System Set-Up
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 Domestic Hot Water tank Leaving Water Temperature
Determine heating setting temperature range of water tank leaving water.
NOTICE
Only available when Domestic Hot Water tank temperature sensor is installed.
• Domestic Hot Water tank and Domestic Hot Water tank kit should be installed.
• DIP switch No. 2 and 3 should be set properly.
