Input/output testing is used to ensure that the
connected components are in working order.
Relay Output Testing
Selection of a setting from relay testing closes the
corresponding relay and therefore switches on the
connected component. This makes it possible to
Line no. Programming line

Warning:
During testing of an output, the heat pump is stopped,
all outputs are "off" and only the controlled output is
on.
