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 gener-
ation 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.
• Function Code 18 : Screed drying mode.
After installing water pipes for under floor heating, user can select screed drying mode for curing the cement.
