Bank Control Bank control functionality enables a bank of output devices such as pumps, heaters or
fans to be switched On and Off under a duty / assist strategy.
If required, one of two different wear levelling schedules can be selected, Rotate or
FIFO (First In First Out).
Up to 6 stages may be configured for bank control, each of which can be assigned to a
relay or digital output. Each stage has an associated On trip value, Off trip value and
initial Output. All stages included in a wear levelling schedule must use the same
schedule type (Rotate or FIFO).
The example (overleaf) illustrates how the two modes operate to achieve wear levelling of 3
pumps in a duty / assist strategy.
