(3)The working conditions of auxiliary electric heater.
In heating mode, when compressor is working, indoor motor runs at high speed and middle speed
.if it detect T
eva
<50 for continuous 8 seconds and T
indoor
25 , electric heater will work ,if com-
pressor stop or indoor motor runs at low speed or T
eva
54 or T
indoor
28 or 10 seconds
before defrosting , the electric heater will stop.
(4)protections
a. anti cool air
when the machine starts heating and T
eva
22 , indoor motor runs at low speed, and swing
motor makes the louver at the horizontal position(in Bird line, it will swing to the maximum air
volume position), if T
eva
40 or compressor have run 2 minutes ,indoor motor and swing motor
will run at the set speed .
b. anti high temp.
In heating mode, if it detect T
eva
56 (58 can be selected), 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. stops first,15 seconds later outdoor fan
stops, Indoor motor blows 90 seconds (60 seconds can be selected) at low speed ,swing motor
makes the louver at the horizontal position(in Bird line,it will swing to the maximum air volume
postion).
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, electric heater and outdoor motor stop , indoor motor runs the same procedures as
the blowing surplus heat condition. 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 3 consecutive times within 30 minutes, the machine stops, and it must be restarted by
remote controller.
f. locked motor protection
if it detects no feedback from the PG motor for continuous 15 seconds , compressor , outdoor
motor, indoor motor and electric heater will stop, 3 minutes late, the machine will be back to its
original state, indoor motor runs as the anti cool air condition. If the motor was locked for 3 con-
secutive times, the whole machine stops and can not run again automatically.
g. defrosting conditions and procedures
In heating mode, if compressor has run 44 minutes ( in its first 6 minutes it will not detect defrost-
ing temp.) , and it has detected T
con
-4 for continuous 1 minutes , it begins to defrost , electric
heater will stop for 10 seconds ( even if electric heater is not working) , then indoor motor stops ,
reversing valve becomes inactive in another 2 seconds, another 2 seconds later, outdoor motor
stops, when T
con
10 or defrosting lasts for 10 minutes , outdoor motor and reversing valve
