the machine stops caused by protection in this test mode, after release, it can not turn back to the mode
automatically again.
Thereinto indoor heat exchanger high temperature protection function is changed as follow:
a)
If T2＞58℃, compressor frequency will be descended one grade every 20 seconds. When it drops to F2, if
T2 is still higher than 58℃ and remains 3 minutes, the compressor will stop.
b)
If T2 descends to be lower than 48℃, frequency limit will be released.
c)
If T2＞60℃, the compressor will stop and not resume until T2＜48℃.
9.7.12 Turbo function in heating mode. (press the "TURBO" button on remote controller)
1)
Elevate current frequency(excluding F8) to a higher grade. If indoor fan is in low speed or pause caused by
defrosting or anti-cold-wind function, frequency of compressor will not be elevated one grade until these limit
has been released.
2)
Indoor fan changes to turbo speed and anti-cold-wind function is valid.
3)
In turbo mode, general protection, maximum frequency limit, indoor heat exchanger high temperature
protection is valid.
4)
After running for 30 minutes the machine will turn back to previous setting mode.
5)
In non-turbo mode, press "TURBO" button on controller will switch current mode to turbo mode, if user press
this button again, the machine will turn back to previous setting mode.
6)
In turbo mode, turning off the machine or switching running mode will make the machine quit turbo mode.
9.8 Auto mode function
9.8.1 This mode can be chosen with remote controller and the setting temperature can be changed between 17~30℃.
In auto mode, the machine will choose cooling, heating or fan-only mode according to ΔT(ΔT =T1-Ts).
9.8.2 Indoor fan will choose auto speed of relevant mode.
9.8.3 The louver action is the same as that in relevant mode.
9.8.4 If the machine switches mode between heating and cooling, compressor will keep stopping for 15 minutes and
then rechoose mode according to ΔT.
9.8.5 If the setting temperature is modified, the machine will rechoose running function.
9.8.6 Turbo function in this mode is the same as that in relevant mode.
9.9 Forced operation function
9.9.1 Forced cooling and auto function can carry out with a touch button. In these two modes, the machine can be
changed by remote controller to any other mode at any moment.
9.9.2 When the machine is off, pressing the touch button will carry the machine to forced auto mode, after this, if
pressing the button once again within 5 seconds, the machine will turn into forced cooling mode. In forced auto,
forced cooling or any other operation mode, pressing touch button will turn off the machine. In forced operaton,
remote control is available.
9.9.3 In forced operation mode, all general protections is available.
9.9.5 In forced cooling mode, compressor frequency is fixed at F2, indoor fan is at freeze grade, anti-frozen, outdoor
unit current protection and maximum start and running frequency limit caused by outdoor temperature are valid.
After running for 30 minutes.the machine will turn to normal auto mode which setting temperature is 24℃.
