, App display 20%; reach to 40%, App display 40%; reach to 60%, App display 60%；reach to 80%, App display 80%, reach to 100%, App display 100%.

Water level reducing: Water level below 100%, App display 75%; below 75%, App show 50%; below 50%, App display 25%, below 25%, App display 0%.

App main function and features:

1. Both App and six leds on controller can display current real time water level.

2. Normally relay switch CH1 connects with water pump for adding/draining water control.

In app, the No1,4,6, 7,14,15 all for relay switch CH1 control and setting.

With the setting, users can realize water level control with four working modes: add water, drain water and Time-limited adding / draining water.

3. In app, the No.2, 5, 8, 9 are for relay switch CH2 control and setting. CH2 has 4 function options (Manual, Alarm, L_On, H_Off, L_Off, H_On, so it is supplementary function options of CH1.

Choose the option" Alarm", user can connect siren or flash light for local alarm of low high water level.

Choose option "Low level_On, Hight level_Off" or "Low level_Off, Hight level_On", then water level can also control relay CH2 On/off. It can realize the second water pump to add or drain water. It can also connect heater for anti dry boiling protection. When water is lower than preset level, stop heater heating.

4. No.17 main switch is for emergency setting. When the water pump or water probe appear malfunction, users can set it Off to disable both two relays temporarily. Although two relays are disconnected, but the water level can still display normally.

Wiring Connection Examples:

Note:The feature of relay CH1/CH2 are just like a common power switch, no voltage output. The wiring connection is same as a normal switch's

Example 1:  Relay CH1 connects with water pump for adding water.

  When water level display 0% (<20%), start to add water.

                    When water level reach to 100%, stop to add water.

Relay CH2 connects with heater for anti-dry boiling protection

                  When water level ≥25%, turn on heater to heat water.

When water level display 0% (<20%), turn off heater to prevent from dry boiling.

App Setting CH1:   work mode: add,  level  on1: 0%,  level on 2: 100%

App setting CH2:  CH2 function:  L_Off, H_On (Low water level, relay CH2 Off; High water level, relay CH2 On )

                              Level On2: 25%,  Level Off2: 0%

Example 2:  

Relay CH1 connects with water pump for draining water.

When water level reach to 100%, start to drain water.

When water level ≤ 20% , stop to drain water.

Relay CH2 connects with siren or flash light for high low water level alarm or warning.

When water level  ≤ 20%,  make low level alarm,

When water ≥80%, make high level alarm.

App Setting

Set CH1:   work mode: Drain,  Level on1: 100%,  Level Off1: 20%

Set CH2:  CH2 function:  Alarm

No.10 Low level alarm: 20%

No.11 High level alarm: 80%

No.12 Remote alarm: High & Low

When water level rises to be preset high level or reduces to be the preset low level, App push alarm notification. At same time, relay CH2 connects. Siren is activated to make alarm immediately.

Example 3: Relay CH1 for adding water, CH2 for draining water

Relay CH1 connects with first water pump for adding water.

Relay CH2 connects with second water pump for draining water.

It is widely applied to public baths and other related places.

Set CH1

Work mode: Add

The preset "water level on 1" < " water level off 1"

It is "Add water" mode.

Set CH2:

CH2 function: L_Off, H_On (Low water level, relay CH2 Off; High water level, relay CH2 On ).

The preset"water level on 2 > “water level off 2".

It can realize water draining.

Relay CH1 Control Mode 1: Add water

Water level ≤ start up level, relay output 1 connects, start to add water.

Water level ≥ preset" stop level", relay output 1 disconnect, stop to add water;

Relay CH1 Control Mode 2: Draining water

Water level ≥ preset "start up level", relay ouput 1 connects, start to drain water.

Water level ≤ preset " stop level", relay output 1 disconnects, stop to drain water;

Relay CH1 control Mode 3: Time-limited adding water

Water level ≤ start up level, relay output 1 connects, starts to add water, at same time, starts the timer. Relay 1 will auto disconnect when it reaches to the preset limited running time, stop adding water.

Relay CH1 control Mode 4: Time-limited draining

Water level ≥ start up level, relay ouput 1 connects, start to drain water, at same time, starts the timer. Relay 1 will auto disconnect when it reaches to the preset limited running time, stop draining water.

High & Low water level alert

Can set to enable/disable remote alarm and buzzer alarm of low water or high water level, can choose only high water level alarm or only low water level alarm or both high low water level alarm flexibly
