“Water tank” from “With” to “Without”, then “Hot water” mode will be automatically changed to “Heat”,
“Cool+hot water”/ “Heat+hot water” changed to “Cool”/ “Heat”.

13
(f) Temperature Setpoint
• The control is able to decide the temperature type and temperature range based on the current “Clock
Timer”, "Floor cong", “T-water Ctrl.”, and “Ctrl. state” settings. See the followings for more details.
• If the set mode is “Hot water”, the temperature set point shows nothing, indicating there is no need to
set “T-water out” and “T-room” but only “T- tank”. If the set mode “Cool” or “Heat”, then water tank
temperature box will show nothing, indicating there is no need to set “T-tank”.
