Configuring hysteresis control via Equation smart rule

The example below shows how to configure filling of retention tank based on measurement of minimum and maximum water level.

doc_tap_exlevel;

Inputs:

• Reed contact for min level (Variable name: St)
• Reed contact for max level (Variable name: St1)

Output:

• Digital output for control of valve or pump (Name: Valve)
• doc_tap_ InpOutp;

Configuring Equation smart rule

doc_tap_ConfEqua;

Equation

(LastState AND !St1) OR (!LastState AND !St)

Action

If result is TRUE: Valve ... Turn On

If result is FALSE: Valve ... Turn Off

Duration

Minimum duration ... 0:05:00 minutes
