The model and specifi
-
cations of the solenoid
valve are not suitable for
the transformer.
2) The solenoid valve is
broken.

TC terminal has no 220 V
output.
1) Check whether the model and
specifications of the solenoid
valve are suitable for the trans-
former (AC 110/220 V).
2) Replace the solenoid valve.
3) Contact the agent or Inovance for

Err96
Phase sequence
abnormal
Three-phase input sequence
abnormal (R, S, T)
Exchange any two of the phase se-
quences.
Err97
Output phase loss
of mains frequency
cooling blower
1) The motor wiring is incor-
rect.
2) The motor cooling blower
is damaged.
3) The fuse is loose or dam-
aged.
1) Wire the motor properly.

Err98
Low pump pres-
sure
1) The water pump function
is not provided, and the
DI terminal is allocated
with function 59.
2) The water pump function
is provided, and the DI
terminal is allocated with
function 59.
1) Allocate the DI terminal with func-
tion 0.
2) If the water pump is abnormal,
repair or replace it.
