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.
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.
Water condensation on the floor
• While cooling operation, it is very important to keep leaving water temperature higher than 16°C.
Otherwise, dew condensation can be occurred on the floor.
• If floor is in humid environment, do not set leaving water temperature below 18 °C.
Water condensation on the radiator
• While cooling operation, cold water may not flow to the radiator. If cold water enters to the
radiator, dew generation on the surface of the radiator can be occurred.
• Function Code 13
: Setting Air Temperature in Heating Mode
Determine heating setting temperature range when air temperature is selected as setting
temperature.
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.
Only available when sanitary water tank feature is installed
• Sanitary water tank and sanitary water tank kit should be installed.
• DIP switch No. 2 and 3 should be set properly.
