NOT SEL
Selects the digital input for connection of a pressure switch at the pump/fan inlet. The
“normal” state is 1 (active). If the selected input switches to 0 (inactive), the action
defined by parameter 4401 INLET PROT CTRL is executed after the delay set by
parameter 4407 INLET CTRL DLY expires.
0 = NOT SEL – No digital input selected.
1 = DI1 – Pump/fan inlet pressure monitored through digital input DI1.
2 = DI2 – See selection DI1.
3 = DI3 – See selection DI1.
4 = DI4 – See selection DI1.
5 = DI5 – See selection DI1.
