The controller will stop if the
accumulative time is over
probation time, and show the
alarm code “A99”.
OFF means no probation
time
This function can attract all relays in turn, and please don’t use it
when the controller is running!
'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 refrigerating when the temperature is
under “setting temperature”, the controller begins to heat when the temperature of the temperature
