FAQ
Why doesn't it start at low pressure?
(1) take down the pressure gauge line, use wire or wire to connect the "middle" and "low" terminals of the upper pool for 3 seconds, see the "upper pool full of water" indicator light on the controller is off, if off means that the upper and lower limits of pressure will start, then check the pressure gauge can be.
(2) If it does not start, and the indicator light of "water shortage in the lower pool" on the controller is often on, indicating that the "no-load setting" of the controller is not set properly, just set the "no-load setting" value down a few, and the actual value setting can be referred to page 04 of the manual.
