outdoor power PCB is broken. Please replace it with a
new one;
E08
EEPROM failure
Compressor stops
Cut the unit power and short-circuit JP404 port on outdoor
power PCB, repower the unit, cut power again and cancel
the short-circuit on JP404 port. If still not OK, replace the
outdoor power PCB.
F13
Room temp. sensor
failure
Unit stops
Check whether room temperature sensor is open, short-
circuit or value drifts too much. Replace it if necessary.
F14
Sanitary hot water
temp. sensor failure
Unit stops
Check whether sanitary hot water temperature sensor is
open, short-circuit or value drifts too much. Replace it if
necessary.
F15
Cooling/heating
water temp. sensor
failure
Unit keeps on
working, use "unit
water inlet
temperature" as
reference.
Check whether cooling/heating water temperature sensor
is open, short-circuit or value drifts too much. Replace it if
necessary.
F16
Unit water outlet
temp. sensor failure
Unit keeps on
working, use "unit
water inlet
temperature" as
reference.
Check whether unit water outlet temperature sensor is
open, short-circuit or value drifts too much. Replace it if
necessary.
F17
Unit water inlet
temp. sensor failure
Unit keeps on
working, use "unit
water outlet
temperature" as
reference.
Check whether unit water inlet temperature sensor is
open, short-circuit or value drifts too much. Replace it if
necessary.
F18
Indoor coil temp.
sensor failure
Unit keeps on
working, except
cooling mode.
Check whether indoor temperature sensor is open, short-
circuit or value drifts too much. Replace it if necessary.
F21
Mixture valve 1
temperature sensor
failure
Unit keep on
working, mixture
valve 1 output
fixed to 0.
Check whether TV1 temperature sensor is open, short-
circuit or value drifts too much. Replace it if necessary.
F22
Mixture valve 2
temperature sensor
failure
Unit keep on
working, mixture
valve 2 output
fixed to 0.
Check whether TV2 temperature sensor is open, short-
circuit or value drifts too much. Replace it if necessary.
F25
Communication
between operation
panel and indoor
PCB or outdoor PCB
failure
Unit stops
Communication failure between operation panel and the
indoor or outdoor PCB. Check the cable connection in
between. Check whether the last three switches on
outdoor power PCB are set to 001; whether last three
switches on indoor PCB are set to 001. Unit recovers
when communication recovers.
F27
Indoor EEPROM
failure
Unit keeps on
working
Cut the unit power, connect CN213-5 and CN213-6
together, repower the unit and then cut the power and
cancel the connect. If still not OK, replace the indoor PCB.
F28
Water pump PWM
signal feedback
failure
Unit keeps on
working
Check water pump cable connection; check power supply
to water pump; check whether water pump is broken.
F29
Mixture valve 1
failure
Unit keep on
working, mixture
valve 1 output
fixed to 0.
Check MV1 cable connection; check whether PCB output
voltage signal; check whether MV1 is broken.
F30
Mixture valve 2
failure
Unit keep on
working, mixture
valve 2 output
fixed to 0.
Check MV2 cable connection; check whether PCB output
voltage signal; check whether MV2 is broken.
