Default:
SINGLE-PHASE LOAD: each A.HbX refers to its respective phase.
2-PHASE LOAD: single reference setpoint A.Hb1 and OR between phases 1, 2 and
phases 3, 4.
3-PHASE LOAD: single reference setpoint A.Hb1 and OR among phases 1, 2 and 3.
+ 8 HB reverse alarm

NB: In case of 3-phase load, you can set a different value for parameter A.Hb1,
A.Hb2, A.Hb3 for each zone (ex.: to control an unbalanced 3-phase load).

Table of HB alarm functions
0 Relay, logic output: alarm active at a load current value below
set point for control output ON time.
1 Relay, logic output: alarm active at a load current value above
set point for control output OFF time.
2 Alarm active if one of functions 0 and 1 is active
(OR logic between functions 0 and 1) (*)
3 Continuous heating alarm
7 Continuous cooling alarm
(*) minimum setpoint is set at 12% of ammeter full scale
The value must exceed the cycle time of the
0 ... 999 sec
output to which the HB alarm is associated.
