(5) Anti-cold air function in heating mode
After entering heating mode, or last defrosting is over, the compressor will start up, if Tg
<
28
℃
(HW_
D2), indoor motor will stop; if 38
℃
(HW_D1)>Tg≥28
℃
(HW_D2), indoor motor will run at low speed;
if Tg≥38
℃
(HW_D1) or the compressor has run for over 4 minutes, indoor motor will run at the set
speed; once the motor has started up, it will not stop because of Tg reduction.
(6) Blowing remaining heat function
In heating mode, the thermostat is OFF, the compressor stops, indoor motor will run at low speed
until Tg
<
28
℃
(HW_D3) and has run for 50 seconds at least. If Tg always over 28
℃
(HW_D3),
compressor will stop after running for at max. 3 minutes.
(7) Note: in heating mode, “the compressor stops----indoor motor delays to stop” adjust if the pipe
blows remaining heat; “the compressor startup----indoor motor delays to start up” adjust if the
pipe is anti-cold air; in other conditions, the compressor and the indoor motor are allowable not to
be in company. In cooling mode, the motor will run according to the control, not together with the
compressor.
(8) Defrosting function in heating mode
In defrosting and when the compressor resumes to running for 3 minutes after defrosting is over, the
unit will not adjust the sensor failure.
Manual defrost:
In heating mode, the set temperature 30
℃
and in high speed, in 5 seconds, press SLEEP button 6
times continuously, then the buzzer will sound 3 times, you can enter the manual defrosting. Send
manual defrost to outdoor unit, the indoor unit will control accordingly after received the outdoor
defrost signal, the procedure is as the same as the auto defrost; the quit is controlled by outdoor
unit.
Auto defrosts:
For the unit with outdoor PCB, please refer to the outdoor control functions.
(9) Auxiliary electric heating function (valid in heating mode or heating state in AUTO mode) Enter
condition:
1) ΔT>1
2) Thermostat ON and running for 1 minute
3) Tr<25
℃
4) Indoor motor running
5) Electric heating function start signal available
6) The system working in heating mode or in heating state of AUTO mode
If the above conditions can all be met, the electric heating function will work.
Quit condition:
1) ΔT≤1
2) Thermostat OFF
3) Tr>26
℃
4) Indoor motor stops
5) Electric heating function start signal not available.
6) The system in non-heating operation.
7) Coil pipe temp.>52
℃
If one of the above conditions can be met, the electric heater will stop.
