EcoSmart system control

EcoSmart – the Plug & Play feed console. The central system control of your rainwater harvesting system.

Dimension drawing

GRAF EcoSmart is the smart system control of your rainwater harvesting system.

The electronic control unit checks and regulates the entire operation. When the rainwater

tank level is low or becomes empty, GRAF EcoSmart automatically switches

to mains water supply until the rainwater tank is replenished, when it automatically

switches back to rainwater supply. This ensures that a minimum of mains water is

used during longer dry periods.

  • Very compact housing – only 429 x 394 x 282 mm (w x h x d)
  • No electrical parts in the tank
  • Can switch to main water at the push of a button
  • Low water consumption by supplying only when required
  • Solar capable using 24-volt technology


EcoSmart – the Plug & Play feed console

No initial pump priming

The diaphragm pump of the EcoSmart console can be safely run dry, thus

enabling immediate start-up without prior priming with water.

No floating switch

EcoSmart does without level measurement in the tank. Level measurement is

carried out via an evaluation of the diaphragm pump's power consumption.

For this reason, no float switches required in the tank.

No calibration required

The EcoSmart level measurement calibrates itself automatically. The console

can be started up immediately, regardless of the tank volume.

Tool-free plug connections

All of the connecting cables for EcoSmart feature quick connectors that can

be assembled and disassembled without the need for tools.
