Water level controller examples
Choose the controller for the pump, starter, supply phase and tank sensors.
Three-phase example: DEV-G1 / DEV-G3
The model label and exact starter arrangement must match.
Single-phase examples
DEV-H1/H3: borewell. DEV-H2/H4: openwell or monoblock.
Check the selected model
Clock scheduling is model-specific.
H3, H4, G3 and G4 add clock timers.
H1, H2, G1 and G2 use cyclic timers.
Check wiring and settings
A running motor alone does not verify the installation.
Use the exact model diagram and a qualified electrician.
