Heat sensor:
Typically used with a digital output that has the function "Heat control". The input typically
has a heat sensor fitted which gives a 0-10V output signal. The input is scaled according to what 0V and 10V
correspond to. This defines a low limit at which the heat control must be activated and a high limit at which
heat control is deactivated.
Valve opened:
Used with a digital output that has the function "Open valve", the function is used with
another set of DI/DO, where you can open and close a valve that stops the supply to the pump well,
whereby the inlet pipes can be used as reservoirs in case of increased inflow/rain event etc.
Valve closed:
Used in conjunction with a digital output that has the "Close valve" function. Read the
description above.
General stop:
Used as a general stop function. If the digital goes high it stops the pumps. Can be used in
case of

dry running
”
of pumps, where a mechanical stop is activated and stops the pumps.
