LG heat pump problem

[Gary]

Well for it to overshoot by 1C were looking at about 8minutes before it goes over. FOr instance I have a setpoint of 21C when it gets to 21C the compressor speed remains the same for 8minutes till it reaches 22C then the compressor shuts down.

I'm confused. Please define each of the above "it"s.

As Gary has already pointed, you are discussing control strategy of unit with two compressors, and this one in question, is not with two compressors, therefore, this latest discussion is pretty much pointless.

Nike123 LG advised me to disregard the bit referring to the 2nd compressor as this is only used in back up on previous units when the unit needs high capacity.

The newer unit which is mine has a larger inverter compressor so they didnt require the 2nd stationary compressor.

LG say the control strategy is the same just without the 2nd compressor kicking in.

If the room temperature is the same as or higher than the set temperature and the outdoor capacity is equal to the capacity of the fan coils then the compressor will be told to run at full speed.

This doesn't make sense. It is wrong statemant or bad translation from original.

Why would compressor run in full speed when room temperature is same or higher than set temperature.
It looks like it is copy/paste from cooling control description.
I would not take this document for good explanation of control strategy.

Could you email me that document and I will then upload it to some server and link it here? Or you could done that at this page (you need to register first).

Nike can you message me your email address please.

Thank you.

All of the Its Refer to the indoor unit It = Indoor unit.

Exactly where and how are you getting your temperature measurements?
