Basic Heating Operation
Notes:
(1) Condition for entering into Hot Dashed mode. When fan set to “Hi” or “Auto mode” and i) Indoor temperature is lower than 18
°
C, and ii) outdoor temperature is lower than 10
°
C,
and iii) Temperature difference between indoor temperature and set temperature has a corresponding compressor speed (calculated value in Table 3) larger than WMAX.
(2) Hot Dashed will release when i) Room temperature has achieved the set tempe SFTDSW. ii) Thermo off.
(3) During Hot Dashed operation, thermo off temperature is set temperature (with shift value) +3
°
C. After thermo off, operation continue in Fuzzy control mode.
(4) Compressor minimum “ON” time and “OFF” time is 3 minutes.
(5) During normal heating mode, compressor maximum speed WMAX will maintain for 120 minutes if indoor temperature is higher than 18
°
C. No time limit constrain if outdoor temperature
is lower than 4
°
C.
(6) During Hotkeep or Defrost mode, indoor operation lamp will blink at interval of 0.5 seconds “ON” and 0.5 second “OFF”.
(7) When heating mode starts, it will enter into Hotkeep mode if indoor heat exchanger temperature is lower than YNEOF + 0.33
°
C.
(8) When fan is set to
comprossor speed will be limited to WSZMAX.
“Lo”, compressor speed will be limited to WBEMAX. When fan is set to "Med", compressor speed will be limited to WJKMAXG. When fan is set to “Silent”,
(9) In “Ultra-Lo” fan mode, if indoor temperature is lower than 18
°
C, indoor fan will stop. If indoor temperature is higher than 18
°
C + 0.33
°
C, fan will continue in “Ultra-Lo” mode.
During Hotkeep or Defrost mode, fan will continue in “Ultra-Lo” mode.
(10) During Hot Dashed, when room temperature reaches set tempe SFTDSW compressor speed is actual speed x DWNRATEW.
