An impulsive (2 sec. at least) closing
of contacts C1, C2, C3, permits the
passage from AUTO/MAN, from
Local/Remote Set point, recalling the
4 memorized Set points and
launching of the programmed Set
point. (see p. 16)
Universal and galvanically isolated.
2 relays are simultaneously present
for discontinuous output with single or
dual action (HEAT:COOL) and the
signal for standard continuous output
4..20mA (or 0..10Vdc) which can also
be Logic output 0/18Vdc).
