TECHNICAL MANUAL. START-UP AND OPERATION
Basic Operating Principle
Temperature controlling
The controller has 2 temperature controlling mode: Refrigeration and Heat (F29).Temperature controlling point is controlled by "set-
ting temperature (F11, or press the "set" key for some time to "set") and "temp. difference (F12)". In refrigeration mode, the
controller begins to refrigerate when the temperature of the temperature sensor is over "setting temperature + temperature diffe-
rence", and it stops refrigerating when the temperature is under "setting temperature - temperature difference".
In heat mode, the controller begins to heat when the temperature of the temperature sensor is under "setting temperature - tem-
perature difference", and it stops heating when the temperature is over "setting temperature + temperature difference"
Compressor delay time
The compressor delay time is set by F21, for example, 3 minutes. The controller contains a "compressor 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
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 first detects the temperature of outdoor machine when it begins to heat. If it is lower than "defrost start temperatu-
re", the controller will first turn on defrosting, then turn on heating after defrosting ends. In addition, the controller will supervise
the temperature of outdoor machine when heating normally, and decide whether need to defrost according to the time of the out-
door machine in the continuous low temperature state. In other words, the defrosting calculagraph begins to time when the outdo-
or 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 will turn on the compressor and cross valve after defrosting, and the heat pump is used for defrosting.
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.
