Warning

With Auxiliary electrical heating, the user must install the leakage protector.


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 cable. 100 meter,

when cable’s length is up to 50m, and then 0.75mm2 cable should be used.

When cable’s length is up to 100m, and then 1.5mm2 cables should be used.


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 toanti-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.


Installation

This controller can only be installed in the place having an adequate level of protection.
► Choosing a suitable site
► Drilling the upper fixing hole ①
► Screwing on the screw
► Taking away the cover plate
► Hanging the bottom plate on the fixing hole ①
► Marking the position of bottom fixing hole ②
► Taking away the bottom plate
► Drilling the hole ②
► Re-hanging the bottom plate on screw ①
► Fixing bottom plate with screw ②
