Aquavar AB2S020 Controller
 |
The Aquavar AB2S020 is a variable‑speed pump controller used to maintain constant pressure in domestic or light commercial water systems. Common failures on this model include faulty pressure transducer connections, degraded motor drive circuitry (especially the MOSFET array), and burnt‑out relays due to overcurrent from improper wiring. First‑check steps: verify 115/230 V supply continuity and correct phase balance; inspect all I/O terminals for corrosion or loose contacts; review any error codes displayed on the controller’s LCD or LED panel, then test the pressure sensor output with a multimeter.[oss-gpt-20b] |
