Block “Multifunctional relay”
141 Function of multi-
functional relay
0
(0…7)
.........................
0 = no function
1 = outside temperature switch
(set operating lines
143…145)
2 = ON / OFF according to time
switch (select time switch
on operating line 146)
3 = relay ENERGIZED in case
of fault
4 = relay ENERGIZED during
occupancy time
5 = relay ENERGIZED during
occupancy time incl. optimi-
zations
6 = relay ENERGIZED when
there is a demand for heat
7 = manually ON / OFF accord-
ing to operating line 142
If operating line 125 is not 0,
this operating line cannot be set
142 Manually ON / OFF 0
(0 / 1)
