AUTION
When using the "LH settings" outside the "Low Humidity Area" there is an increased risk of ice accumulation on the indoor coil or water blowing out from the indoor unit.

• The compressor frequency is controlled in function of the target evaporating temperature.
• The target evaporating temperature is controlled in function of the cooling load.

Initial minimum target Te = 2°C, but can be
changed in function of actual Te, to avoid
freeze up activation:
• Te ≤ -1°C for 20 minutes accumulated =>
Change target Te ≥ 5°C
• Te ≤ -1°C for 30 minutes accumulated =>
Change target Te ≥ 8°C
See graph 3
