Hi, the Hitachi Split remote control model RAR-52P2 runs normally and then out of the blue, one fine day stops displaying the temperature and the split does not cool. When fiddled with the temperature goes up to 3 C max (as shown on the remote display). It does not cool either. How do i get the remote back to normal where it lets me increase the temperature to 26 C and enables me to control the fan speed. I tried resetting it, but nothing happened. it has new batteries and all too

I found a manual for the Hitachi PC-P1HE which might be similar to your model. According to the manual, if the unit is turning on by itself, it could be due to a malfunctioning remote control or a timer setting. Here are some steps you can try to resolve the issue:

Check if the remote control is malfunctioning by removing its batteries and see if the unit still turns on by itself.
If the unit still turns on, check if there is a timer setting that is causing it to turn on automatically. You can refer to the manual for instructions on how to disable the timer setting.
If none of these steps work, it might be best to contact your service contractor of HITACHI for further assistance

Just take the battery out from its compartment. The remote control will reset itself. Insert the batter after some time.

Sounds like a faulty outdoor controller board. If you are in Australia, call Prime Electronics or Statewide Appliances for spares.

• To make a diagnosis
1. Timer LED start to blink and the unit automatically stops the operation.
2. Press the CHECK button on the remote controller continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display.
Note: Display only for "- -". (No transmitting signal, no
receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote controller. The code "H00" (no abnormality) will be displayed and signal will be transmitted to the main unit.
5. Every press of the button (up or down) will increase abnormality numbers and transmit abnormality code signal to the main unit.
6. When the latest abnormality code on the main unit and code transmitted from the remote controller are matched, power LED will light up for 30 seconds and a beep sound (continuously for 4 seconds) will be heard. If no codes are matched, power LED will light up for 0.5 seconds and no sound will be heard.
7. The breakdown diagnosis mode will be canceled by pressing the CHECK button continuously for 5 seconds or without any operation the remote control for 30 seconds.
8. The LED will be off if the unit is turned off or the RESET button on the main unit is pressed.

Or better yet, get a tech to check first.

abhay .hi their is a problem in my remote

I just bought a Sportline 241 last week. The instructions are as follows. Note that there are no instructions for setting the 12/24 hour time option. Mine is in 24 hour mode (which is what I wanted), but I do not recall if it arrived that way or if I stumbled onto this mode when setting the time/date or alarm functions.

I hope this helps.

Fujitsu, Mitsubishi, Sanyo mini-split indoor fan motors operate continuoulsy. The room-temperature sensor is inside the unit, so the fan motor needs to circulate air continuouly to sense room-air temperature. This is normal operation.
