Gas heater control valve does not work

1. softener or Gas Control Valve no longer a student), the controller can not control the rotation of the motor A, the gas heater control valve power interruption: damage to equipment failure or power adapter (no display screen). If no power but no display screen, can be used the same type of power supply for testing; now Run the new Propane Control Valve mainly uses two types of power adapters, output voltage and current are DC12V, 1500mA and DC24V, 1500mA. B, motor and motherboard cable shorted. Water immersion or valve leakage control panel, this phenomenon can occur when such installation. C, the motherboard is damaged and can not control the rotation of the motor. D, motor damage. Mainly caused by patio heater control valve leakage. 2), the regeneration time setting unreasonable time or flow regeneration program shows yet to come, but the actual water hardness has been exceeded. A, time type, the regeneration time is set incorrectly, exceed the maximum of water softener system cycle. If this should be renewable once for two days, is set to 20 days renewable once. B, flow type, the total flow is not cut down or decreasing slower than the actual speed, the meter is damaged, no instantaneous flow. For two main reasons: ① suck iron impeller is stuck or foreign body material, can not be rotated. ② meter meter cord is damaged or loose with the motherboard socket. ③ control board failure. 3), the motor can not control spool rotation.
