Note:
Maximum loading for outputs 1 and 2 is
1 amp. Circuits with a higher current
consumption must be driven by an auxiliary
relay
.
If an auxiliary relay or valve for return
temperature increase is fitted to outputs 1
and 2, parameter
PS Speed Minimum
must
be set to 100%. Additionally
, an R
F
I
suppressor (-w- 7
01 8

0) must be connected
parallel to terminal 1/
N and/or 2/
N.
T
he internal unit fuse (F1) protects only the
outputs. T
he controller cannot be
de-energised via F1.
