Ⅰ、Working principle and composing
1、Composing
A water heater is basically composed of a compressor, an evaporator, some capillary or
expanding valves and a condenser.
2、Working principle
Heat pumps use electricity to capture heat and move it from one place to another. They
don't generate heat. As the pool pump circulates the swimming pool's water, the water
drawn from the pool passes through a filter and the heat pump heater. The heat pump
heater has a fan that draws in the outside air and directs it over the evaporator coil. Liquid
refrigerant within the evaporator coil absorbs the heat from the outside air and becomes a
gas. The warm gas in the coil then passes through the compressor. The compressor
increases the heat, creating a very hot gas that then passes through the condenser. The
condenser transfers the heat from the hot gas to the cooler pool water circulating through
the heater. The heated water then returns to the pool. The hot gas, as it flows through the
condenser coil, returns to liquid form and back to the evaporator, where the whole process
begins again.
3、Example of how a heat pump operates.

2、Safety ensured
When the unit is working, all electrophorus parts are absolutely isolated from circulating
water, thus avoiding some possible dangers such as explosion, dry heating, gas poisoning,
which may happen with a common water heater.
3、Environmentally friendly

Basic Operating Principle
Temperature controlling
The controller has 3 temperature controlling mode: Refrigeration, Heat and auto(F29).
Temperature controlling point is controlled by ¡setting temperature (F11, or press the
¡set¡ key for some time to set)¡ , ¡temperature difference(F12)¡and ¡Auto mode
temperature difference ¡.In refrigeration mode (4 way Valve is enable and follow
compressor), the controller begins to refrigerate when the temperature of the
temperature sensor is over ¡setting temperature +temperature difference¡, and it
stops refrigerating when the temperature is under ¡setting temperature -
temperature difference¡; In heat mode (Valve is disable except when defrosting), the
controller begins to heat when the temperature of the temperature sensor is under
¡setting temperature -temperature difference¡, and it stops heating when the
temperature is over ¡setting temperature +temperature difference¡ ;In auto mode,
the controller begins to refrigerate when the temperature of the temperature sensor is
over ¡setting temperature +Auto mode temperature difference¡, and it stops

9
refrigerating when the temperature is under ¡setting temperature¡, the controller
begins to heat when the temperature of the temperature sensor is under ¡setting
temperature -Auto mode temperature difference¡, and it stops heating when the
temperature is over ¡setting temperature¡.(Attention: when set F17<F12, F17=F12
admitted)
Compressor delay time
The compressor delay time is set by F21, for example, 3 minutes. The controller
contains a ¡compress or halt calculagraph ¡, and it begins to time when compressor
stops, the program first check the calculagraph before booting the compressor next
time, the program will immediately boot the compressor if the calculagraph reach 3
minutes ,if the calculagraph doesn¡t reach 3 minutes ,it will boot again when the
calculagraph reaches 3 minutes. Thus you can ensure that the boot alternation is over
3 minutes after halt, so it can prevent to breaking the compressor as a result of
frequent boot. In addition, the controller doesn¡t boot the compressor within 3 minutes
after turning on the power supply, thus the compressor can also be protected in the
state of power cut and then power on.
Auto defrosting principle
The controller will supervise the temperature of outdoor machine when heating
normally, and decide whether need to defrost according to the time of the outdoor
machine in the continuous low temperature state. In other words, the defrosting
calculagraph begins to time when the outdoor machine temperature is lower than
¡defrost start temperature¡, and turns on the defrosting when the value of time
reaches ¡defrost start time¡. The calculagraph will be cleared if the outdoor machine
temperature is higher than ¡defrost start temperature¡ when timing, and it begins to
time again when the outdoor machine temperature is lower than ¡defrost start
temperature¡ next time. In other words, the value of defrosting calculagraph shows
the continuous low temperature time of the outdoor machine.
The controller can check the defrosting effect with the temperature of outdoor
machine, if the temperature of outdoor machine goes up to the ¡defrost end
temperature¡, the controller will turn off the function of defrosting. If the defrosting time
is above ¡max defrost time¡, the controller will turn off defrosting forcibly.

10
The process above can only run in heating state, in other words, the controller will not
turn on defrosting in non-heating state.
Air defrost mode: when start defrost, the compressor stop running ,the fan continue
running; when stop defrost the compressor and fan continue running;
4 way valve defrost mode: when start defrost,the compressor and fan continue
running,the four-way valve energized;when stop defrosting the compressor and fan
continue running, the four-way valve powered off.
Water pump control
The controller can choose whether to use water pump or not (F40),0 means no water
pump function, 1 means use water pump. When water pump runs, the compressor
start up ahead of the time of F41, delaying turn off the compressor of the time of
F42.When external alarm and probation time over alarm,cut off water pump output
immediately.The compressor won¡t start up until the water pump achieve the working
time of F41.
When the machine unit stop running,the water pump follow the below request:
F43stop, F44 run,and circle.
External alarm
The controller can connect a switching value as external alarm source (Pin 4, 5), Only
when the compressor is running ,and the external alarm occurs, the controller stops,
displays the alarm code ¡A11¡. External alarm signal has 5 modes (F50):
0: without external alarm
1: always open, unlocked
2: always open, locked
3: always closed, unlocked
4: always closed, locked
¡Always open¡ means in normal state, external alarm signal is open, if closed, the
controller will give an alarm; ¡Always closed¡ is on the contrary. ¡Locked¡ means that
when external alarm signal becomes normal, the controller is still in the alarm state,
and it needs to press any key to resume.
Running in different period of time
The controller contains real time clock, and can time accurately. In ¡Econ Mode¡, the

11
controller will ensure that whether need to heat according to water temperature,
otherwise the current time is in or not in the setting period of time, if it is not in the
setting period of time, then the controller will not heat whether the water temperature
is high or low.
The controller can be set 3 heat periods of time at most, if you don¡t need some
periods of time, you can set the starting time and ending time which you don¡t need as
¡OFF¡.
In addition, if the ending time is earlier than starting time, the controller considers this
ending time is next day. For example, the period of time is ¡22:00¡to¡03:30¡, the
controller considers it as 22:00 at night to 03:30 next day.
Probation time
A probation time can be set (F87), the controller can add up the running time after
power is on, if the accumulative running time is over the probation time, the controller
will stop and display the alarm code A99, if you want to eliminate the limit of probation
time, set the F87 to ¡OFF¡, also you can use the F86 to clear the accumulative
running time, and you can try to use it again. The parameter F85 can be used to
examine the accumulative running time of the controller (hour).
Password
In order to prevent irrespective persons from changing the parameters, you can set a
password (F80), and if you have set a password, the controller will hint you to enter
the password after you press the key ¡M¡ for 5 seconds, you must enter the correct
password, and then you can set the parameters. If you don¡t need the password, you
can set F80 to ¡OFF¡. Notice that you must remember the password, and if you forget
the password, you can not enter the set state.
