2.
"When temperature reached"
(•)
The normally open contact of relay K1 closes when
the ACTUAL temperature reaches 95% of the SET
temperature and remains closed until the end of the
parameterized timeout (i.e. until the end of the
cooling phase).
3.
"While cooling"
(Software revision 010 or higher)
The normally open contact of relay K1 closes at the
end of the heating phase and opens again at the
end of the cooling phase.
This configuration permits air cooling to be activated
with relay K1 during the cooling phase, for instance.
4.
"End-of-cycle impulse"
The normally open contact of relay K1 closes at the
end of the parameterized timeout (i.e. at the end of
the cooling phase) and opens again after
approximately 500ms. If a "START" signal is
activated while relay K1 is still closed, the relay
opens again immediately.
