OPERATIONAL STATUS
Notice: Above data setting “0” is relevant to cooling mode only. All other
data, (i.e. 1 – 8) is relevant to heating.
*Remark:
Parameter 3:
0-30°C means from (-30°) to (0°)
6°C means -6°C
Parameter 9:
0: always open
1: The pool pump will start 10 seconds before compressor has started
The pool pump will stop 30 seconds after the compressor has stopped

Controller
Malfunction
Reason
Solution
PP1
Water inlet temp. sensor
failure
The sensor doesn’t detect
a reading
Switch power supply off
for 5 minutes, then switch
on again
PP2
Water outlet temp sensor
failure
The sensor is open or
short circuit
Check or change the
sensor
PP3
Coil 1 sensor failure (C)
The sensor is open or
short circuit
Check or change the
sensor
PP4
Coil 2 sensor failure (D)
The sensor is open or
short circuit
Check or change the
sensor
PP5
Ambient temperature
sensor failure (E)
The sensor is open or
short circuit
Check or change the
sensor
PP6
Temp differential between
water-in and water-out is
too high
Water flow volume too low,
water pressure difference
is too low
Check the water flow
volume/pressure
PP7
Machine in defrost mode
Ambient or inlet water
temp is very low
Wait for machine to return
to heating mode
EE1
Malfunction of system 1
System 1 protection has
failed
Switch power supply
off for 5 minutes, then
switch on again.If failure
continues, call agent
EE2
Malfunction of system 2
System 2 protection has
failed
Switch power supply
off for 5 minutes, then
switch on again. If failure
continues, call agent.
EE3
Flow switch failure
No water flow/insufficient
water in water system
Check the water flow
volume, replace water flow
stitch
EE4
Power supply connections
wrong
(for TF 100/3 and 130/3)
Wrong connections or lack
of connection
Check connection of
power supply
No display
Power supply connections
wrong
(for SF060/3, 080/3,
130/3, 200/3)
Wrong connection or lack
of connection
Check for gas leaks and
check pressure switches
EE4
Overheating of
compressor/system
(for
SF012/015/020/030/050 & 060/3)
Gas charge too low or high.
Possible system blockage
Check for gas leaks and
check pressure switches
EE5
Difference between inlet
water temperature and
outlet water temperature
too high
Water flow rate too low or
no water
Check the water flow rate
and repair
EE8
Communication failure
LED and PLC connection
failure
Check wiring
