according to the power configuration table, and connect it to the main power
supply.
(4)
Connect the interface of the temperature sensor delivered with
the water tank to the interface coming from the connection box of the main unit
according to the identifiers (
“TOP” for “TOP” and “BOTTOM” for “BOTTOM”) on
the line of the temperature sensor. Put the temperature sensor inside the
connection box. The line of the temperature sensor must be clamped tightly.
Check whether the temperature sensor is securely fastened. The interface
marked "CYCLE" coming from the main unit interconnects with the cycle
temperature sensor only during installation of a water return system.
(5)
Use wire clips to clamp the strong wires, and install the connection
box to the original place.
(6)
Fasten the wired controller, and connect it to with the
communications line coming from the main unit.
(7)
The communications line of the wired controller and the line of the
temperature sensor should be separated from the power cable, and the
distance between them should be greater than 20 cm. Otherwise, the unit may
not be able to communicate properly. Strong wires and weak wires need to be
separately sheathed.
(8)
For a project involving with installation of a water return pump, if the
current of the water return pump current
is less than or equal to
1 A, the water
return pump can be directly connected to the wiring board of the unit; if the
current is large, an AC contactor must be installed.
Note: This unit has the intelligent water return function. If this function is needed,
a water return pump (the size of its AC contactor depends on the pump used), pump
connection cables, and a pump temperature sensor are needed.
