Temperature Range Setting - LG ARNH10GK2A2 Installation Manual

Temperature Range Setting

• Function Code 11 : Setting Air Temperature in Cooling Mode
Determine cooling setting temperature range when air temperature is selected as setting temperature.
NOTICE
Only available when remote air temperature sensor is connected.
• Accessory PQRSTA0 should be installed.
• Also, Function Code 03 should be set properly.
• Function Code 12 : Setting Leaving Water Temperature in Cooling Mode
Determine cooling setting temperature range when leaving water temperature is selected as setting temperature.
NOTICE
Water condensation on the floor
• While the unit operates in cooling mode it is very important to keep leaving water temperature
higher than 16°C(60°F). Otherwise, dew condensation can occur on the floor.
• If floor is in humid environment, do not set leaving water temperature below 18°C(64°F).
NOTICE
Water condensation on the radiator
• While the unit operates in cooling mode cold water may not flow to the radiator. If cold water
enters to the radiator, dew generation on the surface of the radiator can occur.
• Function Code 13 : Setting Air Temperature in Heating Mode
Determine heating setting temperature range when air temperature is selected as setting temperature.
CAUTION:
Only available when remote air temperature sensor is connected.
• Accessory PQRSTA0 should be installed.
• Also, Function Code 03 should be set properly.
• Function Code 14 : Setting Leaving Water Temperature in Heating Mode
Determine heating setting temperature range when leaving water temperature is selected as setting temperature.
• Function Code 15 : Setting Sanitary Tank Leaving Water Temperature
Determine heating setting temperature range of water tank leaving water.
NOTICE
Only available when sanitary water tank temperature sensor is installed.
• Sanitary water tank and sanitary water tank kit should be installed.
• DIP switch No. 2 and 3 should be set properly.
• Function Code 17 : Setting Operation mode lock.
Set the Operation mode lock when Multi V Indoor unit is used only cooling mode in summer and Hydro Kit is used
only heating in winter.
NOTICE
CH51 error occur when Combination Ratio exceed limitation without setting operation mode lock.
