HEAS stainless steel motorized ball valve are designed for ON-OFF control and can be piped for diverting or mixing valve applications for domestic hot water service, in central heating and/or cooling systems; or for individual room temperature control (fan coil, radiator or convector applications).
| Serial No. |
Unusual Phenomenon | Reason | Troubleshooting Method | |||||||||||||
| 1 | Open valve and close valve position are opposite | Connection error | Switch valve open line and valve close line | |||||||||||||
| 2 | Actuator does not move | Wiring error, circuit burned out | Check the power supply and wiring | |||||||||||||
| Water in the actuator or damage to the motor | ||||||||||||||||
| 3 | Cracking at the threaded connection | The connection thread does not match, the installation is not standardized or the force is too large | Replace the valve body | |||||||||||||
| 4 | The valve cannot be fully open or fully closed | The pipe is blocked by debris and the water quality is too poor | Clean up pipe debris or install pre-filter | |||||||||||||

Three lines and two controls
Voltage: 220VAC/12V/24V/110V; DC5V/12V/24V

1. The SW is connected with the blue wire, and the valve is open: When it is in place, the
internal power will be automatically cut off, and the valve will remain in the open state.
2. The SW is connected to the brown wire, and the valve is closed: When it is in place, the
internal power will be automatically cut off, and the valve will remain in the closed state.
|
1. Normally closed control mode: when the brown wire is closed, the valve opens; when it
is in place, the internal power is automatically cut off, and the valve remains in the open state.
2. Normally closed control mode: when the brown wire is disconnected, the valve is closed;
when it is in place, the internal power is automatically cut off, and the valve remains in the closed state.
3. Normally open control mode: when the brown wire is closed, the valve is closed; when it
is in place, the internal power is automatically cut off, and the valve remains in the closed state.
4. Normally open control mode: when the brown wire is disconnected, the valve opens;
when it is in place, the internal power is automatically cut off, and the valve remains in theopen state.
Note: The power-on time is not less than 2 minutes (otherwise the backup power supply
cannot be triggered to close or open the valve)

The second line is reversed
Voltage: DC5V/12V/24V

1. When the live wire and the neutral wire have power, the blue wire is closed and the
valve is opened: the internal power is automatically cut off when it is in place, and the
valve remains in the open state.
2. When the live wire and the neutral wire have electricity, the blue wire is disconnected
and the valve is closed: when it is in place, the internal power is automatically cut off, and
the valve remains in the closed state.
|
1. SW is a double switch, SW is connected with the black wire, and the valve is open: when
it is in place, the internal power will be automatically cut off, and the valve will remain in
the open state.
2. The SW is connected to the brown wire, and the valve is closed: When it is in place, the
internal power will be automatically cut off, and the valve will remain in the closed state.
