eva
42 , telecontrol motor runs at low
speed. if T
eva
43 , indoor motor and swing motor will run at the set speed .
b .anti high temp.
In heating mode, if it detect T
eva
58 , outdoor motor will stop( in this period it will not detect
the defrosting temp.). if T
eva
52 , outdoor motor will be back running (it will not detect defrosting
temp. in the first 5 seconds).
c. blowing surplus heat
In heating mode, when set temp is reached ,comp. outdoor fan stops, Indoor motor blows 60
seconds (60 seconds can be selected) at the set speed.
d. Compressor’s protection is same with the one in cooling mode.
e. Overload protection
If it detects that the system current surpassed the designed 13 A for continuous 3 seconds,
compressor, outdoor motor stop, after 15seconds delay indoor motor stop. After 3 minutes and
current no more than 13 A, the machine will be back to its original state, indoor motor runs as the
anti cool air condition. If it detects overloading state for 6 consecutive times, the machine stops,
and it must be restarted by remote controller.
f. defrosting conditions and procedures
In heating mode, if compressor has run 45 minutes ( in its first 6 minutes it will not detect defrost-
ing temp.) , and it has detected T
con
-8 for continuous 1 minutes , it begins to defrost , after 15
seconds indoor motor stops , reversing valve, outdoor motor stops, when T
con
10 or defrosting
lasts for 10 minutes , outdoor motor and reversing valve becomes active , indoor motor will run as
the anti cool air condition, then it cycles again, recalculates the compressor’s running time again.
(In this period , if any protection works ,and after the machine is back to work , it will re-start defrost-
ing state. it will not detect outdoor tube temp when compressor’s in its first 6 minutes running )
g.noise lowering protection
When you use RUN/STOP button to switch off the machine, reversing valve will become inac-
tive in 2 minutes.
