2.4 Advice regarding the installation of temperature sensors

T1, T2 sensor cables carry low voltage, and to avoid inductive effects, must

not be laid close to 230 Volt or 400 Volt cables (minimum separation of

100mm).

T1, T2 sensor cables may be extended to a maximum length of ca. 100

meter, when cable’s length is up to 50m, and then 0.75mm2cable should

be used. When cable’s length is up to 100m, and then 1.5mm2cables

should be used.

2.5 Installation of solenoid valve

Flushing pipe and cleaning pipe before mounting the solenoid valve

If water is provided by water tower, to avoid no water filling or water flow

rate is too low at solenoid valve, please select the solenoid valve which

pressure is matched to the hydraulic pressure got from water tower.

Check whether the required voltage labelled on the type plate of solenoid

valve is same to the voltage of power output of controller, check whether

the filter of solenoid valve is completed, whether the body of valve has no

damage. And during installation please pay attention to the water flow and

return of solenoid valve, side with filter is the water input, water flow

direction and arrow signal on the body of solenoid valve should be aligned

in same direction.

Solenoid valve should be

indoor installed at the place

where is easy for maintenance

or at the area where no more

connected loss happened. To

keep a long lifetime of solenoid

valve, please pay attention to

anti-frost, sun protection and prevent broken damage from freezing or

aging of body of solenoid valve.

It is prohibited to use a wrench worked on the coil wire and plastic parts, to

ensure no damaged during installation and no torsion effect positioned on

the solenoid valve, it is not allowed to install valve compulsively when tow

connectors are not aligned.

Two-cores wire is used for connection with solenoid valve, if wire needs to

be lengthened, please select cable of 1.0mm2.

To easy clean the filter, water inlet pipe connected to the solenoid valve

should be a kind of soft pipe or pipe is easily dismounted.

Note: one-way check valve integrated into the solenoid valve, so no

one-way valve needs to be installed.

2.6 Installation of sensor of temperature and water level

Sensor of water temperature and water level is inserted into tank from the

overflow connector.

Fasten sensor with the mutter of

sensor.

3-cores wire of sensor connected to the input port of controller

- Port 1: connect red wire (+12V)

- Port 2: connect white wire (COM)

- Port 3: connect black wire (GND)

Note：

1).Depending on the way of difference installation, we provide three different

sensors, and the customer chooses one of them as needed. If the customer

does not specify anything, we will follow the factory default configuration.

a).”Side mounted sensor”

(factory default configuration) see

the picture 1

b).”Top mounted sensor”

(need to be specified in order) see the

picture2

c).”Bottom mounted sensor”

(Need to be specified in order) refer the details of Paragraph 2.7

2). To avoid the measuring error or damage the sensor, sensor of

temperature and water level must not touch or close to the e-heater tube

2.7 Bottom installation of sensor of temperature and water level

There are 2 installation ways for positioning the sensor of temperature and

water level on the bottom part of tank: one way is inserting sensor from hole of

collector, the other is inserting sensor from bottom of tank. Diameter of

installation hole is 47mm.

Note: this diagram is only for reference.

4. Functions operation

Before switching-on the power, please connect sensor of temperature and

water level, water filling solenoid valve to the input port of controller, connect

electrical heater to the output port of controller. And then switching-on power,

the controller runs an initialization phase for 5 seconds, then controller runs a

commissioning menu, it leads the user through the most important adjustment

channels needed for operating the system.
